Want to ask me the right cylinder axis 45 is the left one 0. But the same optics with the left axis is 180 hatched is it the same?
Hello, thank you for the question to HealthReplies.com
Axis on the cylinder of glasses is usually written between 1 to 180 degrees. The 0 and 180 degree axes are the same. Glasses also have an axis tolerance of up to 2 degrees, so that if you are given glasses for example with an axis of 1 degree will still be tolerable by your eyes and will not cause significant interference with your eyesight.
So much information from me, hopefully enough answer
