Light vibrates because it moves in waves. Light typically vibrates in a number of directions. However, light only vibrates in one direction when it bounces off a horizontal surface, such as snow, water, or the roof of a car. We refer to this process as polarisation.
The light is focused and strikes the eye directly since it only vibrates in one direction. Glare is what we term this focused light.
Non-Polarized Lenses
Sunglasses without polarisation are made to lessen the brightness of all lights. If your lenses claim to provide UV protection, they probably contain unique dyes and pigments that obstruct ultraviolet radiation from entering your eyes.
However, regardless of the direction the light vibrates in, this technology operates in the same way for all sorts of sunlight. Because of this, glare will continue to have a greater influence on your vision than other types of light.
Polarized Lenses
A chemical is applied to polarised lenses to block light. However, because the filter is applied vertically, only light that is travelling vertically can pass through.
Consider a picket fence with an inch between each slat as an example. If you hold a popsicle stick vertically, it would be simple to slip it between the slats. However, the popsicle stick won't fit between the fence slats if you turn it horizontally.
Benefits of using polarized lenses
GLARE REDUCTION
The best case scenario is that glare is annoying. It might even be harmful in the worst scenario.
According to studies, intersection collisions, which are a leading cause of traffic accidents, happen more frequently when the sun is at its glare-producing peak.
You can increase your awareness of your surroundings and potentially prevent accidents and injuries by decreasing glare.
BETTER CLARITY
Glare can impair your ability to see clearly even when it poses no danger. Polarized sunglasses are frequently used by outdoor enthusiasts and athletes in order to see more precisely.In comparison to non-polarized sunglasses, polarised sunglasses may also provide you with a more realistic representation of colour.
PREVENTION OF FATIGUE
According to research, solar glare might make you tired. Glare makes your eyes work harder as they attempt to make sense of the data they are taking in. Eye strain is another name for this type of overwork, which can make your eyes feel worn out, painful, or impossible to stay open.
WHICH Circumsatnces Suit Polarized Lenses?
In some circumstances, polarised lenses might not be the best option. For instance, polarised light is produced by devices with LCD displays. Avoid wearing polarised sunglasses while driving if the fundamental controls on your automobile are LCD displays.
But polarised lenses are a great option if you want to:
- Golfers
- Skiers
- Fishermen
- Motorcyclists
- Beachgoers
POLARIZED LENSES: ARE they better for my eyes?
Your eyes won't be protected from UV rays any more by polarised lenses than by normal 100% UV lenses. Nevertheless, they can improve your vision and reduce some eye strain. Consider purchasing polarised sunglasses if you frequently squint, even when wearing sunglasses. They might be a more cosy choice in your opinion.
Keep in mind to shield your eyes from UV rays at all times. Wear sunglasses whenever you go outside in the sun, and be sure they provide 100% UV protection.
