We often get questions about what an eye exam is like, so we’ve created an overview of a typical eye exam in our office.

Regular comprehensive eye exams are key to early detection of eye-related diseases to keep you seeing your best every day. Adults should have a comprehensive eye exam every 1-2 years. Children should have an eye exam as early as 6 months, before they start school, and then every 1-2 years. If you or your family need a comprehensive eye exam, contact our office to schedule an appointment.

Eye Exam Basics

What does an eye exam test for? Eye exams test your visual acuity and the overall health of your eye.

Why is an eye exam important? Eye exams check for early signs of serious eye and health problems; some of which may not present with any symptoms.

Who gives an eye exam? Your eye exam is performed by a licensed eye doctor.

Terms to know:

• Ophthalmologist: An ophthalmologist is a medical doctor (MD) who specializes in eye care. Ophthalmologists can prescribe eyeglasses and contacts but commonly specialize in treating medical conditions of the eye and performing eye surgery
• Optometrist: Optometrists are eye doctors who prescribe glasses, contacts, vision therapy, and medication to treat eye diseases. Optometrists are not trained or licensed to perform eye related surgery.
• Optician: An optician is not an eye doctor, but is an eye care professional who fits, adjusts, and repairs your eyeglasses. They can also help patients learn to apply, remove, and care for contact lenses.

What to prepare for your appointment?

Before your comprehensive eye exam, there are several materials you can prepare. First, create a list of all your prescription and non-prescription medications you take along with the dosage. This will help your eye doctor determine any vision risks you may have. Bring your most recent pair of eyeglasses or contact lenses, if you have them. Don’t forget to have a copy of your vision insurance card and other medical insurance cards with you. To learn more about the insurance providers our office accepts and other payment options, please call our office directly. Finally, bring a list of questions or concerns you may have about your eyesight to discuss with your eye doctor.

What to expect during your appointment?

Prepare for your eye exam to take an hour or more depending on the number of tests your eye doctor needs to evaluate your vision and eye health. A typical comprehensive exam is a series of visual tests to inform your eye doctor about your vision.

These tests help determine:

• Sharpness of near and distance vision
• Color blindness
• Lazy eye
• Ability to follow moving object and/or move between two separate fixed objects
• Depth perception
• Determine your eyeglass prescription
• Structures of the eye
• Glaucoma test
• Eye drop test to look inside your eyes
• Blind spots

What to do after the exam?

Following your exam, you will have the opportunity to explore the various frames and lenses found in our optical space. An optician will be available to assist you in selecting a pair of eyewear that best fits your lifestyle needs. If you choose to wear contact lenses, you will need to schedule a contact lens fitting appointment.

Once your new eyewear is ready to be picked-up, an optician will adjust your frame to fit you best and make it comfortable for everyday wear.

Finally, schedule your follow-up appointment for the next year. Regular comprehensive eye exams are essential in maintaining healthy vision. If you ever experience any sudden vision changes or eye injuries be sure to contact our office.

Vision therapy is not one singular thing. This type of treatment is a customized program created by an eye doctor and performed under his or her supervision. Vision therapy encompasses exercises and activities that are non-surgical and they aim to correct certain vision problems or vision-related skills.

The confusion over vision therapy tends to come from many sources on the internet that claim to help people get rid of their refractive errors. It is not uncommon to see posts and articles about how someone used “eye exercises” for some seemingly short period of time and then magically they don’t need glasses any more. They have 20/20 vision now, right? If only that were true!

Can you train yourself to see better?
It is not possible to do simple exercises from the internet to “train” your eyes to no longer have a refractive error. Refractive errors stem from irregular shapes of the eyeball, shape of the cornea, or elasticity of the eye lens. Moreover, this is not vision therapy. Vision therapy is done with a trained eye doctor and does not claim to change the lens of the eye.

Instead, vision therapy is usually coordinated by an experienced eye doctor for someone with an eye disorder relating to eye muscles, and other structures that have to do with focusing, eye alignment, and how your eyes work with other parts of your anatomy to complete complex tasks and develop certain skills.

Because of the confusion with internet and mail-based “treatments” that have seen a rise in the last several years, we feel it is especially important to make sure patients understand vision therapy. If you have any questions about this or have concerns about your eyes or the eyes and visual development of your children, contact us to schedule an appointment. We will be happy to help!

Most of us remember being told not to sit too close to the TV because it would ruin our vision. Well, that may have been an exaggeration of the actual dangers of sitting too near a tube television, but new risks are at play when it comes to electronic screens and the eyes of our children.

