When eyes are exposed to too bright light may develop problems that may eventually lead to visual impairment or blindness. This calls for regulation of light that comes into contact with your eyes. This can be done so by using sunglasses. These are special materials that are worn on the eyes primarily to prevent exposure of the eye to harmful or discomforting light. This is achieved through the attachment of the appropriate lens which is a material that converges or diverges light in specific degrees. However, there are many sunglasses lens types and you should choose the best for your eyes.
They perform more or less the same functions but they have slight differences which are as a result of precision, specialization, and specification. Functions include the provision of comfort, clarity, and security. Prevention of glares and strong beams and glares is the main purpose wearing them.

Other functions may include hiding eyes. This may be as a result of weeping, red eyes and lack of either of the eye. They can also be used for styling and fashion as well as hiding identities by criminals.
These gadgets can be chosen from a number of categories of different colors, styles, and designs. Aspherical lenses are one of the best lenses to use.

They can also corrective lenses that rectify visual distortions. They are thinner and lighter as well.
Another type is the bi and trifocal. They are good in light reduction as well as fixing of near and long-sightedness cases respectively. They are mostly used by people who are experiencing age-related vision problems. Antireflective are used to reduce straining of the eye caused by bright glares and reflections. They also reduce abnormal vision characteristics observed during the night periods. They improve the clarity of seeing.
Polarized and blue-blockers cuts down reflections as well as reducing straining and effects of blue bright lights. These lights include welding, electrical shock flames, metallic flames and other related lights. They are also used to limit light from screens like those of computer monitors, tablets, smartphones and TVs among other devices. They also have appealing styles and can be used for beauty purposes.
Scratch resistant are coated with certain materials that extend their lifespan. It is impossible to make a lens scratch proof but the coating provides protection for a period of time from surfaces that come into contact with them. In short, it minimizes wear and tear.
