Specialists at the German "Eye" Foundation have warned of the dangers of ultraviolet rays to the eye;
It increases the risk of developing keratoconjunctivitis, and in the worst cases, it can damage the cells of the retina, causing cataracts (cataracts) or cancer.
To avoid these serious risks, the Foundation stressed the need to wear sunglasses that provide good protection from UV rays up to the wavelength of 400 nanometers, which can be inferred by the UV400 label.
It is also important that the sunglasses have wide arms to protect against scattered light, which falls from the side.
The Foundation indicated that the color of the glasses' lenses may cause a change in colors in the surrounding environment, explaining that brown, gray and green lenses are the least lenses that change colors.
Yellow or orange lenses increase color contrast and have a relatively low dazzle protection.
The orange lenses are suitable for outdoor sports;
They enhance the contrast of green, but result in striking colors such as those of traffic lights not being perceived correctly.
It is important that the sunglasses are of a suitable size so that the nose pads or the arms do not put pressure on the face.
It is also preferable that the nose pads are made of soft plastic material, in order to flexibly adapt to the shape of the nose.
On the other hand, the Foundation stressed the importance of sunglasses for children in particular;
Because their pupils are larger than that of adults, and the lenses of their eyes also transmit more light;
So they inevitably need sunglasses that offer 100% UV protection on sunny summer days.
• It is important that the sunglasses have wide arms to protect against diffused light, which falls from the side.
• Children also inevitably need sunglasses that provide 100% UV protection.
wearing comfort
German specialists explained that the appropriate sunglasses for the eyes of the child should cover the eyes completely;
Therefore, it is important that the lenses be large enough to reach the eyebrow and to the edge of the face from the side to prevent the light from falling on the eye from the side.
It is important that the color of the lenses be dark, such as brown and black.
Sunglasses should also provide good protection against glare of at least Category 2 and good protection against harmful UV rays, UV 400. Sunglasses should have an appropriate fit for comfort and be unbreakable, so as not to injure the child's eyes .
