A Look Into 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.

Sunlight has its own set of benefits. However, it also has its own fair share of negative side effects one of them being causing impaired vision. The two types of rays that are known to cause these effects are UV and blue rays and researches carried out in various parts of the globe show them as the major reasons behind many eye diseases. This calls for one to take the best action in ensuring that they protect their eyes from such elements.

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 lenses have to be highly polarized. When the eyes are exposed to the rays of the sun for extended periods of time, vision tends to become distorted. This, in turn, causes both the brain and eyes to strain too much since visual clarity is interfered with. However, lenses that have maximum polarization will tend to filter the different types of color bands so that only a natural spectrum of color is allowed to pass through the lenses.

There are various types of materials used in the manufacture of glass lenses, but none can beat the awesome qualities of Serilium. This material is a form of polycarbonate that is known for its great features providing optical accuracy. They are also lightweight and strong that is they do not break easily.

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.

When purchasing sunglasses, there are certain things that people tend to overlook. One such thing is whether the glasses offer a good fit or not. It is until they have made the purchase, which they realize that they are not a fit for them. Therefore, in order to avoid such scenarios, try out different ones so that you find the perfect fit for yourself. You should also go for a shape that is both appealing, but also allows for maximum blockage of UV 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.
