With time, all body parts get affected and deteriorate, and vision is no exception. He Ageing This causes a series of ophthalmological changes such as decreased ability to focus, sensitivity to light or dry eye, but in addition, there are also various diseases associated with age.
waterfalls
most of waterfalls These are related to age. Around the age of 40, the proteins in the lens begin to disintegrate and stick together. This congestion creates a cloudy area in the lens, called a cataract. Over time, cataracts get worse and a large area of the lens becomes cloudy.
Harvard experts explain that this clouding of the lens usually develops slowly over several years. it’s possible It doesn’t look cloudy Unless it blocks the central line of sight and thus affects vision.
eye disease
Over time, the anterior chamber of each eye may become shallow in some people. can cause contraction a blockage in drainage system Of aqueous humor near the iris. The resulting buildup of fluid can cause a sudden increase in pressure inside the eye that damages the optic nerve, a condition known as eye disease closed angle. If it is not treated it can cause blindness.
Another form of glaucoma is called open angle glaucoma, occurs when the pressure in the eye slowly increases due to a different problem: the slow outflow of aqueous humor through the trabecular meshwork. Like angle-closure glaucoma, the resulting accumulation of pressure inside the eye can damage the optic nerve, leading to blindness if left untreated.
macular degeneration
It is an eye disease that can cause blurred central vision and is one of the leading causes of vision loss in older adults., does not cause complete blindnessBut it can make it difficult to see faces, read, drive, or perform close tasks, such as cooking or fixing things around the house.
It occurs when aging damages the macula, the part of the retina that controls clear frontal vision.
diabetic retinopathy
Diabetes is a disease in which high blood sugar levels occur because the pancreas does not produce enough insulin or the body’s cells become resistant to insulin. In both cases, sugar can accumulate in the bloodstream and damage blood vessels And entire body parts including eyes.
diabetic retinopathy This occurs when the blood vessels that nourish the retina leak, causing swelling of the retina, or when new blood vessels form, causing retinal hemorrhage or detachment of the retina. If not treated on time, this condition can lead to blindness.
