What is a "click" with regards to vision?!
Question: What is a "click" with regards to vision?
So, what's a 'click'? I have trouble seeing distance and I have an astigmatism in each eye. I don't know my specific prescription, except that my old contacts were in the -3 range, I believe. What is a 'click' relative to that number (like, is it -.5 or something?)?
A click is a 0.25....2 clicks is 0.50
By a click , he just means the next step up on the phoropter which makes a little " click " when the lens is turned to the next strength.
