Eye blinks do not return to normal at age 48.
Presbyopia is a physiologic degenerative condition that results in a decrease in accommodation amplitude measurements with age. That’s why presbyopia can’t return to normal at age 48.
Presbyopia is a condition that usually occurs around the age of 40 and above, with a decline in the eye’s ability to regulate, leading to difficulty in seeing near, blurred vision that was not present before, or eye pain after seeing near for a long period of time. There may be symptoms of visual fatigue such as soreness and swelling of the eyes, tearing, and heaviness of the eyelids.
Presbyopia is a physiological phenomenon that occurs in everyone, and generally stabilizes by the age of 55-60. It can be corrected by optical means, and currently the most convenient and stable way of correction is frame glasses.
It is recommended that patients go to the hospital for optometry and prescription of glasses to correct presbyopia.
