Can anyone see me this answer.... please

Answer 1

listen when cilliary muscles are full relaxed the focal length increase that is said that we ars seeing at infinity. but whrn cilliary muscles are fully contracted then focal length becomes minimum that is 25 cm

normal eye range is from 25-infinity
