How to optometry for presbyopic eyes

The methods of presbyopic optometry mainly include natural pupil method, mydriatic optometry, autorefractor, etc.

1. Natural pupil method The examinee will

understand the refraction by observing the size and reaction of the pupil without using any drugs.

2. Mydriatic optometry The examinee

will dilate the pupil through mydriatic drugs, and then observe the movement and reaction of the eyeball to determine the degree of refraction of the eye. Such methods are more accurate.

3. Autorefractor The

examinee will use autorefractor to measure the refractive power and corneal curvature of the eyeball, which can obtain accurate examination results.
