The eyes are very sensitive to sunlight, especially in the summer months when the incidence of UV rays is higher. Sunglasses are the best protection to prevent possible damage to the eye surface. That is true, provided they meet minimum quality requirements.
CE Label
They must be homologous goggles. They must always show the CE mark. Unfortunately, counterfeiting has succeeded in copying this logo perfectly. And it is very difficult to distinguish between the European conformity marking or the China Export brand. The best way to make sure that these are not counterfeit or that they are not in breach of Community regulations is to buy them in one optics and to avoid selling by travelling or in unauthorised places.
Glass types
Glasses can be mineral or organic. You never have to buy glasses with plastic crystals that offer absolutely no protection against UV rays. Plastic contains absolutely no filter and can seriously damage the eyes.
The crystal color is not just an aesthetic element. It also affects vision. Green crystals change the tone of colors much more than grey crystals, for example.
Groar crystals have the advantage of giving much sharpness and largely avoiding reflections.
Filter Types
Most of the time, however, the lens label shows a numbering ranging from 0 to 4. Indicates the amount of light that the crystals are capable of absorbing. Crystals marked with 0 absorb 20% light while category 4 crystals absorb almost 90%. This must be taken into account, depending on the use we are going to give to the goggles. For example, if they are to be used for driving, category 4 goggles would not be recommended, as they may mislead us too much of the color of objects. Instead, they would be ideal for high-mountain activities where the incidence of UV rays is strongest. For everyday activities it is recommended to use category 1 or 2 goggles.
The importance of size
Size and shape are important. The bigger they are, the more they will protect us from solar rays. And the more locked and peeled on the face, the more we can protect ourselves from the entrance of external elements.
Polarised, yes or no?
Polarized goggles have their advantages and disadvantages. The polarization is a filter that is added to remove the reflections. But it has the disadvantage that we may not be able to see depending on mobile screens, cash machines, or television sets. They are ideal for outdoor sports, such as cycling, skiing, etc. as well as driving.
Wearing glasses in children
Very careful with children. No use of toy goggles. The crystalline of the under-12 years is completely transparent, so the penetration of the UV rays is greater and can have harmful consequences on vision.
To sum up, it is very important to use the right goggles for the activity we are going to do. They must always fulfil the necessary quality and safety guarantees. Note that the use of inappropriate goggles is more damaging to the eye than using goggles. Inadequate glasses can lead to severe conditions such as retinopathy, conjunctivitis, and even speed up the process of cataract formation.
From Clinic Ophthalmological TACIR we recommend the use of sun-eyes throughout the year, both in large and small, provided they meet the appropriate quality requirements.
