Get the best lenses, knowing the benefits and disadvantages

There is a price for living in a country that has an average of 290 days of sunshine a year. If you live in Spain, Australia, south of the United States, South America, Dubai, Qatar…, you don’t often have to deal with snow shovels and parkas, but you almost always think about how the sun will affect you. From staying hydrated to using sunscreen, there are steps that everyone who lives in sunny areas should take to be healthy and comfortable in the sun, and wearing the right sunglasses with polarized lenses is one of them.

Choosing good sunglasses to protect you from the sun is especially important. Lenses with UV400 protection help protect the eyes and around the skin of the eyes from ultraviolet light, they do not remove distracting and blinding glare that causes visual discomfort in any sun situation.

Polarized lenses block out glare and reflections from the sun, but may not be the perfect solution for every situation. This article explores how polarized lenses work – their benefits, possible drawbacks, and where to buy them.

What is glare or reflexes?

When a beam of light hits a flat surface, it is polarized or reflected horizontally. The beam is concentrated and blinds anyone who observes it. This is known as blinding glare.

These reflections can be uniform, i.e. the light reflected from a soft service. Uniform reflections would be light reflected from the road, or from the bumper or rear window of a car. They can also be non-uniform, which is light reflected from an uneven surface. An example of this would be light reflected from running water or a piece of ice on the road.

In any case, the desirable result is to filter out disturbing reflected light and provide a clear visual experience for the user.

What are polarized lenses?

During the development of the manufacturing process, a specific chemical is applied to an eyeglass lens to polarize it. The chemical is shaped into a vertical pattern, which reorders the light. This pattern blocks the light that is horizontal to eliminate glare, which is similar to how a window shade works. Glare usually occurs when light waves are bounced off reflective surfaces, such as a mirror, a snowy slope, or a shiny car bumper. Because the surface is horizontal, the light is reflected horizontally. When polarized sunglasses are worn, the surface blocks the glare by filtering out horizontal light waves that do not fit the chemical laminate pattern.

Images may appear darker when using polarized lenses. However, when the reflection is removed, image details are easier to see and can reduce eye strain. In addition, polarized lenses also provide protection against harmful UV rays.

Polarized Lens Differences

Low-cost polarized sunglasses differ from more expensive lenses considerably. Low cost sunglasses maybe only have a thin chemical laminate on one side of the lens. The thin coating can only provide a minimal benefit and the small layer can be easily scratched or scraped off. You may also notice variations in your lenses, as they are usually mass-produced and sealed lenses that are of lower quality.

Polarized sunglasses are available in many stores, from pharmacies to high-end sunglass shops. If you buy these protective sunglasses to reduce eye strain, you should make sure that your money is worth it.
