A member asked:
Can you guys tell me how big a deal is -0.5 diopters to mis-measure?
A doctor has provided 1 answer
Minor: This is easily within the range that your eye can adjust to it and measurement of optical strength can include at + or - factor of 0.5 easily since the measurement is subjective. So it is not a big deal.
