• The tone should be as dark as possible, allowing it to counteract the intense ranges of luminosity to which it is exposed.
• 100% UV protection.

Polarized sunglasses for kids

The harmful effects of radiation produced by ultraviolet rays accumulate over the years. For this reason, the use of polarized sunglasses is essential to avoid future deterioration. In the case of children, the vulnerability is even greater.

Because the lens is almost transparent until 10-12 years of age, are more susceptible to retinal damage . It is therefore essential to use polarized glasses for adequate protection of the little ones.

Prolonged exposure to solar radiation increases the risk of developing cataracts. In children, UV or A ultraviolet radiation can cause serious injuries.

Polarized sunglasses for the postoperative period

Laser-assisted in situ keratomileusis, also known as LASIK surgery, is a surgical procedure on the cornea. Its purpose is to improve the patient's vision and avoid the need for contact lenses or corrective glasses. It involves permanently modifying the cornea.

LASIK surgery is indicated to correct vision difficulties in cases of hyperopia, myopia and astigmatism. The use of polarized sunglasses is essential after surgery of this type for three basic reasons:

• Prevents damage to eye tissues by blocking ultraviolet rays.
• It reduces sensitivity to light by reducing the amount that can reach the eyes.
• The tendency to rub or scratch the eyes postoperatively can be avoided by wearing glasses.
