I never wear sunglasses. Why don't I have any problems?
The effects of UV radiation on the cornea are usually not immediately noticeable. You only start to experience the consequences later in life. To maintain good vision for as long as possible, it's therefore important to take good care of your eyes from an early age. For example, by wearing good sunglasses. With snow blindness (arc eye), your cornea becomes inflamed, and you'll notice the effects of UV radiation within a few hours.
Do I also have to wear sunglasses in the Netherlands?
In the Netherlands, UV radiation is lower than around the equator. On holiday in Southern Europe, for example, the radiation is higher than in our own country. However, UV radiation can also increase significantly in our country. Be sure to wear sunglasses in the summer between 12 noon and 3 p.m. UV radiation reflects off sand, water, and snow, and its intensity is higher at high altitudes. Therefore, extra caution is advised on the beach, on the water, and in the mountains (especially in the snow).
When is UV radiation at its highest?
UV radiation is highest during the summer months, between 12 noon and 3 p.m. UV radiation increases as the sun rises. Therefore, radiation varies by season and time of day. UV radiation is highest in the summer, between 12 noon and 3 p.m. Temperature has no effect. The amount of moisture, cloud cover, and dust in the air do have an effect, as does the amount of ozone. The ozone layer protects against UV radiation. You can view the predicted daily solar intensity on the KNMI website.
Why do children's eyes need extra protection against UV radiation?
Children are more vulnerable to intense light and UV radiation. Their pupils are larger and their lenses contain less protective pigment than those of adults. Without proper protection, excessive sunlight can even lead to permanent eye damage. Therefore, good sunglasses are especially important for children. The younger the child, the more vulnerable their eyes. Therefore, it's especially important to be careful with babies. Their faces should always remain in the shade, and it's recommended to protect their eyes with good sunglasses and a wide-brimmed hat.
Eye damage due to excessive UV radiation
Do you regularly suffer from dry, itchy, or even watery eyes? Excessive UV radiation is likely the culprit. To prevent permanent eye damage, it's important to be aware of your symptoms.
