Have macular pucker in both eyes stage 2. Blurry driving and using computer but not reading a book, newspaper or watching tv. Why?
Depends on location: It depends on the location of the epiretinal membrane causing your macular pucker. Reading vision primarily depends on what is happening in your fovea. if the membrane is not affecting the fovea, you will read fine, but see blur elsewhere. Because most people describe macular pucker as distortion rather than blur, consider that the blur may also have other causes like cataract. ...Read more

I read article in the Daily Mail(Jan.2017)about digital devices and eye health.It left me wondering if watching tv's or computers damage retinas?
No damage: Studies have concluded that in order to cause any damage to the retina from light (phototoxicity) a bright light would have to be focused sharply on the retina for over 45 minutes. Most conscious patients could not tolerate this without blinking. Studies were done in primates (monkeys) and after 45 minutes of intense light a scar can be generated. Looking at a solar eclipse can cause damage too ...Read moreSee 1 more doctor answer
I was hit by a blunt object forcefully on the left eye , followed by bleeding from the lid & blur vision what precautions to take avoid driving ?
Yes: If you are constantly looking at a fixed near distance - like a computer your eye muscles may undergo spasm and you may develop induced nearsightedness. Thats why every 20 minutes of close work look at least 20 feet away for 20 seconds. My 20/20/20 rule. :-). ...Read moreSee 1 more doctor answer
Not really: Your eyes will hurt if there is potentially any problem. If you are feeling discomfort or outright pain doing any activity after dilation, listen to your body and temporarily stop that activity. If feels ok and no discomfort, it's fine. ...Read more

Tics? If all the : Studies were normal, remember that 11% of children with ASD have tics. The latest studies show that kids with adhd who develop tics on the stimulants methylphenidate (concerta) ; amphetamines usually have an underlying tic disorder, so the meds unmask tics rather than induce them. Compulsions? Maybe, but usually not myoclonic. Adding Intuniv for adhd may reduce them, if they are complex tics. ...Read more

No: There are no known "excercises" that have been shown in good medical studies to permanently improve your best corrected vision. The visual system is not the same as your muscular system so more repetition does not improve your vision. Looking at an eye chart every day will allow you to test your vision and alert you to any changes or weakening of your vision. ...Read moreSee 1 more doctor answer
What are the differences between an eye chart that starts with 20/200 and another that starts with 70ft-21?
Borderline to what?: Eye charts are printed in discrete steps and depending upon where your vision falls, you have reached one or another border. For instance 20/200 is a common border for legal blindness. 20/40 is a common border in most states for legal driving. 20/20 is the commonly defined average normal vision. It is the upper border of superior vision at 20/15 or better. ...Read more
If you can read an eye chart at 20ft as well as a person with normal vision at 30ft is vision 20/30?
Visual acuity: Now a person with "normal" eye sight should be able to read the row of letters of a certain size ( the 20/20 line) standing or seated 20 feet from the eye chart as any person with normal vision should be able to do. Yes, your vision would be 20/30 if you can only see the chart at 20'. But if you can also see it at 30', you would have 20/20 vision. ...Read more
No: It depends on the size of the print on "line 8" and the distance from the chart. It is common for people to read the 20/15 equivalent, and not unusual to read 20/12, but the limit is probably about 20/10. ...Read more
Read smallest line: The snellen chart is a graded series of letters or numbers smaller as you go down. The uncorrected vision is the smallest line easily read with each eye. Your ophthalmologist will present you with lenses to improve the level of the smallest line to hopefully get you to 20/20 - the standard of normal. It is a subjective test requiring your active input. ...Read more
Lengthens light path: Most offices do not have a 20 foot lane. But standards and available charts are made to reflect a 20 foot lane. The way to handle this is to use mirror (s) to reflect the image the proper distance to approximate a 20 foot lane. The letter images can also be enlarged or diminished as needed but this will change the standardization. A 20 foot light path is the standard. ...Read moreSee 1 more doctor answer
Yes: Your question specifically address visual acuity which is a measure of the acuteness of vision. If anyone has concerns about their acuity, please visit your optometrist or ophthalmologist. Acuity is best assessed one eye at a time. Roughly an eye should be able read newsprint (or smaller) at the normal reading distance. Now, it's easy to download apps for your phone to test acuity. ...Read moreSee 1 more doctor answer
Macular pucker, lost 1 line on eye chart in 1 year to 20/30. Is it likely next year I'll lose a line to 20/40 and continue at that rate of progression?
Hard to predict: Macular pucker is a variable condition and follows no rules. Yours may have maxed out or it might progress further. I am guessing you have a home testing card termed an Amsler grid to monitor any changes. If not, ask for one from your retinal specialist at the next appointment. ...Read more
Please tell me the connection between vision on an eye chart (say, 20/20 or 20/50) and eye prescription (-1 or -2.5)?
How do doctors know what prescription is needed for baby eyeglasses, if babies can't read an eye chart?
Refraction: Refraction is the measurement of how much the eye bends light. Refraction can be performed subjecively - the doctor shows the patient an image through progressively stronger lenses until the patient sees clearly - or objectively, by measuring how reflected light from the eye is bent and using lenses to "straighten" the bend without the patient giving his/her input. This method is used for children. ...Read more
Yes: Most of the slides used for projection of the snellen lietters for determination of acuity and refraction, have a section with pictures, numbers and an e chart. Ask your ophthalmologist if you need to use one of these. Most kids over 2-2 1/2 can be taught the e game. ...Read moreSee 1 more doctor answer
I recently took a tumble and hit my face on the ground. I have scrapes all around my eye and forehead. What would be best to put on cutsthis for best ?
Have had a stye for 3 months, greatly improved but still very noticeable, doesn't hurt but is very ugly, y can't I wear contacts? it doesn't hurt my eye when I eat contacts but I'm wondering if it makes my eye worse.
Chalazion: Your stye has probably transposed into a chalazion- a cystic nodule in the lid where the stye once was. This can be removed in an office procedure by your ophthalmologist. In the meantime, there is no reason why you cannot wear contact lenses as they will not aggravate or cause a stye ...Read more

3 yrs old has diarhea for 5 days. Whites of her eyes seems likely washed out. i.e really white. Why could it be?
Possible dehydration: When the body is deprived of fluids or has abnormal losses such as diarrhea, the blood vessels contract to preserve circulation to the vital organs such as brain, kidneys and heart. I strongly recommend giving oral rehydration solution and this can be Pedialyte, or made from ORS packets, or make your own from 6 teaspoons (30 ml) or sugar + 1/2 teaspon (2.5 ml) salt in 1 liter of H2O. See doctor ...Read more
What are narrow angles in my eyes? I am 63 and dr. Said i was born with this. Why was it never diagnosed before? I do not have pressure in my e
Glaucoma suspects: Narrow angle is an anatomical configuration formed by the insertion of the iris as one side and the curve or the inner cornea on the other. People who have small eyes (usu far sighted), of certain ethnicities such as chinese, vietamese, korean may HAV higher risk for sudden elevations of eye pressure resulting from this narrow angle which can lead to acute glaucoma attack and loss of vision. L. ...Read more
I have been seeing rainbow halos after i had put some chemicals in the eyes 8 yrs back, doct says nothing wrong. Gave me just tears e/d. Will it heal?
Rainbow haloes: Based on your history, the issue is not likely going to resolve. It may be related to corneal scarring and irregularity related to prior chemical exposure. I would continue the artificial tears and consider getting a rigid gas permeable contact lens fit to eliminate any possible corneal irregularity. See an eye doctor for this consideration. ...Read moreSee 1 more doctor answer
