Which is the Best for Sun Protection?

Even though there are several types of lenses, polarized lenses are unraveled when it comes to protecting your eyes from sun damage. Besides offering protection against UV rays, they have other benefits.

Polarized lenses offer UV protection from harmful sun rays and go the extra step to reduce the glare of rays reflecting on surfaces like roads, water, or snow. They are the best option for someone who spends most of their time outdoors.

These lenses contain a different material than the standard sunglasses. A special coating is usually applied on the surface to filter light. The chemical used on the coating has molecules that align in a particular way to ensure some of the light filters through. They resemble the curtains in your house – they block some sunlight but not all of it.

The lenses only allow light that hits the lenses vertically to pass through. If the lenses are hit by light horizontally, it does not penetrate. Instead, it bounces off your lenses. For this reason, everything may appear darker when you are wearing polarized glasses. Interestingly, things around you should look clearer despite appearing darker since there are no added glares from the sun bouncing off objects and surfaces around you.

Which Color Lens is Best for the Bright Sun?

When choosing a lens for the bright sun, personal preference is a huge determining factor. Nonetheless, some lens colors are considered effective in bright sunlight. Gray lenses are the best option for the bright sun since they offer good protection against bright light without compromising contrast or clarity.

Other lens colors ideal for bright sun are brown and amber lenses. Besides blocking UV rays, they improve contrast and enhance depth perception. These colors are ideal for outdoor activities such as golfing, hiking, or fishing. You can also consider green lenses since they provide good contrast in bright conditions and reduce glare.

Benefits of Sun Lenses

Sun lenses, also known as sunglasses, offer several benefits to the eye and overall vision. Sun lenses protect the eyes and improve visual comfort, especially in bright sun. The following are the main benefits of sun lenses;

  • Protection from harmful UV rays: Sunglasses offer protection against harmful ultraviolet rays produced by the sun. If they reach the eyes, they cause several eye disorders and damage the skin surrounding the eyes. Interestingly, sun lenses provide 100% UV protection, thus safeguarding the eyes and the skin around the eyes from conditions caused by UV rays.
  • Reduced glare: For reduced glare, polarized lenses are the best. They reduce glare from reflective horizontal surfaces such as roads, snow, and water. By reducing glare, they improve visual clarity.
  • Improved color perception: In bright conditions, specific lens colors like brown and copper enhance contrast and color perception. Helps in outdoor activities
  • Protection from physical objects: Sunglasses protect the eyes from physical objects, such as debris which may enter the eye accidentally.

Side Effects of Sun Lenses

  • Eye strain: If your sun lenses are not properly fitted or do not offer the correct level of polarization, they cause eye strain and fatigue.
  • Visual discomfort: You may experience visual discomfort or light headaches, especially when you are new with the lenses.
