Moscow: «Middle East» Ophthalmologists explain that vision, as a general rule, begins to weaken after a person reaches the age of forty, even if it was perfect before that. Explaining the seriousness of poor vision and how it can be combated.
Doctors explained that “presbyopia” is a condition in which the lens of the eye gradually expands with age and loses its flexibility, even though the mechanism causing the changes in its curvature and the muscles associated with it work normally. However, the lens itself becomes so dense that the person does not see close objects.
For this reason, doctors recommend wearing glasses to correct long-sightedness resulting from aging. The lens can also be replaced with an artificial lens through surgery, as the multifocal lens provides normal vision at any distance. This is according to what the Russia Today news network reported on Vesti. ru» local.
As for “age-related macular degeneration”; It is a common disease associated with changes that occur in the central area of the retina (macula), which contains many photoreceptors.
In macular degeneration of the retina, blood circulation is impaired, causing photoreceptors to suffer. As a result, a black spot appears in the center of the visual field. The first symptom of this disease is the distortion of the image of things.
The experts continued by saying that “cataracts” are an inevitable condition of aging of the lens. Because its size is constantly increasing, by the age of forty, the lens loses its elasticity, and at the age of sixty, it begins to lose transparency; In the early stages of cataracts, a person feels the presence of a veil in front of his eyes and what is called “black flies.” However, this problem can be eliminated by undergoing surgery to replace the natural lens with a transparent artificial lens.
As for glaucoma, it is a neurological disease that leads to complete blindness. It results from the failure of image transmission through the fibers of the optic nerve, which leads to a narrowing of the visual field. High pressure inside the eye is one of its symptoms.
In this context, consulting an ophthalmologist periodically and monitoring the level of pressure inside the eye allows for early diagnosis of the disease and treatment using medications, special drops, and a procedure using laser beams. In critical cases, surgery may be required to slow the progression of the disease and preserve vision for many years.
