Which sunglasses protect the eye?
Imagine you are in a seaside resort, strolling along the boardwalk and see a stand with sunglasses. We try them on, we want to buy them for ourselves. What we need to pay attention to tion?
We need to see if they contain a UV filter. When we wear tinted sunglasses, it causes our pupils to dilate because less light enters the eye, and we need to see clearly. More UV radiation enters through such a dilated pupil, if glasses have no filter. Horn diseases are emerging ki, lenses, for example, premature cataracts. Retinal diseases ki, including macular degeneration ¿ age-related glare.
There are studies showing that UV radiation accelerates the development of j this disease. So we can say that it accelerates the aging of the eye. When the filter is present, we prevent this effect.
When buying eyeglasses, as to which which we are not sure that they contain a UV filter, we bring ourselves more harm than good?
Yes. Many people think that sunglasses always help because less sunlight reaches the eye, but this is a misconception.
Should sunglasses have a certain shape, color?
The larger the surface of the lens, the better the protection. However, I would not pay attention to the color here, but to the strength of the UV filter and the degree of darkening. However, we need to know in which situations we will use glasses. If we are to use them while driving, we must not overdo the intensity of the tinting, because we will not see much on the roadway, especially lnie p In the late afternoon or in the evening r, when the sun is still shining, but it is not as bright as during the day.
But as we walk down that boardwalk and look at the sunglasses on the rack, we don’t really know if they have a UV filter or not, not m already talking about its power…
Therefore, a visit to an optical salon, is the safest way to b buying eyeglasses sunglasses. At the optician we have proven suppliers, tested glasses.
In salons and specialty stores you can buy also more expensive polarized glasses. I recently tried them on and actually saw a little better in them, despite the very harsh sunshine. What an invention?
Such glasses, in addition to UV filter, have a coating that reduces the occurrence of glare. This is noticeable, for example, on a lake or the sea, when we are on a boat and the sun reflects off the surface of the water. With polarized eyeglasses, these glares are smaller and less bothersome to our eyes. Such a solution is useful Also while driving, when the sun reflects off the windshields of other vehicles .
That is, it is worth investing in such glasses if we go on vacation to a place where this light is especially lnie much?
Where it reflects off sand or water, glass, bright buildings .
And people with visual impairment, what they should do?
I would advise wearing glasses sunscreen and contact lenses, which re themselves contain a UV filter, so they are additional protection for the eyes. Glasses are not always able to protect us from radiation from all sides, because from the side, sunlight reaches the eye.
That is, if someone usually wears sunglasses, but has the option of wearing lenses, they should take advantage of this option?
Yes, definitely, the eyes will be in this way b more comprehensively protected.
Not all people who re have a visual impairment can wear lenses. How to help them c protect your eyes from the sun?
An optician can prepare corrective sunglasses and we can use Also photochromatic glasses, i.e. those that re under the influence of light, they change color, darken. In this case, it all depends on private preferences, each person must decide for himself who ra option is best for him.
We bought glasses, they have a filter, they are dark, but still at the end of the day the eyes tear, they burn. It happens on vacations, especially ln warm countries. What to do then?
If we have to deal with dry air, wind, which re accelerate the evaporation of tears, it is worth having some moisturizing drops on hand, the so-called artificial tears. It’s worth buying ones that re do not contain preservatives harmful to the eye .
On vacation, it also happens that when we take off our glasses for a moment on the beach, sand falls into our eyes. They then need to be rinsed thoroughly, preferably with a saline solution, and carefully examined to see if under the eyelids, within the cornea ki, hard ki, there is no foreign body. If, despite several flushes, you still feel something, your eye hurts, you need to go to a specialist.
