This is an image captured while waiting the eye doctor for my annual eye exam. A phoropter is an instrument commonly used by eye care professionals during an eye exam. A phoropter contains many different lenses used for refraction of the eye during sight testing, to measure an individual's error of refraction and to determine an individual's eyeglass prescription. Thanks for visiting and please come back often!
