Sunglasses are not just a style accessory – they are essential for protecting your eyes from ultraviolet (UV) radiation. Many people believe that the darker the lens, the more protection it offers. In reality, UV protection has nothing to do with the color of the lens.
What matters is the quality of the lens and the UV filter it has.
By following a few basic principles, you can choose sunglasses that truly protect your eyes.
Ultraviolet radiation comes from the sun and is not visible to the naked eye. It is divided into UVA and UVB, and long-term exposure can cause eye problems.
It is important to know that:
• UV radiation is present all year round, not just in the summer
• Can affect the eyes even on cloudy days
• Reflects on surfaces such as water, sand and snow
Proper protection is essential in every season.
Dark glasses are not enough to protect the eyes. A proper lens must meet specific specifications.
Important features:
• 100% UV radiation absorption (UV400)
• Uniform shading without distortions
• Quality construction that does not alter vision
• Certification of conformity (CE)
These elements ensure real protection and comfort.
One of the most common mistakes is associating color with UV protection.
In reality:
• A dark lens without a UV filter can be dangerous
• A light-colored lens with UV400 can be perfectly safe
• Color only affects the perception of contrast and brightness
For example:
• Brown lenses increase contrast
• Gray lenses preserve natural colors
• Yellow/orange improves visibility in low light
But none of this is related to UV protection.
Daily sun exposure without proper protection can affect eye health in the long term.
UV protection:
• Protects against damage to the cornea and lens of the eye
• Reduces the risk of cataracts
• Protects the retina
• Contributes to overall eye health
Prevention is always more important than treatment.
