Presbyopia is a physiologic degenerative disease that is common in middle-aged and elderly people. Measurement of presbyopia needs to go to the hospital for optometry. Presbyopia degree is composed of two parts, i.e., the sum of optometry degree and physiological degree, which is derived from the examination in the hospital. Physiological prescription is estimated according to the age of the person, but generally from the age of 40 years and beyond the beginning of the physiological prescription, increasing year by year. Presbyopia is a degenerative disease of the eye, which cannot be treated so far. However, patients should avoid eye fatigue and go to the hospital in time for a detailed examination before wearing glasses with the right prescription.
