TAVAT introduces the leading lens technology, only now being recognized as significantly important for both improved visual performance and long-term eye protection. Research over the past 40 years, by the leading centers of excellence for eyecare in America, validate the protection value of melanin. TAVAT acknowledges this research, and has chosen melanin enhanced lenses for all sunglasses… creating the perfect combination of performance, function, and design.

what is melanin?

Melanin is the naturally occuring pigment found throughout the human body. Its role is to protect us against sunlight damage, by filtering Ultraviolet (UV) and High Energy Visible (HEV) light, better known as “Violet-Blue Light”. Melanin is in fact the best natural defense against the harmful effects of the sun.

where do we find melanin?

melanin in lenses?

TAVAT’s sunglass lenses are infused with a synthetic melanin to provide the ultimate in eye protection, improving clarity, enhancing contrast, without any color distortion.

TAVAT’s sunglass lenses are inspired by the natural defenses of the human body against the sun. The synthetic melanin acts in the same way as natural melanin, just like a shield against both UV rays and up to 97% of the harmful violet-blue light (HEV). This means higher protection and better performance at the same time.

The differences between regular sunglass lenses and Polarized sunglass lenses are known.

TAVAT offers both types of lenses, specific to performance needs, but ALL with the addition of melanin.

Melanin makes the difference.

tlt: melanin

Normal Sunglass lenses that offer “UV-400 A, B & C Protection” filter 100% of the UV light passing through the lens and reduce, in general, a certain amount of visible light entering the eye. TAVAT’s melanin lenses achieve the above, PLUS filter up to 97% of the HEV light which reduces long-term exposure to the retina and therefore, reduces probable damage contributing to age-related macular degeneration (AMD) and cataracts.

In addition, HEV light, due to it’s high energy, is most scattered than other wavelengths because it attaches to moisture in the air resulting in haze. TAVAT’s melanin lenses, by filtering 97% of HEV light, eliminates this associated haze effect, allowing for enhanced contrast, true color & sharper image.

tlt: melanin polar

Light reflected from flat surfaces such as water, snow or asphalt in the road, generally is horizontally polarized.

This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as “glare” and can cause temporary blindness, disorientation and headaches.

Polarized lenses contain a special filter that blocks this type of intense reflected light, reducing glare. By wearing Polarized lenses, we eliminate most reflected light resulting in glare reduction, contrast enhancement, clarity of vision, and reduced eyestrain.

All opticians understand the benefits of coatings.

We believe that performance eyewear requires performance coatings which enhance the performance of the lens. TAVAT offers the following additions.

Anti-Reflective Coating

6 Layers of AR coating REDUCES BACK GLARE

Sunglasses lenses filter out light passing through them, but a percentage of light reflects back into the eye of the rear surface. It is estimated that 4% of light bounces off the convex surface and is reflected back into the eye. AR coating significantly reduces the amount of light being reflected back into the eye - hence Less UV, Less HEV and less ghost images. Frequently people complain about “back-glare” which is caused by this reflected light and the AR coating reduces this to tolerable levels.


Repels Water

Hydrophobic is a permanent coating, applied to the front and back of the lens, repels moisture and water buildup. This coating prevents streaks and sheens that remain on lenses and allow the lenses to be easier to clean.


Resists Smudges

Even the best lenses in the world don’t help if they’re dirty! Oleophobic coating is a permanent smudge resistant barrier coating that repels fingerprints and skin oils that build up on the lenses. This coating, applied to the front and back of the lens, allows the lenses to be easily cleaned without the blurring film that remains on ordinary lenses.

Anti-Static Coating

Repels Dust & Stays Clean

TAVAT Rx Lenses come equipped with a permanent Anti-Static Coating that is applied to the front and back of the lens. This coating reduces buildup of static electricity and its role is to repel dust so your lenses can stay clean.
