Costa polarized lenses vs standard polarized lenses:

The polarization of sunglasses is quite familiar nowadays. Such lenses have some basic features of protecting eyes from glare and harmful lights alongside increasing visual clarity. So, are all Costa lenses polarized? Yes, But Costa polarized lenses are beyond the definition of polarization. Let’s analyze them with standard polarized lenses:

Polarizing efficiency:

Compared to the standard polarized lenses, polarized Costas are guaranteed to be 100% more efficient. Therefore, such Costa lenses are more reliable to reduce eye strain and enhance visual power.

Etching authenticity:

Costa polarized sunglasses especially the prescription Costas are easily marked for their distinctive etchings. These etched lenses create a more comfortable and stylish look than we expect from the standard polarized lenses.

Special edition of lenses:

Costa polarized lenses belong to a special edition called 580 lenses. This lens edition comes with two different materials, glass, and plastic. All lenses of 580 versions are made by highly skilled craftsmen to deal with unique color management.

On the other hand, standard polarized lenses have common materials and they are manufactured to serve the basic benefits of a polarized sunglass.

Absorbing level of HEV:

Costa and standard polarized lenses have a common feature of blocking UV rays but there is a difference in the ability to absorb harmful high-energy blue light. Costa lenses are more powerful than standard lenses in absorbing this light. This blue light can cause different eye diseases like macular degeneration, pterygium, cataracts, etc.

Color filtering or enhancing: Unlike standard polarized lenses, Costa polarized blocks and filters the harsh yellow light and naturally enhances the balance of blue, red, and green color and contrast. Moreover, Costas has multiple lens color options to adjust to different times, places, and outdoor environments. Especially mirrored lenses are produced to adjust to changing light conditions.
