How will an eye doctor perform eye examination without refraction?

How will an eye doctor perform eye examination without refraction?

Two different things: A comprehensive eye evaluation should include a refraction, but it is not always essential. Refraction measures whether the eye is near- or farsighted, or has astigmatism.
