It is necessary to be provided with the necessary material not to put in risk the health. However, sports glasses are not always given the importance they deserve. As optician-optometrist Helena Rubio, manager and co-founder of the sports optician LensSport, explains, along with Isabel Prieto, both specialists in sports visual health, “sports glasses should be an essential part of the sports equipment that every sportsman should always wear when practising any physical activity, since the function of these is, on the one hand, protection against any impact and, on the other, protection against UV rays, insects, a branch that we can find on the road, dust, sand, stones that jump from the asphalt or the earth itself if we practice mountain sports…”?
Therefore, the use of a technical goggle has as its first objective the prevention of possible eye injuries caused by a blow, shock, fall, or by the radiation of the sun. And it is that one of these accidents could even produce problems in the cornea, internal haemorrhages, traumatic cataracts, or an inflammation both in the eye and in the area that surrounds it.
What sports glasses look like
There are as many sports glasses as there are sports and people use them for their practice. Normally, it is the sportsmen and women who practice outdoor activities who usually wear technical sports glasses, as they are the ones who are most at risk of suffering a problem, be it, for example, an impact from a rival player, a fortuitous fall, or the action of the sun.
However, it is activities such as triathlon, trail running, running, cycling or golf that are most often associated with the use of special lenses, to which more classic sports such as football or basketball are also added. Experts say that between 90% and 100% of eye problems caused by a blow could be avoided with a good pair of safety glasses.
In addition, more and more people who play paddle, whether indoors or outdoors, wear sports glasses, a circumstance which is also advised by the specialist in sports visual health Helena Rubio: “in this sport it is advisable to wear sports glasses which, at the same time as protecting against UV radiation from the sun, in the case of playing outdoor paddle, protect against the possible impact of the ball or the shovel itself”.
In general, all sports glasses must be comfortable, ergonomic, multipurpose, and with a high sun protection factor. Brands have realized the potential of this market and now it is possible to find hundreds of models for all tastes and styles, and that meet the qualities of a good technical lens.
Suitable materials for sports eyewear
The frames and lenses of sports eyewear are made of highly impact-resistant materials. These materials are often patented by frame manufacturers and there is a wide variety of quality, strength, lightness and, of course, price. The most common materials are acetate, plastic, TR-90, aluminium, titanium and even carbon fibre. You have to be very careful with the choice of frame, as each sport needs a model that meets different requirements, so it is advisable to be advised by a specialist.
The expert’s advice is even more important in the choice of lenses. “Each lens is indicated for a specific sport and a specific use, as the lenses are responsible for taking our sports performance to the highest level, the visual demands are very different in one sport and another, so each lens will enhance some details or tonalities more than others,” adds Helena Rubio, who adds forcefully: “how we see through our glasses is a detail that can make the difference between first or second.
The most common material with which the lenses of a sports goggle are made in polycarbonate, due to its high resistance to shocks. And it is essential that it can withstand the impacts of elements that can go at high speed, such as a ball thrown by an opponent.
