The sun provides us with energy and well-being, but unprotected exposure to ultraviolet rays can have serious effects on the eyes. Often, we only think about UV protection for our skin, forgetting that our eyes are just as vulnerable. One of the conditions associated with prolonged UV exposure is cataract, a common cause of vision loss with age. How do we protect our eyes and what is the connection between UV radiation and cataracts? We find out below.
What are UV rays and how do they affect the eyes?
Ultraviolet (UV) radiation is invisible to the human eye and is divided into:
-
UVA – penetrates deep into the structures of the eye
-
UVB – can affect the cornea and lens
Repeated and unprotected UV exposure contributes to premature aging of the eye and gradual deterioration of the lens.
What is a cataract?
Cataract is the clouding of the lens, the natural lens of the eye, which leads to:
-
blurred vision
-
duller colors
-
difficulty seeing at night
-
increased light sensitivity
Although cataracts often appear with age, exposure to UV rays is an important and preventable risk factor.
The link between UV protection and cataract prevention
Studies show that UV radiation accelerates structural changes in the lens, favoring the appearance of cataracts. Constant UV protection can slow down this process and reduce the risk of long-term ocular damage.
The good news is that prevention is simple and accessible.
How can you protect your eyes from UV rays?
-
Wear glasses with 100% UV protection
Sunglasses or prescription glasses must provide complete UVA and UVB protection. The color of the lens does not guarantee protection – only a certified UV filter does.
-
Choose lenses with built-in UV protection
Modern prescription lenses can have an integrated UV filter, protecting the eyes even on cloudy days.
-
Don't forget the children
Children's eyes are more sensitive to UV, as their lens is more transparent. Eye protection should start from an early age.
-
Protect your eyes all year round
UV radiation is present not only in summer, but also in winter, especially in snowy areas, which reflect light.
The role of regular optometric check-ups
A regular check-up can detect early:
-
changes in lens transparency
-
early signs of cataracts
-
the need to adjust protective lenses
