Why not protect our eyes from the sun? The most common mistakes and myths about sunglasses



[ad_1]

Nowadays, sunglasses have become an integral part of the style, but seldom perform their true function – protection. Many people remember to protect their skin from the sun, but often eye protection is forgotten. Visual experts note that nowadays there are a growing number of people facing problems and even dangerous eye diseases caused by UV rays. How and why it is important to choose sunglasses is recommended by optometrist Božena Kuftin.

When choosing sunglasses, people tend to consider only a few criteria: style and price. However, as the goggles protect the eyes – it is not properly evaluated. There is little talk about dangerous eye diseases, which are becoming more common at younger age.

"People spend a lot of time in the sun – they get used to it, they spend time at the seashore and there's still relatively little talk about the damage caused by UV rays in their eyes." We know enough about the damage caused by UV rays on the skin, so high quality sun creams have become quite common for everyone who is on vacation or spending time in the hot summer sun. But how are our eyes? The only and best protection for them is still the sunglasses, but that does not mean that any sunglasses can protect the eyes properly, on the contrary – the wrong choice of sunglasses can not only protect the eyes but also harm them " , – says the optometrist.

Wearing glasses with shiny lenses on the seashore and in the mountains does not make sense because they will not protect you properly.

UV rays and eye diseases caused by them

Anatomically, the eyes themselves are not able to protect themselves from harmful UV radiation and need additional protection of high quality. A high dose of UV light, such as the skin, can burn in a few hours, that is. and. damage sensitive parts in them.

"If we look at the effects of the sun on the skin, we will also find the positive side, such as vitamin D, that we receive in direct sunlight, but the effect of UV rays on the eyes has no beneficial effect, but only damages. modern studies suggest that various forms of ocular tumors may be associated with long-term chronic exposure to UV radiation. Diseases such as cataracts, keratitis, conjunctivitis, photoceratitis and ocular melanoma are becoming increasingly common at younger ages, "says Kuftin.

The most dangerous eye disease is cataract, which was not detected in time and causes blindness when left untreated. It is typical for the elderly but, according to the World Health Organization, up to 20% of the population is older. Cases of cataracts can lead to excessive UV radiation.

Better without glasses than inadequate

Today, we can find sunglasses in almost every store – the offer is really huge and prices start at just a few euros. This is especially true for a young person, so most people choose sunglasses to focus on in price and style. However, these glasses rarely have adequate protection against UV rays because they are without an ultraviolet filter.

"Often, sunglasses have UV-marking, but they rarely have quality-compliant certificates, so they do not guarantee protection. It pays to look for UV-400 (or 380), UV100 percent on eyeglass frames or packing. or CE lacquered. Goggles marked in this way meet medical requirements and protect against UV rays. If it is written that the lenses do not pass through the beam at 380 nm, this means that the eyes will be well protected and, if less, the protection will be incomplete, "said Kuftin.

On the other hand, an optometrist ensures that you look for the best quality sunglasses in special optics.

"Optical centers must have special certificates, claiming that the sunglasses they sell meet the essential safety requirements of the European Union," says Kuftin.

When choosing eyeglasses, an optometrist advises to look at the categories of eyeglass lenses and there are four. For example, Category 1 is a totally transparent lens that does not absorb light, and 4 is a highly colored lens for people with special needs. According to Kuftin, in this case it is important to choose the correct ones. Wearing glasses with shiny lenses on the beach and mountains does not make sense as they will not protect properly, and hiding under Category 4 goggles in the city is still dangerous – injuries can be caused due to poor visibility. For everyday use, Lithuanians are best suited for sunglasses 2 and 3.

Who needs more sunglasses?

According to an optometrist, one of the most common myths in their practice is that people with visual impairments can not wear sunglasses.

"I hear this quite often when I meet clients, especially those with low vision and wearing corrective glasses every day. These people need sun protection because their eyes are no longer healthy, some are still sensitive to light. Therefore, they need to look very carefully with their eyes. Even those who can not wear contact lenses have a choice. For example, optics can produce sunglasses with diopters that will serve both to drive a car and to spend time on the lake. That's why the choices are always there, "says Kuftin.

Another group of people who care about sun protection are children. During the summer, all mothers ensure their children come out with covers that protect the head from overheating, and few forget the strong sunscreen that protects the skin from harmful UV rays. However, children rarely buy sunglasses.

"This is because the prevailing view in society is that goggles are not a necessity, they are a detail of the style and who is the detail of a small child because it only disturbs?" Although the reality is different. Children's eyes are the most sensitive to the sun. Some babies are born without irises, only with their incubation or a small part. They have only large pupils in their eyes, they look almost black. The eyes are shining against the sunlight, so that it does not light the retina, so it moves, flies. For these children, sunglasses are required. In addition, the sun is allergic to the eyes of some children. They are afraid of redness, redness and allergic keratoconjunctivitis. Eyelashes can grow and their secretion increases. The child wants to squint, rubbing his eyes, "said the specialist.

Therefore, it is very important to watch your child as their eyes react to the sun and even when everything seems to be good – still consult ophthalmologists. They will recommend the most suitable and convenient option for your child. Nowadays, the range of sunglasses is excellent – the optics are filled with durable, soft sunglasses with special ropes on which the glasses hang, so the child does not miss them. They do not interfere with active movement and do not restrict the child.
