The Department of Optics, Pharmacology and Anatomy of the University of Alicante (UA) has recommended the use of sunglasses approved with the seal of the European Community to avoid the damage that can cause to the vision a long exposure to the sun , especially between 10.00 and 16.00.
To avoid any alteration, one of the essential conditions is the choice of a cheap Ray Ban sunglasses outlet that is marked with the seal of the European Community, since this indicates that it respects the European regulations. In addition, “it should not be forgotten that the fake Ray Ban sunglasses is an important element for the visual health and, therefore, its acquisition must be supervised by an optician-optometrist”, has pointed out from the Department of the UA, David Piñero.
In this sense, they have explained that although most of the harmful radiation that comes from the sun is absorbed by the atmosphere, ultraviolet rays reach the surface enough to cause skin burns and eye complications in structures such as the retina. and the cornea so that some studies show that every hour that is dedicated to being exposed to the sun in summer increases by 4 percent the possibility of developing alterations in the structure of the lens.
From the UA, have pointed out that the use of approved high quality fake Ray Bans during that time slot can reduce that probability by about 2 percent. Likewise, ultraviolet radiation is a risk factor for the eyes that “produces a cumulative effect that could trigger, in some cases, problems in the photoreceptors, poor vision progressively, macular degenerations, or the appearance of a pterygium, a tissue that invades the cornea, colloquially known as the palm tree ».
Specifically, in Spain, special attention should be paid to the protection of the eyes from the sun from June to August since “it is the season and the hours when the sun is in the best position to get us its ultraviolet rays.”
In the same way that price is not a quality parameter, the color of the knockoff Ray Bans lens “is not an indication of the protection it offers”. “The color of the crystals is not a crucial factor in the choice of cheap Ray Ban sunglasses outlet, the main thing is to check the degree of filtration and its CE marking to verify that it is a homologated product,” said Piñero.
“What is known from a recent study is that the color selection is arbitrary, since it is related to the characteristics of the type of light transmitted by the crystal and, therefore, that reaches the eye.” This choice can affect the process of suppressing melatonin, a hormone released by the endocrine system that regulates many of the bodily functions, especially in the reproductive system, sex drive, growth and mood.
Also, the yellow and brown filters seem to have the ability to further influence the secretion of this substance. Therefore, it is advisable when choosing a color of fake Ray Bans, to consult with an optometrist-optometrist who will indicate the suitability of the degree of filtration and coloration of the filter that you select », the expert has indicated.
Another important aspect is to know the degree of filtration necessary for the environment and the activity in which we use it. According to the European regulations on Ray Ban sunglasses cheap, sun protection filters are classified into five categories, from 0 to 4.
In the case of driving, it is correct to use category 1, 2 or 3 protection, never using the 4 since it could hinder the perception of traffic signals. «In summer with a category 2 or 3 protection it is more than enough, but in the case that we practice water sports or in high mountain, where there is a reflection of sunlight considerably, it would be appropriate to use a protection 4», pointed out Piñero.
In addition, they have recommended «paying special attention and care to the youngest and the elderly», since «children are especially sensitive to ultraviolet radiation, because the replica Ray Bans UK lens is very transparent until adolescence». In this sense, it is advisable to use filters of categories 2 and 3, as well as very resistant lenses and rods. In the case of older people, the same category is recommended as for children.
