An Overview Of Sunglasses Lens Types

By Elizabeth Sanders


Protecting the eyes from elements that would cause harm and impair vision is important. This is why it is important to know the kind of sunglasses lens types that have been used in the making process. Additionally, the materials used in the manufacture have to be environment friendly such that they are light as well as durable. The design should also be appealing so as to add a stylish look to anyone wearing them.

There are various advantages of sunlight; however, there might be some cases where it has been known and proven to cause more harm than good especially to the eyes. In a number of studies carried out, it has been shown that the UV and blue rays cause damage; thus, causing optical inaccuracy. Therefore, as a safety measure people are advised to wear protective gear most especially around summers.

There are certain features that make for quality glasses. For instance, the best process to use in piecing together layers is the infusion molding. The more the layers between the eyes and what is being viewed, the more distortion there is. Instead of gluing layers to the lenses, manufacturers should embrace infusion molding. The advantage of using this process is that quality glasses that offer more clarity as well as optical accuracy are created.

The glasses should also be highly polarized. As the eyes get exposed to sunlight for a long period, they tend to become distorted such that one cannot be able to make out clear images. As a result, this forces too much brain activity and strain by the eyes to try and attain vision quality, which in turn leads to fatigue. To make sure that this does not happen, highly polarized glasses filter out color bands so that only a spectrum that is purely natural is allowed to go through.

In addition, the lenses should be top notch. Some of the material used in the manufacture process is a form of Polycarbonate or Serilium, which is known for its amazing qualities of offering optical clarity in addition to being light and impact-resistant.

In addition, they should as well offer maximum UV protection. They have got to block one hundred percent of the rays passing through to the eyes. They should be anti-reflective meaning that they reduce the amount of glare. The tint used should also be able to keep off as much light as possible; thus, offering maximum protection.

Good glasses are ones that are good fit. Imagine wearing glasses that are either too tight or too loose. Tight fitting ones will cause a lot of discomfort while loose ones will not offer maximum protection. Therefore, to be on the safe side it is best to choose one that is a good fit. Additionally, its shape should also be the best so as to help enhance your looks and also block as much sunlight as possible.

In conclusion, sunglasses serve a great purpose and that is protecting eyes from the harmful rays that might end up damaging vision. It is, therefore, paramount that you get to know what kind of features to look out for in order to make the right choice.
