What are Polarised Sunglasses and Should You Buy Them?

Polarisation in sunglasses refers to a special type of lens coating that blocks glare caused by light reflecting off of surfaces such as water, snow, and pavement. The coating works by only allowing light to enter the lens in certain vertical orientations, effectively blocking horizontally-polarised light that causes glare.

Polarised lenses were first developed in the 1930s for use by pilots and boaters, as glare from the sun reflecting off the water or cockpit surfaces could be dangerous. They quickly gained popularity among outdoor enthusiasts, including anglers and water sports enthusiasts, as they greatly reduced glare and improved visibility.

Today, polarised sunglasses are popular among a wide range of people, including those who spend a lot of time outdoors, such as hikers, bikers, and skiers, as well as those who drive frequently or spend a lot of time on the water. They can also be beneficial for people who are sensitive to glare or have certain medical conditions such as migraines that are triggered by glare.

Polarised sunglasses can be especially beneficial for water sports and activities such as fishing, boating, and waterskiing, as they can greatly reduce glare and improve visibility on the water. They can also be beneficial for sports that take place on surfaces that reflect a lot of light, such as snow and ice, as well as for driving, as they can reduce glare from the road and oncoming headlights.

It's worth noting that polarised sunglasses aren't the best choice for all situations, for example, if you're doing activities that require you to see ice or snow surface clearly, like skiing, or if you're driving in certain areas, like in the mountains where you need to see the surface of the road clearly, polarised sunglasses may cause glare, making it difficult to see.

In summary, Polarisation in sunglasses refers to a special type of lens coating that blocks glare caused by light reflecting off surfaces such as water, snow, and pavement. Polarised lenses were first developed in the 1930s, they are popular among outdoor enthusiasts, and can be especially beneficial for water sports and activities such as fishing, boating, and waterskiing, as well as for sports that take place on surfaces that reflect a lot.
