The Technology Behind 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.

Good sunglasses should possess some quality features. For one the infusion molding process should be used during manufacture. One of the most common things that cause bad vision are layers meaning that a higher number of layers will cause distortion and limit vision. This is normally witnessed in glasses where the layers have been glued to the lens. However, in infusion molding process, the glasses created are clear and provide optimum quality.

Sunglasses should possess certain features in order for them to reach top of the line quality threshold. One involves the manufacturing process where the infusion molding process should be used. Most glasses are made by gluing the layers onto the lenses. This, in turn, causes optical distortion, since there are basically too many layers. However, in glasses where the infusion molding process has been used, more clarity is provided; thus, ensuring accuracy.

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.

The lenses used should also be made from quality material such as Serilium. This is normally top of the line quality since it provides maximum clarity. It is also made in such a way that it offers comfort due to its light nature in addition to being strong.

Another important feature is that they should provide protection against harmful sun rays such as UV and blue rays. The details used in the manufacture process should offer a hundred percent sun blockage. Additionally, they should also be able to reduce the level of glare onto the eyes. Apart from all these, they should also have quality tint so that maximum blockage of these harmful rays is made possible.

The glasses should also fit. Fitting glasses are good because they look better and they are also effective at blocking out harmful sun rays. They should be comfortable not being too tight or too loose. The frames should also fit just right so as not to allow UV rays to pass in through the sides. In addition, the shape should be capable of looking good so as to enhance the facial features. The shape should be just right to enable maximum blockage of the harmful rays.

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.
