While browsing the collection, to facilitate and help your choice, simply click on the "size guide" available on each model. In addition to personal taste, brand, model, color, etc, the parameters absolutely to consider are the following:


Basic for wearing glasses comfortably and aesthetically pleasing and suitable for the shape of our face. If you already own a pair of glasses, try to check if the values ​​are indicated on the frame. If they are present, they are three numbers. The first number represents the size of the lens, the second the size of the bridge (space where the glasses rest on the nose), the third number represents the length of the temples. If you feel comfortable with the current glasses, the values ​​indicated are worth considering.

If not, use these simple precautions to find the most suitable eyewear for you. Pay attention to the length of the temples, a wrong choice can affect the comfort of the glasses on your face.



Lens treatments that reduce glare are tints, mirror surfaces, anti-reflective treatments, polarizing films and photo-polar combinations. The table describes the benefits of each of the treatments.

Grey lenses deliver true color and are advisable for extended periods of use in extreme conditions. Yellow lenses enhance brightness and absorb blue light. These lenses are effective for some users (driving during the day for seniors, skiing in fog). However, yellow is not advisable when the light is intense or for those with less than optimal vision. Yellow lenses are not a good solution for night driving in very dark conditions. Yellow lenses absorb too much of the ambient light.

Brown lenses improve contrast and image resolution. Ideal in changing light conditions, brown tints also absorb harmful blue light. Amber lenses brighten cloudy, hazy, or foggy skies are excellent for contrast and help to minimize eyestrain. Lastly, they are good for hunters, pilots and snow skiers. Rose lenses enhance contrast and are perceived as relaxing and are best in green or blue environments (water, grass) and can reduce blue light. Last, green lenses provide better contrast and a more precise and relaxed vision.

Polarized Lenses provide comfort for patient’s eyes by reducing glare, most importantly eliminating blinding glare (intense flat surface reflections) enhancing contrast and clarity as well as being 100% UV protective. The result is reduced eye stress and strain.


The index classifies the darkness of the lenses and recommends use based on environmental conditions. As we can see, the protection index has 5 categories that increase with the intensification of light. It starts from Category 0, when the absorption of light is very low and is used for safety lenses and as a cosmetic or fashion. Category 1, which allows for 80% to 43% transmission, is for indoor and cloudy days. Category 2 reduces light transmission to 18% for standard lighting. When there is a lot of sun, as in the case of the sea or the mountains, Category 3 is suggested, which allows only 8% of the light to pass through. The last one is Category 4, which allows from 8% to 0% of light and is used in case of intense lighting, for example trekking at high altitude. It should be noted that category 4 is not suitable for driving.


Premature aging is another result of too much UV since UVA rays are the rays of aging. It is estimated that 90% of premature aging around the eyes is caused by UV damage. So a nice pair of sunglasses costs less than cosmetic surgery around the eyes. And now that you have discovered everything about sunglasses, do not miss the opportunity to find the most suitable model for you and see the collection immediately.
