Can a pinhole test determine if you have lazy eye or not?

Can a pinhole test determine if you have lazy eye or not?

Not definitively: Pinhole helps to test for any refractive error, and can help predict best potential acuity (pap). Lazy eye amblyopia is defined: DX of exclusion, once the visual pathway is determined to be ok but the vision is still limited due to developmental changes in the brain visual cortex. ...Read more

I have seen a lot of mixed opinions on if pinhole glasses will help one's eyes, but will wearing them do any harm?

I have seen a lot of mixed opinions on if pinhole glasses will help one's eyes, but will wearing them do any harm?

No harm: Pinhole glasses only allow the image to be projected through the center of your cornea and lens where no refractive error will blur the image. This does no harm, but also won't help your underlying refractive error. ...Read more

Thoughts? Could pinhole glasses hurt/damage one's eyes?

Thoughts? Could pinhole glasses hurt/damage one's eyes?

No: Wearing or not wearing glasses, including pinhole glasses, will not damage eyes. Pinhole glasses provide better visual acuity at the cost of poor or non-existent side vision and need for lots of light to see. ...Read more

Can pinhole glasses help improve eyesight or reduce eye strain?

Can pinhole glasses help improve eyesight or reduce eye strain?

Yes: Pinhole can help sharpen vision, but at the expense of decreasing your field of vision (see straight ahead only with no peripheral). Eye strain can be reduced by having the proper refractive correction. ...Read more

Cyl eye test -2.5 means what?

Cyl eye test -2.5 means what?

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. ...Read more

How are eye vision test generally scored?

How are eye vision test generally scored?

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. ...Read more

Does cornea eye thickness test hurt?

No pain: There is a slight stinging from the numbing drop applied before the test. The test touches the center of the cornea with an ultrasonic, tiny probe which you will not feel. One touch is all and the data is recorded. Not a test to be worried about in the least. ...Read more

What do sph, cyl and axis mean on an eye test?

What do sph, cyl and axis mean on an eye test?

Specific parts of Rx: To expand on dr. Proffitt's answer, sph = sphere; if this is a negative number, the prescription is a myopic or nearsighted prescription and a positive number dictates a farsighted or hyperopic prescription. Cyl = cylinder or the amount or power of the astigmatism correction. Axis is the direction in which the astigmatism correction is placed in the glasses. ...Read more

What do sph, cyl and axis mean on your eye test?

What do sph, cyl and axis mean on your eye test?

Glasses Rx: Sph is sphere power or the focusing power of the lens. A negative number means you are near sighted and positive is far sightedness. Cyl is cylinder power or the astigmatism correction in the glasses. It is aligned on an axis, the last number. ...Read more

Can you tell me what an amsler grid is for on any eye test?

Amsler Grid: Is 1/4 inch graph paper with a dot on it. With each eye, you stare at the dot and pay attention to the lines. If the lines are missing or not straight, mark the area and call you ophthalmologist. This was described by french ophthalmologist marc amsler. ...Read more

Can normal eye tests show up if someone suffers from glaucoma?

Can normal eye tests show up if someone suffers from glaucoma?

Complicated: No single test is 100 percent for diagnosing glaucoma. As such, some tests may be normal (ie normal field of vision) while other tests (such as tests of eye structure) can show damage. Glaucoma involves damage to the eye - so if all the tests are normal and the optic nerve looks healthy then by definition that person doesn't have glaucoma (though they may be at high risk for getting it later on). ...Read more

Can normal eye tests show up if someone suffers from glaucoma?

Can normal eye tests show up if someone suffers from glaucoma?

Routine screening...: For glaucoma should be performed with any type of Eye exam. Typically this will include a vision and an eye pressure. However it is all known that one must look directly at the optic nerve to best assess whether not glaucoma is present. This is not always performed at every eye exam. If there is concern or an increased risk for glaucoma, that should be communicated well at time of visit. ...Read more

Can I use sph, cyl and axis of my eye test to rate my vision strength?

No: These numbers do not translate directly into a snellen acuity number (like 20/20). The degree of visual clarity is different than the eyeglass strength to achieve that clarity. ...Read more

What do you suggest if I could use sph, cyl and axis on my eye test to rate my vision strength and if yes how to rate my vision strength?

Yes: The best number to use is sphere (sph). If you are nearsighted or myopic the number has a minus sign in front of it. The higher the number, the worse your uncorrected vision is.
If you are farsighted, the number is a plus sign and the same applies. The cyl stands for cylinder and is a measure of astigmatism. The higher the number, the worse the astigmatism ...Read more

I have a visterious seperation in my right eye. I also have had to catracs repaired. Is seeing my optomitist enough for the drop tests.

Eye issues: Posterior vitreous detachment and catarct surgery are both factors that can increase your risk for retinal tears or detachement. You should see an eye care provider who will not only dilate your eyes, but do a peripheral exam of the retina with a contact lens to macke sure no holes, tears or other pathology is there. ...Read more
