Polarised lenses are a result of the constant evolution of sunglasses and glasses. In the quest to protect people’s eyes, continuous improvements have been developed and the quality of lenses vastly improved. This has led to the development of polarized lenses. But what are they?
Polarised glasses are glasses that contain vertically polarized filters that counter reflected sunlight from reflective surfaces like water or car windows. In other words they reduce or remove glare so vision is not impaired. Polarized glasses have been used for decades by people who require clear vision to perform their sports and the technology behind them has been persistently developed.
Polarized lenses enhance contrast and colour perception, which helps improve vision. Colours appear bolder and brighter through this type of lens. Clarity of lenses is thus a benefit which can be attributed to the enhanced depth perception and visual accuracy these lenses provide.
Many people suffer from light sensitivities, making these lenses very beneficial to those who are afflicted. The lenses reduce the strain of computer screens and televisions on sensitive eyes. Another benefit is the reduction of eyestrain. Relieving the eyes of this stress helps prevent the development of more serious vision problems. The reduced glare and increased visual clarity allows the eye to relax.
There are different types of polarized lenses on the market. When simplified, there are essentially two types of lenses available. These are the 0.75mm lenses and the 1.1mm lenses. Anyone looking to purchase polarized lenses should understand the differences between them. The difference between the two can be found in the thickness of the film used to create the polarization.
For snow sports, an amber or vermillion tint is preferable. Water sports require a dark grey or black tint. For freshwater and shallow water fishing, red, orange or blue tints are favourable, depending on the lighting conditions. Brown or orange tinted glasses are best for cycling whilst a blue or green tint is great for tennis, soccer and other ball sports. Golf needs a tint to deal with high contrast, which is best found in brown or rose. Lastly, driving requires a gradated pair of lenses, meaning the tint is lighter in the middle and darker at the top and bottom. A brown or green tint is best in bright light and yellow in a dim light.
Polarized lenses can be used on a daily bases, assisting one’s eyes in remaining strong for as long as is possible. The use of these lenses is a very worthwhile investment which one will thank themselves for in the future.
