Causes and solutions for visual impairment after 40 years of age?

Ophthalmologists point out that, as a general rule, vision starts to deteriorate after the age of 40, even if it was excellent before.

Presbyopia is an age-related vision problem that mostly occurs in people over 40 years of age, Sarkh al-Awsat reported, citing RT news agency.

Presbyopia is a condition in which the lens of the eye gradually widens with age and loses its elasticity.

For this reason, doctors recommend wearing glasses to correct the nearsightedness that occurs with aging.

You may also be fitted with a multifocal lens, an intraocular lens that has the ability to show both near and far.

Age-related macular degeneration (yellow spot disease) is a common disease associated with changes in the central region of the retina (macula), which contains many photoreceptors.

In macular degeneration of the retina, blood circulation is impaired and photoreceptors are damaged.

As a result, darkening appears in the center of the visual field. The first symptom of this disease is a distortion of the image of the object.

According to experts, a cataract is a clouding of the lens.

By the age of 40, the lens loses its elasticity and by the age of 60 it starts to lose its transparency.

In the early stages of cataracts, a person can feel the presence of a veil in front of their eyes and the presence of so-called ‘black flies’.

However, this problem can be eliminated with surgery, by replacing the natural lens with a transparent artificial lens.

Glaucoma (eye pressure) is a disease that causes blindness by damaging the optic nerve.

It is caused by the image not being transmitted through the optic nerve fibers, leading to a narrowing of the visual field.

In this regard, periodic consultation with an ophthalmologist and monitoring of the level of intraocular pressure allows for early diagnosis of the disease and its treatment using medications, special drops and laser beams.

In critical cases, surgery may be needed to slow the progression of the disease and preserve vision for many years.
