5 tips for having good eyesight for longer



Over time, the eyes become more prone to certain pathologist. By following these tips, you increase your chances of keeping good eyesight for longer.


WE GIVE UP CIGARETTES

Eye diseases have an important genetic component, but other factors play a role, including tobacco. "Smokers are four to six times more likely to develop AMD as they age,"  By an ophthalmologist and specialist in this degenerative age-related disease of the retina. It is characterized by the appearance of an increasingly large black spot in the center of vision, caused by the destruction of cells in the middle of the retina. This phenomenon is accelerated by tobacco, via the formation of free radicals. Cigarette smoke also precipitates aging of the lens. It loses its transparency, the vision becomes blurred: it is cataract.

WE ADOPT AN ANTI-AGING DIET

A diet rich in saturated fats and sugars damages the cardiovascular system, but also the vessels that supply the eye. "On the other hand, antioxidants and omega 3 have demonstrated a protective effect for the eyes", notes P rSouied. Among the substances studied, there are notably lutein and zeaxanthin: two carotenoids present in the macula, this area of the retina which is damaged with AMD. "They protect the retina from free radicals and from light," explains Éric Souied. Where to find it? In cabbage, spinach, pumpkins ... We also don't forget the other antioxidant vitamins and minerals, like vitamins C (peppers, guavas, kiwis) and E (almonds, hazelnuts, wheat germ oil) , zinc (oysters, lentils, eggs) and copper (nuts, seeds, algae).

WE LIMIT EXPOSURE TO SCREENS

Several studies have accused blue light from LEDs of being, in very high doses, toxic to the retina. These light-emitting diodes are present in certain lights, in the screens of Smartphones and tablets, but also in more and more computers. However, the conclusions to be drawn from it are not clear: "It is only a precautionary principle, because the conditions of experimentation have nothing to do with reality, specifies P rGilles Renard, scientific adviser of the French Society of Ophthalmology. If a problem should appear, it will not be before thirty or forty years of high dose exposure (six to eight hours a day). »What about blue anti-light glasses? Ophthalmologists recognize that they are not very effective. "They filter out very little problematic waves," says Professor Renard. It is better to reduce the time spent in front of the screens, especially those of Smartphones.

This is particularly true for children and adolescents, whose eyes are more fragile and who will have been exposed longer in their lives.

WE PROTECT OURSELVES (A LITTLE) FROM THE LIGHT

Admittedly, UV rays are harmful to the eye at very high doses ... but not everyone is concerned. For P r Souied, wear sunglasses all year round if you live in Paris or Lille is useless unless it is a matter of comfort. "Outside of summer, protecting yourself is especially necessary for people who work outside or live in regions where the sun is very strong, like the West Indies," By ophthalmologist. In this case, the reflex is simple: wear glasses of an index 3 or 4, including when the sun is cloudy.

WE DON'T SKIP SCREENING

If the cataract is treated easily enough, diseases like AMD or glaucoma, damage to the optic nerve, must be detected as soon as possible so that we can stop or slow their progression. "When there are symptoms, it is because the disease is already very advanced," . The right rhythm: an appointment with the ophthalmologist every three years, then every two years from the age of 45.
