We need to provide our organism with the necessary nutrients and vitamins to protect our sight as much as we can. This is the only way to keep our eyes healthy as we grow old.Our eyes have never been as exposed to all kinds of harmful elements like now. We work in front of a computer screen for hours and we spend most of our time watching the TV, reading or checking our mobile phones. The sight is one of our most important senses. Thanks to it, we can see objects, we have the ability orient ourselves and we can distinguish between light and dark. Each object is perceived differently depending on its brightness and color. On the other hand, the pupil reacts differently depending on the brightness and distance. The eyes and the elements that make them up, like the cornea, iris, pupil, eye nerve and retina need nutrients and vitamins in order to function properly. Any tiny disturbance can have serious consequences and deteriorate our eyes.
The causes of ocular diseases and the main defects of the sight
Causes of agingThe main causes of this premature aging can be due to working or reading without enough light. As we mentioned previously, subjecting our eyes to the radiation of screens from the computer or mobile phone will not help. Anyone who works with a computer will be more exposed. The first sign is when the eyes start to hurt. Moreover, the stress from work can also affect our ocular health. Other risk factor for our sight is working in places with a lot of dust or sand, as well as laboratories or industries with many chemical products. The smoke from tobacco also produces ocular fatigue and the UV rays from the sun, both in summer and winter, are harmful for the eyes. Sunlight emits UV rays that can damage the eyes and skin. It produces free radicals which damage the inside of the eyes. Moreover, the chlorine from the swimming pool also damages the eyes.
How to protect the eyes from the UV rays
Diagnosis and treatmentPeriodic sight tests are the best method thanks to their high efficacy to detect and treat eyes problems and ametropy in time (myopia, astigmatism and hypermetropia)
Vitamins and supplements for the health of our eyes
Vitamin AVitamin A plays a very important role by helping to protect our ocular health and the photoreceptor cells. The foods that contain vitamin A are beef liver, carrots, vegetables, potatoes, butter and egg yolk.
Vitamins C and EThey help to fight against the free radicals. We can find vitamin C in the following foods: parsley, cabbage, broccoli, citrus and peppers. Vitamin E is present in vegetable oils, walnuts, asparagus and kale.
CarotenoidsGroup A vitamins such as beta-carotene, lycopene, zeaxanthin and lutein.
PolyphenolsThey improve our sight. Some of the food sources are: cranberries, currants, maqui berries and grape seeds.
Omega 3 fatty acidsThey play a very important role when it comes to preventing diseases of the retina like ARMD and for the production of tears, which keep the eye moistened.
ZincIt is a very important mineral for our sight, since it is a powerful antioxidant. Zinc can help our body to absorb vitamin A and it protects our eyes against macular degeneration.
