Interesting Facts About Eyeglass Lens Quality

The wide range of eyeglass lenses today makes it difficult to decide which quality best suits one’s needs. This article tells you more about the quality of spectacle lenses such as aviation sunglasses for example and gives you a brief overview. As a rule, only a competent specialist can advise you optimally on the quality of your spectacle lenses according to your requirements and needs. 

How Is A Spectacle Lens Made?

Spectacle lenses today typically consist of four layers:

the base lens is the central element and is produced in the desired shape (depending on the correction, i.e., the optical effect)

the hardening layer is a sealing to protect the glass from scratches

the anti-reflective coating ensures the transparency of the glass and minimizes annoying reflections

the protective layer serves to repel dust and liquids

What Types Of Spectacle Lenses Are There

Those who already wear glasses like american made sunglasses for example have certainly heard of one or the other designation of spectacle lenses. For anyone venturing into unfamiliar territory, here’s a quick summary.

Single-vision lenses work like binoculars or reading glasses because they only correct faulty vision

Multifocal lenses combine several optical corrections and are mainly used for progressive glasses

Special filter glasses or edge filter glasses provide the necessary protection or visual support

Different Factors Play A Role

To know the adequate quality of your spectacle lenses and to choose the best solution, different elements must be taken into accounts, such as the correction, the wearing conditions, the type of frame, and the budget. Other individual conditions and wishes on your part can also be taken into account during the consultation.

Spectacle Lens Quality – Plastic Or Mineral Glass

The choice of a plastic or mineral glass ultimately depends on the elements already mentioned, which will be considered during the consultation.

Where a very high scratch resistance characterizes mineral glass, plastic glass is distinguished by its break resistance. Mineral lenses can be very thin, guaranteeing a beautiful aesthetic in cases of severe visual impairment. Plastic glasses, however, are popular due to their lightness and pleasant wearing comfort.

As you can see, the quality of spectacle lenses cannot be generalized or reduced to a single statement. Your needs, wishes, and the respective terms and conditions regarding the correction or choice of the frame are important.
