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 moreSee 1 more doctor answer
I took vision express online eye test and it said that my eyesight was 17% above average, what to do?
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
I've been having vision disturbances in my left eye for 3 years now. All test results are normal. What should I do?
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
Had a eye test and eyes seem fine but I keep seeing a black dot in my vision and even when I close my eyes. It stays on one position then goes?
Vitreous floater: It sounds like you have vitreous floaters, little grayish spots of differing shapes in the vitreous cavity of your eye. These increase with aging, myopia, lattice degeneration, and can arise from retinal tears, inflammation, trauma, surgery. The dilated eye examination is important to rule out serious causes that need treatment. As long as this has been done, just monitor for change. ...Read more
Wondering why eye vision went from -2.25 to -2.75 within less than a year. Seems a lot. Was stressed between that time. Recent opthalm. test: VGood.
Not significant: The final numbers for vision are based upon subjective information which includes how you felt on the day of the examination, how sharp was the eye doctor doing the measurements, lighting in the room, etc. There is some room for values to be up and down. Your number went up 0.50 which is not a great movement and may reflect these uncertainties. Nothing here to worry about. ...Read more
I went to get a regular vision test and was told my eye seemed swollen behind. I have to see a specialist and I am scared. What could this mean?
Many options: You are probably lucky that this was found. There are a number of reasons for swelling either in the back of the eye or behind the eye. I am guessing you are seeing an ophthalmologist who can sort this out for you. Eye treatment has advanced significantly in the last decade so I wouldn't worry at this point. Just be curious as to what it is. ...Read more
Glaucoma in 1 eye. damage to nerve. Dr. said is controlled & field hasn't changed but I have noticed vision change when driving. Why not show in test?
Generally not: Visual field tests are used to assess optic nerve function, most commonly in glaucoma. They can be used to identify possible strokes as well. The only weak muscle that could be identified would be the upper eyelid muscle in ptosis, as this would show obstruction of the superior visual field. ...Read moreSee 1 more doctor answer
How do I get rid of double vision? I have reading /comprehension problems. I am doing the #3-3 cups test, is it healthy with unfocused eyes?
Eyes test was perfect 20/20 vision. I see black spots flashes and Sparks of blue but my eye test was perfect nothing wrong. What could be the cause?
Possible migraine: If you are seeing these spots and sparks in a pattern and for some defined period of time (15-30 min) this could be due to migraine visual phenomena. If it is just a momentary thing then it probably relates to the vitreous gel in one or both eyes getting a bit more liquified. ...Read more
