The worst mistake would be to consider them an accessory. Sunglasses, even for those who have no vision problems, are a tool for prevention and well-being, even before beauty. We must choose them taking into account our eyes, any visual defects and the type of life we lead. With the aim of having maximum protection from UV rays, shielding only the light is not necessary. As explained by Paolo Vinciguerra, head of the Ophthalmology unit at Humanitas in Milan.
1. Protecting the eyes from radiation is a useful form of retinal disease prevention. The first thing to know is that depending on the time we spend indoors or outdoors, we will need a different protection.
2. The lenses must protect from UV rays, if they limit themselves to reducing the light in a non-selective way, they favor pupil dilation by increasing the passage of rays with a more harmful than beneficial effect.
3. To understand which sunglasses are the most suitable for our eyes, it would always be good to consult an ophthalmologist. Even if you have no visual defects. And if we really don’t want to go there, we ask the ophthalmologist for advice by choosing a shop that uses one. The photo-protection, in fact, must be calibrated on personal needs and lifestyle.
4. Who has a visual defect has a different tolerance to light depending on the problem, sunglasses will have to take this into account. Those who are farsighted, for example, are more sensitive, even indoors. Those with uncorrected myopia are more tolerant.
5. Do not save on the quality of the lenses which guarantees protection against UV rays, and correct vision.
6. The frame is a prosthesis, therefore it must adapt to the body rather than to the aesthetic taste. Like shoes, frames also have sizes: once we have chosen the model, we ask if there is the right size for us.
7. For those who are outdoors there are photochromic lenses that change the intensity of the color and the absorption of light in relation to the amount of UV rays to which they are exposed.
8. Those who have a slight defect or can see well can opt for curved lenses that also protect from side light.
9. The temples of the glasses must wrap, in the terminal part, the auricle or the curvature of the skull. If they are too long they make the glasses unstable and uncomfortable, if they are too short the lens will take a non-optimal inclination.
10. Glasses should be cleaned often with water and hand soap, drying them with soft tissues so as not to scratch the lenses. If you use the soft cloth you must then remember to wash it with delicate soaps or to change it frequently.
