Sunglasses of greater protection

• April 26, 2024

Buy lenses without proper sunscreen, just to be fashionable, can cause the progressive loss of sight. It sounds exaggerated, but the reality is that the damage is gradual and can trigger, in the medium and long term, in conditions ranging from conjunctivitis or cataracts, to the fearsome macular degeneration.

In this regard, the National Vocalía de Óptica Oftálmica y Acústica Española, undertook an intense campaign to raise awareness of the importance of protecting the eyes from solar radiation.

The sun is a source of ultraviolet (UV) radiation that passes through the atmosphere and reaches the eyes. Over time, if the correct protection measures are taken, different ocular pathologies appear, due to the cumulative exposure to UV rays.

The less severe are the edema (accumulation of fluid in the eye), erythema (inflammation of the eyelids) and conjunctivitis (inflammation of the conjunctiva).

Among the most dangerous are two: cataracts, which is the loss of transparency of the lens which can lead to the progressive lack of vision and macular degeneration, which is a degenerative disease that affects the center of the retina and involves loss of visual acuity, reaching in many cases to cause blindness and for which there are no corrective surgeries, as in the case of cataracts.

Pupils who take care of the eyes

Researchers from the Universidad Complutense de Madrid, headed by the doctor, Celia Sánchez Ramos, found a way to adapt a new filter to contact lenses that strengthens the natural protection of the eye and helps prevent damage caused by solar radiation.

The yellow filter protects against UV rays, also 13% of the non-solar lighting that surrounds a person every day and which, in a noxious and imperceptible way, can harm the health of the eyes. Although protective contact lenses are not yet marketed, the results have been very positive.
