A member asked:

I'm a 16 female. while my eye test , i could not a see a single letter of the snellen chart not even the biggest letter( without steroidal drops as i unfortunately couldn't get my complete prescription check) . what could be my prescription/power ?

A doctor has provided 1 answer

The Snellen chart gives a specific description of vision power if read from a set distance. 20/200 is the power of the largest letter at 20 feet. You did not cite the conditions of your view of this chart, which matters. Any distortion of your cornea by current "dry eye" edema or inflammation invalidates the test for acuity determination.
