New glasses? Here are the 5 features you need to pay attention to

by admin

From sun, from sight, from work. With very light or very eye-catching frames. From lenses with traditional or bizarre shapes. Glasses have become a full-fledged fashion accessory. But be careful not to underestimate its importance in terms of eye protection and health. Also because, thanks to the pandemic, in recent months we have been in front of a screen much more than we were used to while in the coming months, with summer just around the corner, we will spend a lot of time outdoors, under the rays of the sun. this is really the time to think about choosing the most suitable but also the safest glasses. Starting with the lenses. So here are five factors to look out for before making decisions.

Blue light protection

Lately, there is a lot of talk about blue light: the fault of the intensive use of digital devices and the greater exposure to artificial LED light and the consequent visual fatigue, headache, burning eyes. Set of symptoms called Digital Visual Stress. But the technology offers a solution: it is possible both to integrate specific anti-reflective properties for blue light, to reduce the harmful component, while maintaining the good one, and to have lenses that hide this protection inside the material of the lens itself, called “in material” , with the additional advantage, in addition to that of protection, to greatly limit the reflections visible on the lens, which often disturb the vision and are very visible for those who look at us from a monitor. Choosing a lens with this protection is important for those who are very “connected”.

UV protection

When choosing lenses it is essential to pay attention to the ability to screen UV rays, which must be maximum. Not only for dark lenses, but also and above all for light ones. The sun’s rays, in fact, reach us even in winter or when it is cloudy. What to check then? That transparent lenses still have protection from UV rays and that this protection is as wide as possible: in particular it is important that wavelengths up to 400nm are rejected, which the International Commission on Non-Ionizing Radiation Protection defined the standard of protection. Attention: in Italy 70% of ophthalmic lenses guarantee protection only up to 355nm while those in polycarbonate only reach 380nm.

The ability to eliminate viruses and bacteria

Occupying the center of the face, the glasses are in effect high-contact surfaces: they are touched hundreds of times every day with the hands, they protect the eyes from environmental pollution, atmospheric pollution such as that caused by the dropplets of those who speak around us . To minimize the risk of transferring viruses and microbes from the lens surface to the eyes, it is best to choose lenses that integrate antimicrobial capabilities. In particular, lenses that integrate silver nanoparticles have been shown to block 99.9% of viruses and bacteria.

Visual comfort

Before buying a new pair of glasses, it is good to go to an ophthalmologist. If vision is one of the fundamental checks for children in the first years of life and then at the beginning of school, after 40 it should be a good habit of prevention. To do every year. Glasses must respond precisely and in the best possible way to visual needs that change over time: if this does not happen, goodbye to comfort, even if the glasses are new.

Aesthetics

Glasses are health tools, but also beauty accessories. It is important to choose a shape and a frame that fits the shape of the face. Depending on its use, the lightness of the frame must be taken into consideration: those who wear them all day should prefer the light ones. Attention then to the temples, which must adhere to the head and wrap the ears well. Finally, in the age of selfies and online meetings, aesthetics also pass through glasses that do not reflect light and that allow the eyes to look their best.
