Do you get your eyes checked annually? Once every two years, maybe? No, not even then? Do you remember the last time you even went in for an eye exam?!
The answer to the last question for the most of us is unfortunately no. A common misconception about eye health is that if there isn’t anything obviously wrong, we don’t need to go to the eye doctor.
However, just because your eyes are seemingly healthy that doesn’t mean that they are. In fact, a lot of common eye conditions can have no symptoms or signs until it is too late to do anything about it. A lot of common eye conditions are preventable if caught early.
Unfortunately, when we don’t go for an annual eye exam because we think our eyes are healthy, we’re then surprised by severe eye conditions and sometimes diseases that develop.
Glaucoma is an example of a no symptom eye disease. Most patients only exhibit symptoms and signs of the disease when it has already progressed past the point of curing.
Honestly, you wouldn’t avoid visiting your physician just because you didn’t notice anything wrong with your body this year. We have no way of telling what’s truly brewing beneath the surface unless we seek professional help and advice. The same goes for eye care. Just because your eyes seem healthy, doesn’t always mean they are.
These nasty surprises can be easily avoided. All you need to do is, you guessed it, go see your eye doctor.
When to Get Your Eyes Tested
Knowing when and how often to get your eyes tested is sometimes not an easy thing to know. Do you have to go every year or every two years? Well, the answer isn’t quite as clear cut as that.
All eyes are different and unique. Eyes are so unique, that your own two eyes aren’t even the same. That’s why figuring out when to check your eyes really depends on your overall health, your eyes’ health and your overall needs.
Before we get into specifics, let’s talk about your “healthy” eyes. So you think your eyes are healthy. No blurred vision, eye strain, night blindness, etc. Good for you! That probably means you’re doing a great job taking care of your eyes.
You’re probably an avid reader of our blog too, right? Wink, wink.
All right, so healthy eyes all around are great. Maybe your eyes are actually as healthy as you think they are. But even so, eye doctors often recommend having a comprehensive eye exam every two years for adults.
Children and seniors over the age of 60 should get an annual eye exam. This is especially important for children, whose developing eyes are constantly changing, and seniors who are at risk of developing age related eye diseases.
Let’s say you have an existing eye condition or are “at risk.” How often should you see your doctor? The general recommendation is annually or biannually, depending on what condition you have. If you have an existing condition, ask your eye doctor how often you should pay them a visit. They’ll be able to give you a better idea.
You don’t need to have an existing eye condition to be “at risk.” The following factors can make you at risk of developing certain eye conditions and diseases:
- Family history of eye diseases
- Previous eye injury
- High blood pressure
- Prescription medication with vision altering side effects
A lot of external factors can affect your vision. To be safe, have a dialogue with your eye doctor about how often you should be getting your eyes checked.
Eye Exams: What to Expect
We use the very general terms of getting your eyes “tested” or “checked,” but what does that really entail? Reciting letters off a Snellen chart? Distinguishing different shades of various colors?
See, because the eyes are so complex, there are a number of tests that exist to test every part of the eye. When you go for your comprehensive eye exam, you can expect to be tested with the seven main tests.

The Seven Main Tests
1. Visual Acuity Test: This is the most common test and the test that is most often featured in film and television. This is the test that uses the aforementioned Snellen test. This will test the sharpness of your vision.
2. Color Blindness Test: This is test is often done at an early age. The most common test is the Ishihara Plates In this test, the patient is asked to identify the number or shape within the circle.
This tests for red/green color blindness. If colorblindness is detected, a more comprehensive eye screening may be needed to truly know how colorblind the patient is.
3. Ocular Motility Test: An ocular motility test is a fancy way of saying your doctor will be testing your eye movements. This test is simply done by holding your head still (sometimes your doctor may hold your head still for you) and then you’ll be asked to follow a light or an object using your eyes only.
This test, though simple is very important as slow or “jumpy” eye movements can cause eye strain, which can lead to a number of other complications.
4. Cover Test: This is another common test in children, but is also performed on adults on occasion. In this test, your doctor will have you focus on something across the room and then cover one eye. This is used to test to see how your eyes work independently of each other.
Often this test will detect amblyopia, otherwise known as lazy eye. Lazy eye is a very common, but easily treatable condition in children. Adult amblyopia is not as common and not as easily treatable, but doctors are constantly striving to find a cure for adult lazy eye.
5. Stereopsis Test: A stereopsis test will test your depth perception. The most common of these tests will require you to don some cool 3D glasses. Looking through the glasses, you’ll be asked to look at a pattern of four circles. Then you’ll have to point out which circle looks to be the closest to you.
6. Slit Lamp Exam: This exam is easy, because all you need to do is sit in front of a slit lamp and flash those beautiful eyes of yours. Through the slit lamp, your doctor will study the structure of your eye. The structure of your eye can be quite telling. This test will reveal the presence of cataracts, ulcers, macular degeneration and diabetic retinopathy.
7. Puff-of-air Test: This last test on our list is a test that will measure the intraocular pressure of the eye to test for glaucoma. The technical term for this test is non-contact tonometry, but puff-of-air sounds less scary.
For this test, a puff of air will be blown into your open eye. Based on your eye’s resistance to the air, your doctor will be able to determine if you are at risk or have begun to develop glaucoma.
As we mentioned before, there are no warning signs for glaucoma, so you’re better off testing it just to be sure. Trust us, the puff-of-air test is painless but glaucoma is not.
Bonus test! Pupil Dilation: This test isn’t always performed during a comprehensive eye exam but it’s still an important one. Using eye drops, your doctor will dilate your pupils to better study the inner structure of the eye. This test is normally done only if it needs to be.
