The risks of the sun on the skin are known to all but many do not know that even the eyes can be damaged by exposure to UVA and UVB rays. In particular, the excess of UV damages part of the ocular lens to the point of causing rather serious damage. You may be interested in the article "How to protect yourself from the sun"
We must therefore be aware of the risks to which we expose our eyes when we sunbathe or do a tanning lamp so as to protect them adequately
How to protect your eyes from the sun, useful recommendations
When our eyes are exposed to the sun or to a tanning lamp, it is essential to wear sunglasses with filters in accordance with the law, preferably enveloping so as to protect the eyes even from harmful lateral rays.
We recommend that you buy glasses exclusively in specialized stores, so as to be sure that you have chosen a product certified according to the directives of the European Community: they must have the CE mark. Pay close attention to the fake product; the Chinese copied the CE mark in a perfectly identical way. It is very difficult to distinguish them, you have to pay attention to a single detail, that is the distance between the letters: the European trademark has more space between the letters, while the Chinese one has an almost zero space between the two letters.
As we have already mentioned, compliant glasses are recognizable by the CE mark, not to be confused with the China Export mark, a trick used to import non-compliant glasses. The difference, as you can see in the photo above, is only in the distance between the letters C and E.
The glasses must be accompanied by a booklet indicating the degree of protection from UV which ranges from 1 to 5.
To go to the sea or to the mountains, grade 3 is recommended, but if you go skiing on the glacier you need a level 5 filter.
How to protect the eyes from the sun, children and the elderly
Children and the elderly are the most sensitive and at risk. For children under the age of ten, it is essential to choose good lenses. Even for the elderly, the choice of sunglasses is essential since their tearing is scarcer, the lens more opaque and there is a greater predisposition to maculopathy.
Even if you are in the shade, you must wear glasses; don't forget that the UV rays are reflected by the sea, sand, snow or concrete.
Even if there are clouds, you need to protect yourself, know that as many as 80% of the rays filter through undisturbed.
If you go trekking or go to the high mountains, buy wraparound glasses with suitable lenses.
How to protect the eyes with food
The eyes also benefit if we look after our diet. In detail some suggestions.
- Consume a lot of fruit especially blueberries, oranges, kiwis and apricots and vegetables such as carrots, peppers, tomatoes, green leafy vegetables
- Avoid fats
- Eat fish and foods rich in omega-3 and omega-6 at least twice a week: these fatty acids increase antioxidant substances and therefore defend the macula
- Take lutein, a yellow pigment found in many vegetables, fruit, wheat and even egg yolk. You can also opt for lutein-based supplements
- Drink plenty of water, even the eye can suffer from dehydration and the one who pays the consequences is above all the vitreous body, the gelatinous liquid that fills the eyeball
- Those suffering from retinal dystrophies cannot absolutely neglect multivitamin complexes containing vitamins A, C and E, selenium, zinc and lutein, for those suffering from retinal dystrophies
What to do if you wear contact lenses
It should be noted that contact lenses must be removed and replaced with glasses to avoid redness caused by the sun, glare, etc., but if you can't do without them, here's how to behave.
- Avoid falling asleep in the sun
- Avoid getting sand in your eyes
- Often use artificial tears because the eye in summer tends to dry out more
- Swim in the sea without contact lenses; if you really have to do it with the lenses, wear goggles and put them in the liquid immediately after the bath to prevent salt from settling and to disinfect them
- Use daily contact lenses to decrease the chance of infection especially if you are unable to clean them daily
- Always carry eyeglasses with you to be able to remove them in case of discomfort or red eye
- Use sun contact lenses with a wide coverage of ultraviolet rays as well.
Even in fresh water the lenses must be removed, as there could be a microorganism dangerous for the cornea, Acanthamoeba, which normally does not penetrate the surface of the eye, while the microtraumas caused by the lens could facilitate the onset of infection and cause keratitis.
