Choosing the ideal pair of sunglasses might be stressful because so many variations are available. Sunglasses are more than just a piece of fashion jewelry; they protect your eyes from UV rays that could damage them and ease eye strain. Polarized lenses filter reflected light and eliminate glare from surfaces such as water or snow. Polarized glasses can help reduce squinting and eye strain if you spend time in the sun.
Sunlight reflects off smooth, shiny surfaces, such as water or snow, and can create a bright, distracting glare that makes it difficult to see. Polarized sunglasses filter out horizontal light rays that reflect off these surfaces and only allow vertical beams to enter the eye, eliminating the glare and improving visibility. Polarized sunglasses are great for sports like fishing, golfing, skiing and other outdoor activities. They are also helpful for driving during the day when sunlight reflects off the windshield and can be distracting.
To test whether your sunglasses are polarized, hold them to a reflective surface and tilt one lens about 60 degrees. If the glare is significantly reduced, your lenses are polarized. However, it is important to note that polarized sunglasses may make LCD screens appear dark or black, so they aren’t ideal for use with digital devices or while looking at LED screens.
Blocks Harmful UV Rays
Polarized sunglasses for women aren’t just a fashion statement and can help keep your eyes healthy. When sunglasses are labeled as UV-blocking or polarized, the lenses will reduce glare and, if listed, protect against harmful ultraviolet (UV) rays. UV rays are reflected sunlight that can cause eye damage, such as cataracts and degrade the retinas. Polarized sunglasses work by filtering out horizontal beams of light that create glare. It allows only vertically oriented light to pass through, helping to minimize glare and improve visual clarity.
Be sure to select a pair of polarized sunglasses that offer 100% UV protection to help prevent the risk of UV-related eye damage. You can also test your polarized sunglasses on a reflective surface to see how they reduce glare. They will also likely have a darkening effect on LCD screens like those on cell phones and certain computers. It may be inconvenient for those who use these devices, but it is a small price to pay for improved vision and protection of the eyes from UV-related damage.
Reduces Eye Strain
Polarized sunglasses reduce glare from the sun, water, snow, or other reflective surfaces. When severe, this glare can strain the eyes and give you headaches. Polarization helps prevent this by filtering out light that reflects horizontally off flat surfaces like metal, glass or calm waters. It means only vertically polarized light passes through the lenses, while horizontally reflected light (like glare) is blocked.
If you are unsure whether your sunglasses are polarized, try this simple trick: Hold the sunglasses up to a pair of non-polarized sunglasses at right angles to each other. If the lenses turn dark or nearly black, they are polarized. However, polarized lenses make liquid crystal displays (LCDs) on digital devices like phones, bank machines, tablets and computers appear dimmer than usual. It isn’t a big deal, but you might have to occasionally pop your sunglasses up to use these devices.
In addition to protecting your eyes from glare that causes eye strain and can be dangerous, polarized lenses are designed to improve contrast. It allows you to see more detail in bright environments such as snow and water, making them better for skiing, fishing and boating activities. The polarizing lens coating blocks out horizontal light, creating glare. It means that when you are on a beach looking at the ocean waves, they look more like a rock in the water than a blinding wave. The same goes for sunlight reflecting off a road, lake or snow.
Sunglasses are an essential part of any wardrobe, especially during warm weather. However, not all sunglasses are created equal.
