While practicing last Monday, i asked a resident to prescribe reading glasses for a 50 year female, who never wore glasses before.
Her autoref readings were +3.0/-1.5 x90
1- He prescribed +5.0/-1.5 x 90 OU with acuity 6/6, this is VERY wrong (it seems he did not read my posts ), like learning by repetition so let’s repeat.
Do NOT prescribe cylinders for the first time above 40.
In view of this we re-calculate the refraction as +2.0.
Based on the power of accommodation at 50, distance correction is +1.0.
NEVER increase reading glasses by more than 1.0 at a time.
The final reading prescription for this lady is +2.0 OU which can be bought ready made at the pharmacy.
It would be a shame for our practice that a patient finds that ready-made eye-glasses she bought from a cheap stand is more comfortable than our prescribed ones.
Please know how to prescribe GOOD glasses or surrender the job to optometrists.
