My son is 4 yrs old and we took him to eye test since he didnot read some letters in the well visit. We think he might be playing. We took him to opthamologist, where he was given prescription to wear eye glasses. His powers are
OD -2.50 +2.00 *080
OS -2.50 +2.50 *100
Is this power too high, does it mean he has both sperical and cylindrical power. Does it mean he has very blurry vision, which we could not say from the way he sees things. We never thought he needed glasses. Is it very essential to wear glasses at this age, since we are not sure how sure he has problems.
