Presbyopia increases with age and is a normal physiological phenomenon, not due to the wearing of presbyopes. With age, the elasticity of the lens gradually decreases, and the refractive ability of the lens weakens, resulting in presbyopia. Normal people will gradually develop presbyopia after the age of 40. It is necessary to wear presbyopia glasses with appropriate prescription. Presbyopic lenses are good for clear vision and avoid visual fatigue caused by normal eye use. If you choose the degree does not match the presbyopia glasses, not only will increase the fatigue of the state, and even aggravate presbyopia. Normally, we should pay attention not to read books and electronic products for a long time, and do outdoor exercise moderately. It is recommended to have a routine vision checkup once a year, and if you find that your glasses are not the right prescription, you should correct it in time.
