How do optometrists determine what strength prescription a toddler needs with such limited communication skills?
In: 7
When I was really young I remember they used to have a machine and you looked into it and everything was blurry and then all of a sudden a desert scene with a road and a cactus would come into focus and then go blurry again. This would spit out your approximate prescription. You would then go see the doctor and they would refine everything.
