Ophthalmologists identify three key causes of vision loss after age 40
Ophthalmologists at the Svyatoslav Fyodorov Eye Microsurgery Clinic on Nikonova, 18, advise not to neglect eye health and invite Ural residents over 18 for an in-depth visual system examination with an ophthalmologist consultation at a special price — 2,950 rubles (approximately $33 at current rates) instead of 4,200 rubles (approximately $47 at current rates) according to the price list. To book an appointment, submit an application by February 2, 2026, and the discounted examination can be taken at a convenient time until February 23, 2026. The result of the in-depth ophthalmic diagnosis is a complete picture of your eye health, identified causes of poor vision, and treatment recommendations if necessary.
Our eye is a complex mechanism performing important functions. Light passes through natural lenses — the eye«s lens and cornea — the eye muscle is responsible for focusing on objects at different distances, the image is projected onto the retina and transmitted to the brain. After age 40, the lens gradually becomes denser, as well as less flexible and transparent, making it hard for the eye muscle to control focus on objects at varying distances, and near vision deteriorates. Therefore, most people with age begin to experience difficulties with reading, writing, and working on a computer.
«None of us can avoid this physiological process, nor slow it down. Age-related farsightedness — a decline in visual acuity after forty — is complained about even by those who previously had 100% vision,» says B.V. Romanenko.
Pathologies of the retina, which is responsible in our visual system for perceiving and transmitting images to the brain, are one of the causes of serious vision decline.
«It is recommended to regularly be examined by an ophthalmologist for general diseases that appear with age, especially chronic ones: diabetes, atherosclerosis, kidney, heart, and vascular diseases. They are detrimental to the retina,» says retinologist (a specialist in retinal diseases) V.V. Kislitsyn. «During an examination »on a wide pupil,« we sometimes see signs of high blood pressure, deposits on vessel walls due to atherosclerosis earlier than these diagnoses are established. In diabetes, due to excess sugar, blood vessels become fragile, which provokes hemorrhages in the retina. The effect of treatment is better the earlier the problem is detected.»
Cataract (clouding of the lens — the natural lens inside the eye) leads to a slow decline in vision, its speed is individual and depends on many factors: location of cloudiness, age, accompanying eye and general diseases of the patient. This process can take from several months to years. Without treatment, cataract leads to a noticeable decrease in activity and quality of life, and also contributes to the development of other eye diseases. For example, glaucoma — a chronic disease with an unfavorable prognosis. Without therapy, it leads to blindness.
