You need to invest in polarized glasses for their tremendous benefits in protecting your vision. These are better to let you enjoy the great Kenyan outdoors regardless of whether you’re hitting the beach at Mombasa or visiting Tsavo National park to check the famous lions. Polarized glasses are ideal to prevent eye damage in hot weather by lessening the risk from bright glare.
What is glare?
Unpolarized light includes that from the sun, light bulb, or flame. Such light sources emit light waves moving in all directions. Altering the direction of light waves especially when they hit a smooth surface leads to reflection where the light is partially polarized. This is known as glare and it’s angled horizontally towards the eyes. Prolonged exposure of the eyes to partially polarized light waves harm vision. Bright light and glare cause squinting, temporary blindness, and eye fatigue.
Need for polarized glasses
When you go out in the bright sun and find yourself shielding the eyes from a flash of glaring light puts your vision at risk. Lessening the effect of polarized light and glare effect is possible by forcing the light to go through a polarizing filter before it reaches your eyes. This filter can be in form of specially made polarized glasses with different lenses including progressive, bifocal, or photochromic lenses.
The best way to polarize light entering your eyes is to invest in quality polarized sunglasses that reduce glare and make it easier to see in bright weather. These glasses prevent light waves moving in multiple directions instead of up and down from reaching your eyes.

Choosing polarized glasses
There’re polarized filters with a high tech film in strategically placed molecules for blocking specific light waves that might cause glare. These filters are placed between two thicker and heavier lenses compared to non-polarized options. The lenses in polarized glasses can be colored at about 75 percent rated at a darkness scale ranging from A, B, and C. When ordering polarized glasses, keep in mind that C means the glasses have darker tinted lenses. For ultimate outdoor protection, choose glasses with lenses with a combination of UVA and UVB protection for blocking out 100 percent of harmful rays.
