The sense of sight is decisive for a person to have a good quality of life. Taking care of the health of the eyes is key, since around 50% of the information that people receive from their environment comes through them, says the Clínica Baviera, from Spain.
This institution indicates that half of the brain activity is dedicated to processing the images that the individual captures of realityin addition to the fact that the bulk of the sensory experiences that people have are visual.
These are compelling reasons for people to work in search of optimal visual health, since the appearance of diseases can cause serious damage not only to these organs, but also to people’s daily lives.
Here are some tips that can help in this purpose:
Consume vitamin A
One way to take care of the eyes is by consuming vitamin A, which is key for the proper functioning of the retina and especially for night vision or in low light.
This vitamin is found in two forms in food: retinol, which is the active form of vitamin A and is present in foods of animal origin such as liver or whole milk; and, carotenoids, which are dark-colored pigments present in foods of plant origin and, once ingested, the body is capable of transforming them into their active form of vitamin A.
One of the foods that contains the most vitamin A is the carrot. This vegetable is rich in beta-carotene or provitamin A. According to the Body Mind portal, “a 100-gram serving of it covers 110% of the vitamin A that a person requires per day.”
Eggs, sweet potatoes and pumpkins are also rich in this vitamin.
Give up smoking
“Cigarette smoke, as well as all the toxins it contains, are harmful to all parts of our body,” says Sunir J. Garg, an eye doctor and professor of ophthalmology at Thomas Jefferson University in a publication of the digital medium Business Insider.
According to the expert, smoking can damage the retina and cause macular degeneration, a condition that can make vision blur or create dark spots.
This is because smoking can reduce the amount of oxygen reaching the retina and damage the tiny blood vessels in the eye.
When a person is exposed to the sun without wearing glasses, the eyes are exposed to high levels of ultraviolet (UV) light.
According to Business Insider this can damage the cornea, which is the clear layer of tissue over your pupil. However, it is important to use the right sunglasses because not all of them filter ultraviolet light and sometimes wearing sunglasses without a filter can be worse than not having them.
Regulating blood sugar levels and managing diabetes is key to maintaining eye health. According to the US Centers for Disease Control and Prevention (CDC), over time Diabetes can cause damage to the eyes, leading to vision loss and even blindness.
“Eye diseases that can affect people with diabetes include diabetic retinopathy, macular edema (which often co-occurs with diabetic retinopathy), cataracts, and glaucoma. All of these can cause vision loss, but early diagnosis and treatment can go a long way toward protecting your vision,” the CDC says. For this reason, keeping glucose under control is key to taking care of your vision. This can be achieved with a healthy diet and regular exercise.
Learning techniques to relax your eyes, especially after long work or study days, is key to protecting the health of your eyes, indicates the Clínica Baviera. The idea of any technique is to relieve visual fatigue and reduce the tension that accumulates in the muscles of the eye apparatus.
In this sense, the focus change techniques are some of the most recommended by specialists. You can focus on a distant object for a few seconds and then, very slowly, refocus your eyes on a nearby one, this helps to relax and rest your eyes.
