Question 1

cyl eye test -2.5 means what?

Accepted Answer

Astigmatism: The 'cyl' column in your eye prescription refers to astigmatism.  You can think of astigmatism like warping on the surface of your eye -- like a football shape compared to a basketball shape.  You have 2.5 diopters of astigmatism.

Question 2

is 20/30 on a eye test passable?

Accepted Answer

Yes but . . .: 20/30 if best corrected vision, is one line less good than the standard 20/20.  It is still good vision; for instance in many states the minimum standard for an ordinary driver's license is 20/40 so someone with 20/30 would pass that test.

Question 3

where can i go for an eye test ?

Accepted Answer

Eye doctor: You can go to an ophthalmologist (eye doctor) for an eye test. If you want just a visual acuity test (meaning to check if you need glasses/contacts), you can go to an optometrist. I recommend googling local eye doctors in your area, or calling your PCP for a recommendation.

Question 4

how to pass the air puff eye test?

Accepted Answer

Glaucoma test: The "air puff" test is just a method to measure the pressure inside your eyeball.  High pressures may require additional work up.  Without medication or surgical intervention, you cannot lower you eye pressure to "pass" the test.

Question 5

how are eye vision test generally scored?

Accepted Answer

Compared to standard: The chart used to test the eye is calibrated for normal vision at 20 feet. The outcome achieved is compared to what a normal eye can see at 20 feet. So if you can only see at 20 feet what a normal eye sees at 40 feet, your vision is considered to be 20/40. This is measured with and without corrective lenses at distance and at near. The vision with correction is considered to show the true vision.

Question 6

what to do if i had my eye test the other day..?

Accepted Answer

Depends: Was this for glasses that you might need or for some condition?   You need to supply more information to allow a proper answer to this question.

Question 7

what to expect at my eye test appointment tomorrow?

Accepted Answer

Complete eye exam: In a complete eye exam, an assistant will typically obtain your history, along with whatever medications and allergies you have.  Then your visual acuities will be checked with a refraction to determine if you need glasses.  The doctor will examine all of the structures in the front and back of your eyes, along with checking your eye pressures.  Drops may be used to dilate your pupils temporarily.

Question 8

what kind of eye tests should children regularly get?

Accepted Answer

Depends on age: Infants and young children should have their red reflexes checked at routine well visits.  Older infants and very young children should be screened for strabismus.  Those who are developed enough to read an eye chart should be screened annually for visual acuity.

Question 9

what is the name of a machine that tests the pressure in the eyes?

Accepted Answer