Old tube televisions and things like handheld games relied on much different electronics and lights to power their screens in the early years. It wasn’t until much more recently that we have moved to bright, LED and plasma screens that use a lot of blue light to show unimaginably crisp images. Whereas sitting pretty close to one of those screens twenty years ago probably wasn’t a good idea, it’s likely that prolonged and extreme use of screens nowadays is more problematic.

We know that using a computer can improve school readiness and academic achievement. Children learn digital tools quickly, and have relatively little trouble using them for educational games, math, reading, and more. These things aid cognitive development when used appropriately, and will not harm your child’s vision.

The risks associated with using a digital screen come from prolonged use, improper ergonomics, and developmental problems caused by getting too much screen time instead of getting social interaction and physical activity.

Children’s eyes are more sensitive to bright light because they lack certain tints that we develop as we get older. As we age, our eyes take on a slightly yellowish tint that helps filter bright blue light. The sun is the largest source of bright blue light, but digital devices also rely on this kind of light to produce clear videos and graphics. This means that children who use a bright screen up close are naturally less protected than older people, and their eyes are more susceptible to damage. Over time, our risk for macular degeneration increases along with years of exposure to “high-energy visible light.”

When children use a digital device for long periods of time, they do not “flex” their eyes by focusing on distant objects, as well as looking in the near and intermediate fields. This causes eyestrain. Additionally, sitting for too long and making repetitive movements with hands (like clicking a mouse or controller) or sitting in a position with bad posture or an unsupported upper body can lead to problems like carpal tunnel, muscle soreness, and poor physical development. Everyone knows that kids need time to burn off energy, build gross motor skills, and strengthen their muscles and bones through exercise and play. When they get too much time sitting down while indoors, other important activities like outdoor play, conversation, spacial reasoning, and other skills suffer.

To reduce your child’s risk of computer vision syndrome:

• Limit their time on computers and devices
• Prompt them to take breaks regularly (this is a good habit for many activities)
• Make sure they are sitting in a comfortable, supported position
• Opt for anti-glare protection on their eyewear to reduce eyestrain
• Teach them to view digital screens at arm’s length and not too close

Many medical professionals are aware of the benefits of adding healthy oils to our diets. Most of the fats that are essential for a healthy heart, skin, brain, and other systems come from things like fish, nuts, seeds, and vegetables. Doctors will sometimes prescribe fish oil or flaxseed oil to help improve someone’s health, but we are learning more and more about how these beneficial oils can help more than previously thought. In the case of your eyes, certain oils may aid in treatment of dry eyes.

Vision Benefits of Flaxseed and Fish Oil
Fish oil and flaxseed oil are beneficial because of the omega-3 fatty acids they include. These materials are needed to support optimal health. Flaxseed oil contains high levels of alpha-linolenic acid (ALA), an omega-3 fatty acid. ALA is converted into two different omega-3 fatty acids during digestion. These acids are called EPA and DHA and they protect cell membranes all over the body.

By adding flaxseed oil or fish oil to your diet, you may be protecting against dry eyes. These items appear to reduce dry eye symptoms, and can be used with or without eye drops to alleviate some aspects of dry eyes. Many eye doctors are recommending fish oil or flaxseed oil as part of an overall plan to treat dry eyes, or to prevent the onset or progression of symptoms.

Symptoms of dry eyes include:

• Chronic dryness
• Burning
• Stinging
• Redness
• Eye fatigue
• Sore eyes
• Light sensitivity
• Blurred vision

How to Start Taking Flaxseed and Fish Oil
If you’re looking for how to get these substances into your diet, keep in mind that many kinds of fish are high in these oils. Look for things like salmon, sardines, tilapia, and shrimp. For people who don’t like fish, or want other options, fish oil supplements are usually pretty inexpensive and easy to come by. You may ask a pharmacist for suggestions on which over the counter versions are best.

The downside of fish oil is that sometimes people will get a fishy aftertaste from the supplements. A great alternative is flaxseed oil. These supplements are readily available as well, and will provide similar benefits. Just be sure to find a brand that is cold pressed and remember to keep it refrigerated for freshness and optimal nutrient content (benefits of flaxseed oil are reduced by exposure to oxygen, light, and higher temperatures).

Flaxseed oil can get a little pricy, but you can buy flaxseeds and grind them in a coffee grinder before adding them to your diet. Use them immediately to get the full benefits!

