What is Ultraviolet (UV) Light? Harms of UV Light and Ways to Protect Yourself
What is ultraviolet (UV) light?
The rays with wavelengths between 100-400 nanometers (nm) are called ultraviolet rays or ultraviolet rays. The main source of these rays is the sun. UV rays contribute to the total light emitted by the sun. Since our eyes cannot perceive these short rays, we cannot see UV rays with the human eye. Ultraviolet rays are a type of radiation and although we cannot see or feel the radiation, we can observe the harmful effects of these rays.
What are the types of ultraviolet (UV) rays?
UV rays are divided into three categories: UV-A, UV-B, and UV-C. All three types of UV rays are very harmful to the skin and eyes. The ozone layer prevents UV-C rays from spreading to the world. Sunglasses with UV400 protection help prevent UV-A & UV-B rays from damaging the eyes.
Where are ultraviolet (UV) rays found? Where are UV rays used?
Ultraviolet light technology is widely used in many different areas due to its antiseptic properties. UV light technology is used in many public areas such as hospitals, factories, public transportation, hotels, schools. UV lamps with high brightness quality are preferred in the lighting sector. In addition, UV light technology is used in different sectors such as eye-catching illuminated signs, skin disease treatment, water treatment and solarium services.
What are the harms of UV rays?
We can classify the damages of UV rays as damages on the skin and eyes. We are exposed to UV rays in every season and every hour of the day. How much you are exposed to UV rays and how well you are protected will vary depending on how much you are affected by these rays. UV rays can cause certain eye diseases and vision problems.
The rays reflected from surfaces all year round can cause short-term or long-term problems. Light sensitivity, blurred vision, pain and redness in the eyes are some of the symptoms that can occur when exposed to UV rays. UV rays can cause serious eye diseases in the future. The cornea layer in our eyes absorbs UV rays, but if exposed to UV radiation for a long time, the tissue is damaged and cannot fully perform this function.
UV rays can cause damage and loss of skin tissue when in direct contact with the skin. In addition, prolonged exposure to sunlight can cause burns. UV rays cause living tissues to age prematurely.
Ways to protect from UV rays
Although it is not possible to provide 100% protection against UV rays, the precautions you take will make a difference. First of all, since your exposure to the sun is directly related to your exposure to UV rays, it is important to be conscious during the midday hours when the sun's effect is felt the most.
Every age group, especially children, is sensitive to sunlight. It is important to use sunscreen for your skin and to reapply it at regular intervals. Using a hat or umbrella can also be preferred for better protection. It is recommended that you wear sunglasses with UV400 filters to protect your eye health.

- The colour of the lens does not determine UV400 protection. All sunglasses must have UV400 protection.
- Children's eye lenses transmit much more harmful UV rays than an adult's eye lenses.
