WHAT DO THE COLORS REALLY MEAN?
Pink / Rose
Most commonly prescribed color of all the tints. Used for general cosmetic enhancement.
Yellow – (Shooter Lens)
Commonly used in low light environments to enhance contrast and aquity. Yellow attacks the shortest wavelength of the color spectrum (blue) to reduce “optical noise” caused by haze, mist, and smog.
Produces a transmission curve of light closest to that of the human eye. It is steadily gaining popularity in the U.S. sunglass market.
Brown / Vuarneti Style
A very popular base color for sunglasses. Color assists overall improvement contrast and acuity by managing the blue light spectrum.
Most popular base color for sunglasses. Color provides even light transmission through the complete visible color spectrum. Grey allows for perception of surroundings to be viewed in their natural shades.
Computer screens can be unkind to the eyes. As computers have become part of everyday lifestyles, we all have experienced computer “screen-itis” – the red and itchy eyes, blurred vision and dizziness all associated with prolonged computer use. A major university study confirmed that 94% of people working with computers experienced vision symptoms. CRT coatings from NACL combine UV blocking treatments with a high quality anti-reflective coating and special color tint. The result is a product that vigorously combats VDT glare and reflection, while magically improving contrast between characters on the screen for easy, comfortable viewing. Available in three colors and only on plastic lens materials.
Grey – for use with multi-color screens and black and white screens
Violet – for use with green screens
Blue – for use with amber screens
Lumasport – (shooting lens)
This lens was designed for sporting activities that demand high contrast including golf, tennis, hunting, marksmen, etc. Excellent for low light conditions (dusk or dawn). Yellow 2 tint with the Opticlear Plus anti-reflective coating.
Therapeutic Lens Series (T.L.S.)
Individuals who are ultra-sensitive to light will benefit from this lens. It eliminates 100% of the harmful ultraviolet light, 100% of the harsh blue light and 95% of the near infrared light. The TLS lens series is specifically designed to work in the 380nm to the 500 nm range commonly called the blue light spectrum. Filtration for blue light is necessary because it has the shortest wavelength and is easily scattered or diffused. Scattered blue light reduces oneâ€™s contrast sensitivity or washes out what is being viewed at the time. This is most common in people with certain retinal conditions or diseases such as: Retinitas pigmentosa, Diabetic retinopothy, Macular degeneration, Anfidia, and Glaucoma.
TLS 475 – “preventative” protection for people who spend time in the sun. May also be worn indoors. 40% absorption.
TLS 511 – Moderate protection for people with developing ocular symptoms. 50% absorption.
TLS 525 – Moderate to strong protection for senior citizens and sports enthusiasts. 60% absorption.
TLS 550 – Maximum protection for all people with advanced ocular symptoms. 70% absorption.
(All TLS tints are a solid brown/orange color and include a solid flash gold mirror.)
Blue Eliminator I & II
This lens is best known as the “blue blocker” style tint. These lenses have the same characteristics as the Therapeutic Lens Series.
Blue Eliminator I – Gradient tint – Dark brown at the top fading to orange at bottom.
Blue Eliminator II – Same as Blue Eliminator I with the addition of a Flash gold mirror.
Ultra Violet Filters (UV)
Plastic Lens – (clear in color) UV filter is absorbed into the lens using conventional tinting techniques. Lenses achieve 100% UV protection after treatment.
Glass Lens – (30% yellow in color) UV filter is applied as a coating to concave side of the lens.
