Eye tests? do they test every bit of the human eye?

Question

im 21 and im haveing my eyes tested soon, but do the tests know if theres even something a little bit wrong with the eyes, like for instance do they test every single muscle and glands?

Answer 1

Don't worry testing part doesn't hurt.  Its when they do surgery.

Answer 2

They can't test every little bit without surgery. What the doctor will really do is the following:

1 - Test your ability to focus at different distances, both close-up and far away.

2 - Using a variety of lenses that can quickly be changed out, the doctor will determine how the lenses affect your ability to focus based on feedback that you will be able to easily provide.

3 - Using another set of lenses, he/she will cause you to have double vision, and then the doctor will have you track each "object" you can see.

4 - The doctor move an object or his/her finger across your visual field to see that you can track it with your eyes.

5 - The doctor will bring a microscope up to your open eye to examine it.



They may test you for glaucoma, either by subjecting your eyes to a sudden puff of air, or by using a chemical that will force your eyes to dilate and examining them. If it's the latter way, I recommend that you have somebody help you get home, as the forced dilation will make the world seem unbearably bright until the effects wear off (I learned this one the hard way).

In the end, the doctor gleans a lot about your ability to see, and why you may or may not have difficulties. If there is a problem that the optometrist can't diagnose with the tools available, he/she may need to refer you to a specialist. However, my first optometrist was able to diagnose a problem in my eye muscles without needing a referral, simply based on how I could and could not focus at different distances.

Answer 3

I don't know.  There are different tests.  I don't think any one test would cover them all/.  If you're having a certain problem, just tell them and they'll perform specific tests, but I wouldn't worry about not having tested for everything.

Answer 4

No. That would be a VERY long exam. They generally just check your vision field to see if you have any blind spots (which would indicate deterioration of vision) and your vision strength (to see if you need glasses or contacts).

You can ask your optometrist (or opthamologist, if that's who you're seeing) to do a more comprehensive exam, and you probably should since I'm assuming you haven't been for an eye check-up in a long time.

*IMPORTANT-- You need to get an eye check-up EVERY YEAR, and babies should go for their first exam before they reach six months of age (at the very latest) to check for early-developing problems that could have very serious consequences if left undiscovered and untreated.

Answer 5

They test the eyes for everything. They give a very close visual examination of the health of the eyes and then the multitude of tests will ensure that should there be a problem, they can find the exact lense to correct the problem.

The eyes deteriorate with time, and I only started to need glasses at about 23. Now my eyes are pretty bad.

I am considering surgery in a few years to correct it permenantly.

Answer 6

Yes they do. I went for my eye-test, I was`nt having any problem, but the optition found I had developed glaucoma, and advised an eye consulant, I am having treatment now, so through finding the problem early ,little damage has been done.
