Sunglasses: Lenses
Over the years sunglasses have become more than just a fashion accessory. They multitask to protect your eyes from the harsh rays of the sun, improve performance in sports, driving and other outdoor activities, creating sharper images to enhance vision. Choosing a pair with the right combination of filters is critical to ensure you get the most out of your sunglasses.

Different tints or colours for lenses not only make an edgy fashion statement, but they also protect your eyes from harmful UV rays, diffuse light so you can see through glaring light, reduce eye fatigue and help improve performance in outdoor sports driving outdoor activities.
Gradients Tints
Gradient lenses are tinted from top to bottom – darkest at the top, with minimal colour towards the bottom. They look stylish, help protect your eyes from ultra violet rays and are useful for reading while looking through the lighter area when outdoors.
Mirror Tints
These lenses are made with a mirror-coating that reflect light from the lens and protect the eyes from glare as well as harmful UV rays. They are stylish with their bright reflective colours that they come in.
Photochromic
Photochromic lenses are clear indoors and darken automatically when exposed to UV rays. The change in colour happens gradually and is based on the intensity of UV exposure which means you can have a single pair to tackle eyesight issues indoors and also avoid glare outdoors.
Polarized
Polarized lenses have a filter to reduce the glare created by strong reflections of the sun. They can also increase the clarity and quality of vision. People who suffer from light-sensitivity find them especially useful.
UV Protection
Overexposure to UV rays is harmful for your skin and poses a threat to eyes and the delicate skin around them. Sunglasses with UV protection are sunblock for your eyes
