How can polarised glasses help your vision?

Polarized glasses are becoming quite popular and many people prefer them as these have stylish appearance and can reduce glare. However, polarized glasses come with many benefits other than just providing aesthetics, especially for those who usually spend a lot of time being outdoors.

Polarized glasses are sunglasses with a special filter embedded on the lenses to reduce glare. This filter constitutes a series of tiny vertical lines that only permit light waves to pass through it in a particular direction. When light waves bounce off flat surfaces, such as water or pavement, they become horizontally polarized, creating intense glare that can be harmful to the eyes. Polarized glasses block this horizontal light, reducing the glare and improving visibility.

How do Polarized Glasses Work?

Polarized glasses block the horizontal light waves that cause glare, while allowing the vertical light waves that are required to have a clear vision. Polarized glasses block the polarized light waves through a special filter made of vertically oriented microscopic crystals or a thin film placed on the lenses. This filtering effect can be achieved by placing a polarizing filter on the optical lenses of the glasses. The filter is composed of vertical lines that permit the vertical light waves only to pass through it blocking the horizontal waves of light.

The glasses lower the reflected light reaching the eyes, making it easier to view clearly and reducing eye strain and fatigue. Linear polarized glasses works great for outdoor activities such as driving, fishing, and skiing, where glare coming from reflective surfaces can be a real safety hazard. However, they may not be suitable for certain activities such as flying or skiing on overcast days, as they can reduce visibility in low-light conditions.

Benefits of Polarized Glasses

Reduced Glare - Polarized glasses can help you reduce glare effect, making it suitable for outdoor activities including boating, fishing, skiing, and driving. This decline in glare helps to improve visibility, making the visibility of objects easier in bright sunlight.

Improved Contrast - Circular Polarized glasses enhance contrast, making it easier for you to view objects even in low light conditions. This is helpful for people especially with certain eye conditions that disrupt their ability to view in dim light.

Protection from Harmful UV Rays - Polarized glasses protects your eyes from harmful UV rays, which can damage your eyes and skin. This protection is important for people who are usually outdoors.

Less Eye Strain - Polarized glasses can lessen the eye strain by lowering the glare and improving visibility. This is helpful for people spending long hours on working in outdoor surroundings or driving.
