What are the best sunglasses on the market?
A type of glasses very common, especially during holidays, are sunglasses. Its use is very popular in people of all ages, although the use is not always the most appropriate. You have to take into account some essential features when buying them and we hope that this guide to buying the best sunglasses will help you when choosing them so that you make a good investment, but above all, to avoid damage to your eyes.
The first consideration you should take into account when choosing which sunglasses are better is that they are certified with the CE seal, which guarantees that they meet the minimum standards to provide you, satisfactorily, a vision with maximum eye protection.
Ultraviolet or UV rays, are part of the sun’s rays and not only affect the skin, but also the eyes, so, an essential feature for sunglasses is that they have a UV filter. This is a protective layer, made with chemicals called chromophores, which are able to attract energy or light. It is added to the lens material during processing so that it can absorb UV radiation.
The adequate UV protection is not determined by the color of the lens, as it tends to be mistakenly believed. Keep this in mind when comparing sunglasses and especially when buying cheap sunglasses, because in the market there are many sunglasses that do not protect your eyes properly and could cause irreversible damage to your retina.
Another fundamental aspect is that the lenses have a sunscreen to prevent the rest of the solar radiation from damaging the eye. This filter is determined by the color of the lens and its absorption capacity.
Brown is recommended especially for winter sports, in cases of myopia or if artificial light is used since it greatly improves the vision of the contrasts. Gray is the best alternative for sunglasses to drive because it does not alter the vision of colors. Green adjusts well to any use since it scarcely alters the perception of color. Yellow is recommended for night driving because it relieves the vision of contrasts.
Sunglass lenses are made of glass, plastic or polycarbonate materials, but they can affect vision and quality if they are not properly coated. They can also be elaborated with formulas of optical correction, with which you can enjoy and protect yourself in the open air while maintaining an adequate vision.
Glass or glass lenses offer a clear view, but they are a little heavier, in relation to plastic or polycarbonate lenses. Plastic lenses are lightweight and very durable, but they can be prone to scratches. The polycarbonate lenses are extremely durable, resistant and light, which is perfect for use by children and sports activities.
There are other added features that surely influence how much sunglasses cost, but you should always make sure that the lenses have at least UV protection and sunscreen, to adequately protect your vision.
The polarized sunglasses neutralize the reflected light, giving sharpness and contrast. They block the uncomfortable glare of the sun on the bonnet of cars and pavement, over water or snow, so they are useful when driving, sailing or fishing. They have the disadvantage that they hinder the correct reading of the LCD screens of mobile phones and ATMs. They do not control the absorption of UV rays, but they can be combined with chemicals that do block them.
The photochromic lenses are lightened or darkened, in a matter of minutes, depending on the amount of light present, so that they can be used both indoors and outdoors. The photochromic treatment can also be applied to the vision correction and sun lenses, so it offers the advantage of not having to change glasses during the day.
