Behind the choice of a good pair of sunglasses, there are many things to evaluate in addition to the aesthetic aspect. Here is a short guide that summarizes the main features.
Wearing sunglasses is always important, even more so in this period when you spend much more time outdoors and the sun's rays are more direct. Exposing yourself without any type of protection to sunlight means encountering problems and damage to sight: the most widespread problem is cataracts, as well as the opacification of the lens, a problem also linked to the lack of care that one has of one's eyes.
The advice is to use good and effective sunglasses to combat the onset of vision problems, but also for daily protection from UV rays that could create inflammation such as conjunctivitis or keratitis. There is no category more at risk than another, but certainly, there are weaker age groups: that of children ranging from 6 to 10 years (eye development) and adults over 55 (weakening of the eye).
Sunglasses not only protect us from UV rays, but they also represent an excellent defense shield against the wind that can carry pollen, insects, and dust, causing irritation, injuries, and infections. The sun's rays can represent a threat to our eyes, if not adequately protected, not only with annoying conjunctivitis and keratitis but in the long term also with significant damage to the cataract.
Thinking that eyewear is good for both the sea and the mountains means not taking into account the difference in the incidence of sunlight and that children up to 12 years of age are particularly sensitive and therefore more at risk from the possible harmful effects of the UV rays.
How to choose them

Behind the choice of a good pair of sunglasses, there are many things to evaluate in addition to the aesthetic aspect!
The selection criteria to be followed
Protect the eyes: Excessive exposure to UV rays can cause various eye problems, such as cataracts, inflammation, and tumors. If you want sunglasses that protect you from these risks, look for a pair that blocks at least 99% of UVB rays and at least 95% of UVA rays. Do not buy low-quality sunglasses, the label of which does not give any information about the degree of UV protection.
The style: Sunglasses come in any shape and size! Here are some quite popular varieties:
The color of the lenses: The color of the lenses not only responds to aesthetic factors but also affects the contrast and the ability to differentiate colors. Lenses of a certain type increase the contrast - which can be useful in some cases - but always at the expense of the ability to distinguish colors. This can cause problems in certain situations, such as when driving and having to distinguish the colors of a traffic light. Some glasses have interchangeable lenses and offer the ability to change the color of the lens depending on what you are doing.
There are still a number of other criteria to consider but those described above are the most important.
