What are the ways to prevent difficulties in reading small letters and color recognition?

Difficulties in reading small print and color discrimination are most often seen in the early stages of alcoholic amblyopia, an initial condition that typically progresses over days to weeks to a loss of visual sensitivity in both eyes, seen in chronic alcoholics, and is a specific visual impairment seen in patients with chronic alcoholism. The disease is a lesion of retrobulbar optic neuritis with involvement of macular optic disc fibers. Pathology reveals symmetrical myelin loss of the central fibers of the optic nerve on both sides and loss of retinal ganglion cells, and is more severe in the macula, and in severe cases the optic nerve fibers may be replaced by collagenous connective tissue. Progressive vision loss or blurred vision is the main manifestation of this disease. The vision loss may progress gradually over weeks to months. Initial symptoms in patients are difficulty reading small print and discriminating colors, which gradually progresses to decreased visual sensitivity and blurred vision over days to weeks and usually does not progress to total blindness, although some patients progress rapidly and suddenly develop total blindness after a single episode of heavy alcohol consumption. The vision loss may be unilateral or may involve both eyes. Wearing glasses cannot make vision improve. 1, Do not read in direct sunlight or in the dark, do not lie down, lie on your back or read while walking or riding in a car. 2.You must pay attention to personal eye hygiene and keep the area around your eyes clean. 3, pay attention to diet and nutrition, eat more food containing vitamin A, such as goat liver, pig liver, eggs, milk, carrots, vegetables, etc. Promote outdoor activity rest and frequent far-seeing, 3-4 times a day, at least five to ten minutes each time. 4.Don’t be partial and picky about food and don’t eat too much sugar. 5.Prevent excessive eye use, do not work at close range for more than 50 minutes at a time, and take a 10-minute break every hour to relax the regulation of extreme vision, which can prevent myopia. 6, when doing homework in class to blink often, when you feel eye fatigue, you should close your eyes for half a minute, but do not rub your eyes, this will help to prevent myopia.
