How To Measure Radius Of Curvature Of Lens

We are also given the radius of curvature of the mirror so that its focal length is latexffracR2250text cmlatex positive since the mirror is concave or converging. However this will depend on the curvature of the back surface of the contact lens and the amount of spherical correction for myopia or hyperopia.


Measurement Of Radius Of Curvature Directly In The Interferometer Confocal Position

If a GP lens is selected with a base curve radius thats one-half diopter flatter less curved than the cornea a contact lens power of -275D would be predicted.

How to measure radius of curvature of lens. Assuming the mirror is small compared with its radius of curvature we can use the thin lens equations to solve this problem. For example in the left eye.