Other Benefits
These fatty acids may help reduce your risk for several other health problems. The benefits include:
• Reduced risk of macular degeneration
• Reduced risk of cataracts
• Increased cardiovascular function
• Lower risk of heart disease
• Help maintain healthy weight

As is true with any health care, it’s important to find a doctor who is qualified to treat you. With eye care, you may be able to get an eye exam from a large number of practitioners. If you need to confirm a diagnosis, treat an eye disease, or have other unique needs like a pediatric or geriatric specialty, you will have to spend more time choosing the right eye doctor. No matter what your current vision situation is, it’s crucial to choose the right eye doctor for you and your family.

What is an Optometrist, Ophthalmologist, or Optician?
Many people use the term “eye doctor” to refer to the qualified individual who administers your eye exam and writes you a prescription for lenses to correct your refractive error. We know just how many distinctions there are between eye care professionals, however!

Most people who want to see an eye doctor will seek an optometrist. An optometrist holds a Doctor of Optometry (OD) degree and can examine eyes for vision or health ailments, visual acuity or refractive errors, and can prescribe eyeglasses or contact lenses. Some optometrists also provide additional services, like vision therapy and care plans for people with low vision.

An ophthalmologist is a medical doctor or osteopathic doctor who specializes in the eye. They can also perform eye exams, but they are more often used to diagnose and treat eye diseases, prescribe medications, and perform eye surgery. They are able to write prescriptions for eyeglasses and contacts, too.

Another term that people sometimes hear and may not know what the occupation entails is “optician.” An optician is not a doctor. These professionals are qualified to use prescriptions written by an eye doctor to help fit you for eyewear and explain use, care, and features of your glasses or contacts.

What kind of doctor should I see?
This depends on your vision and eye health. If you have not had problems with your eyes beyond typical blurriness at certain distances, and if you’re not concerned about risks of eye disease or more serious symptoms, generally you are fine to see an optometrist. If you aren’t sure and you see an optometrist, he or she will let you know if you need to seek treatment from an ophthalmologist.

How do I pick a good eye doctor?
This is up to you! Some people like to look at social media pages to see what is the personality of the practice. You may seek reviews from others online, or ask friends for suggestions. Others go based on convenience factors like when the office is open, how easily you can schedule an appointment, and proximity to your home or office. Some factors may require a visit. If you’re planning on getting new eyeglasses, most offices allow you to walk in any time that they are open to browse their selection of frames, and even to speak with an optician about specialty products and upgrades. This also gives you an idea of their customer service, friendliness, and general feel of the office.

Once you decide, you’re ready to make an appointment and get busy seeing your best!

Risks of blue light exposure have become a topic of discussion in recent years. More eyecare professionals and scientists are studying the effects of blue light to assess the effects of relying on blue light for so much of our lighting.

It’s hard to say for sure how much added blue light exposure may lead to additional cases of degenerative eye health problems like macular degeneration. Plus, there is some evidence that overexposure to high-energy blue light can cause side effects such as sleep disturbances, eye strain, and headaches. With this in mind, how can you reduce your exposure, inside and out?

Inside
• Lower the brightness of your electronic screens, especially at night, but make sure you are not straining to see the words if you’re reading.
• Take frequent breaks while working at a computer. Regardless of blue light exposure, Computer Vision Syndrome is another problem you may face, and taking breaks to relax your eyes will help.
• Stop using your devices at least a couple hours before bed. Unplug and read a book instead, which will give your eyes something easy to focus on and help you wind down for good sleep.
• Adjust your distance. Viewing a bright screen up close is fatiguing. Make sure to set your computer monitor and television at a comfortable distance, and don’t hold handheld devices too close to your eyes. You can adjust text size if reading a device at arm’s length is difficult.
• Opt for non-glare lenses. Non-glare or anti-reflective treatments on your lenses will help reduce bright lights affecting your eyes.

Outside
• Wear sunglasses. Sunglasses that are an appropriate darkness and block 99-100% of UVA-UVB rays are the best protection for your eyes.
• Consider polarized lenses, too. Polarization cuts harsh glares that bounce off of water and other surfaces.
• Don’t forget a hat! In especially bright outdoor settings a hat will help block bright light from above, even if your eyes are protected from the front.

Ask us about what blue light-blocking options are available for your eyewear. We can help with your everyday lenses, reading glasses, and especially with sunglasses!

It seems like contact lenses and glasses would use the same prescription. After all, the idea is that your eyes don’t see quite right, so you use a lens to change the view, and then you see clearly, right? Well, the two prescriptions are quite different. Few patients check the numbers or notice any change during the exam process, but the prescriptions are not the same because of where the lens sits in relation to your eye.

The lens of your glasses rests about twelve millimeters from your eye. Contact lenses, on the other hand, are placed directly on the surface of your eye. Why would this make your prescription different? Well, think about holding a magnifying glass out in your hand. When you hold it far away and look through, the view you see is much different than if you try to hold the magnifying lens up close to your eye. The same principle is in play when you consider glasses in contrast to contact lenses.

