An optometrist will diagnose myopia with:
A refraction assessment test
An eye health [exam]
During the refraction assessment test the [eye_doctor] will put a mask-like device with wheel-like lenses of different magnifications in front of the patient’s eyes to see which combination of lenses helps the patient see most clearly.
For an eye health [exam], the [eye_doctor] may administer eye drops that dilate the pupils to allow a clear view to the back of the eye.
