Abstract :
Lens is the most general element in optic systems. In branch of ophthalmology and optic engineering measurement the power of lens is very significant. There are different methods and instruments to measure the power of lens, such as using standard lens box, using spherometer and using manual and automatic lensometer. The automatic lensometer is a way to avoid from human error. In this article we have designed an automatic lensometer based on image processing techniques.