If you’re still imagining the magnifying glass held out in your hand, think about how grass would look if you’re sitting on the ground and have the magnifying glass down near the grass. You’d be able to see the blades clearly, right? If you held the magnifying glass up close to your eye, the refraction would be so strong that you wouldn’t be able to see anything other than a blur. The power of the glass would need to be reduced for you to see clearly. This is the reason why your contact lens prescription is weaker than your glasses, but you get the same crisp, clear vision with each. Neat, right?

Not all contact lens prescription powers are drastically less than the glasses prescription for the same person, but usually the power used for contact lenses is reduced. In addition to the powers being different, your eye care professional will need some additional measurements to fit you for contact lenses because there are specifications needed to fit contact lenses appropriately that aren’t needed for glasses.

Some things that need to be measured to receive an accurate contact lens prescription are the size of the cornea, the curve and overall size of the lens, and the suggested brand of lenses that will work best for you. Eye care professionals usually have an idea of which contact lenses work best with different eye conditions, so they will suggest a particular toric lens for your astigmatism, or a type of disposal lens based on your needs, for example.

Some aspects of the lens prescriptions are included for both kinds of eyewear. The lens power is included in both prescriptions. Lens power is the measurement used to correct your “refractive error,” or the nearsightedness, farsightedness, or astigmatism that you have. It wouldn’t be identical because of the magnifying glass analogy, but it is included in both prescriptions. They’re also laid out per eye—right vs. left—because very few people have the same prescription in both eyes, so they are measured individually regardless of what type of eyewear you’re getting. More technical aspects of your prescription (the power and axis determined to correct astigmatism, for instance) may also be included in both the contact lens and glasses versions of your prescription.

Hopefully that makes the difference between your contact lens and glasses prescriptions clearer. Talk to your eye care professional if you have any questions about your prescription or are curious about getting contact lenses or glasses.

Just as sports officials are becoming more concerned with overall physical safety for athletes, more people are wearing specialized eyewear to protect their eyes and give them protection and sharp vision while performing their sport. Specialty eyewear options are available and tailored to just about every sport. All you have to do is know your sporting needs and talk to an eye care professional to discuss your options. It’s nice to know what to expect and what you can get other than just wearing contact lenses.

Here are some of the most common options and things to consider for glasses, goggles, or other specialty eyewear with unique capabilities to increase your sporting performance.

Darkened/tinted or photochromic lenses. Is your sport outdoors? Protection from bright sunlight and UV rays is crucial! Watersports and winter sports involve glares coming up from the snow or water. The bright light is damaging to your eyes and very uncomfortable if you’re not protected. Certain color tints can also help make sports glasses more functional. Golf glasses, for example, often use a copper or amber color that improves the contrast of grass and sky so you can read the course better. Make sure that you invest in glasses that will fit your outdoor setting.

Fitting with other gear. Eyewear for activities like motorsports, cycling, or football will need to fit with headgear. Be sure to test your eyewear with your uniform or additional gear, and talk to your eye care professional about the other items you’ll be wearing along with your eyewear.

Durability. In sports like racquetball, or really any sport with objects that are swung or flung around, you face the risk of getting hit and injuring your eyes if they’re not protected. This also means that your glasses or goggles are likely to take a beating while protecting your eyes. Scratch-resistance and high-impact polycarbonate materials are often used in sports eyewear to be sure that they will have a long life and will be able to shield your eyes from harm.

Considerations for contact lenses. Those who wear contact lenses and will be doing their sport in the elements can benefit greatly from glasses that wrap around the face. Protection from wind and debris will ensure that no irritants enter the eye and affect your contact lenses.

Protection from other substances. Watersports may come to mind when you think of goggles that protect your eyes from liquid, but there are other sports like paintball that could greatly damage the eyes if not protected. Specialty masks with breathable vents that allow air in will be sure to keep paint out. Goggles for watersports have similar features to keep water out of your eyes so you can see clearly under the water or above.

Polarized lenses. Probably the most important aspect of eyewear for fishing is polarization. Polarized lenses make it possible to see under the surface of the water because the lenses are specially made to cut down refracted light. Once the sunlight bouncing off the water is minimized, it’s far easier to see into the water and read important fishing features like vegetation, depth, underwater landscape, and even fish! Other water and winter sports can benefit from polarization as well to prevent the eyes from glaring sunlight.

Make sure that you’re prepared for your sport with protective gear and the right eyewear to keep your eyes on the prize. See an eye care professional to give your eyes a sporting chance!
