A member asked:

My 4 yrs old son's doctor manually used lense after lense in front of my son's eyes to test his eye sight. what is technical term for this method?

A doctor has provided 1 answer

None: This is simply, as you have described, manually comparing lenses to achieve the optimum correction. It is a method of trial and error usually using a trial frame. It can work well and is usually less threatening for a child than the device used for older children and adults called a phoropter.
