Even if your vision was perfect all your life, then after 40 years changes can begin.. Suddenly, it turns out that one has to squint, in the dark it became difficult to distinguish faces, and the letters in the daily newspaper became suspiciously small and merge.
After 40 years, it is worth signing up for a routine examination by an ophthalmologist, even if you have never used glasses or contact lenses.. A specialist is needed to find out if you have a risk of AMD (age-related macular degeneration - “retinal aging”) or glaucoma, t. these phenomena often occur after 40 years1. But, if you “catch” them at an early stage, you can slow down the progression of these conditions and save your vision..
However, not everything is so dramatic, because not every age change is so serious as to threaten eyesight, although annoying and inconvenient.
Dry eyes.
This problem most often occurs in a dry climate / room (ex.. office) and after a long work at the computer. Usually, people blink about 30 times per minute, but while working at a computer, the blinking frequency drops to 10-15 times per minute.. In women, dry eyes may be associated with changes in the level of sex hormones, and taking contraceptives..
What to do?.
The condition is well treatable: consult an ophthalmologist to recommend moisturizing drops that restore the tear film. However, do not buy drugs that reduce eye redness..
They constrict blood vessels, thereby causing even greater dryness.. It is also important to adjust the diet - drink more water, reduce the amount of alcohol.
Near vision loss.
If you need more light to see the letters in the book or you notice that you keep your smartphone farther from your eyes to read SMS, then this is most likely an age-related presbyopia or hyperopia. It is not dangerous, with age the lens inside the eye loses its elasticity, therefore the vision is disturbed..
What to do?.
Visit the doctor for discharge points. According to the prescription, inexpensive standard reading glasses can be purchased in optics, but individual selection is also possible..
Instead of old-fashioned bifocal glasses, glasses with multifocal lenses should be purchased.. They allow you to see objects at different distances, instead of using ordinary glasses each time you need to read the menu or see the message on the screen.
Glaucoma.
This increases the pressure in the eye.. The condition is dangerous, as it causes damage to the optic nerve, without treatment, loss of vision occurs.
It usually begins with a deterioration of peripheral vision, there may be bouts of pain in the eyes, their redness.
What to do?.
After 40 years pass annual inspection. The doctor will measure intraocular pressure, and also expand the pupil to determine true visual acuity and retinal examination. With early detection, glaucoma is treatable..
Cataract.
So called clouding of the lens. The lens consists of water and protein structures, with age, the protein changes its properties and becomes cloudy. As a result, vision becomes blurred, blurry, night vision deteriorates..
What to do?.
Wear sunglasses, as ultraviolet rays can exacerbate the condition. In the early stages, glasses will help, but in more severe cases, the lens is replaced with an artificial lens..
Macular degeneration (macular dystrophy, macular degeneration).
The macula or macula is the thinnest part of the retina, consisting of millions of photosensitive cells that provide visual acuity.
When the macula is destroyed due to the formation of drusen in the form of yellow spots (accumulation of lipofuscin - the hormone of aging), central vision begins to blur.. The reason is considered a lack of carotenoids: lutein and zeaxanthin, as well as vitamins - antioxidants, zinc and selenium.
What to do?.
Since our body does not synthesize carotenoids and vitamins on its own, but receives them only from the outside, through food, you should include in your diet foods such as carrots, orange, walnuts, red pepper, or use a vitamin-mineral complex every day to support visual acuity.
