HI material: 1.6: Recommended for a wide range of designs and purposes and for optical powers ranging from nearsightedness to presbyopia. Minimal chromatic aberration in the visual periphery and an ideal balance of properties such as impact resistance and thermal resistance. 1.67: These lenses are thin, light, and high impact resistance. The MR 7 TMoffers good tintability , ideal for sunglasses. The MR 10 TM offers superb thermal resistance suitable for high challenging temperature conditions. 1.74: It is suitable for users looking for ultra-thin lenses.

BRF Material

It is an advanced lens treatment providing protection from natural and artificial light sources present in our daily lives, from computer displays, TV, smartphones, tablets, etc.

Artificial Light Source

Thanks to the advanced technology of lens substrates and coating, PRIVO BRF with Armor blue cut coating blocks up to 98% HEV blue light in the 415nm – 435nm range, up to 3x more than a standard clear lens.

WHY IT’S SO IMPORTANT FOR YOU?

Tired, dry eyes, eye strain, insufficient visual contrast, and headaches, all might be symptoms of long exposure to blue light. It increases the risk of macular degeneration and retinal disease. Children are also more exposed than adults to light. Because their eyes are more transparent and not fully developed, they are less protected from the dangerous effect of UV and Blue-violet light.

Exposure to Blue light during the day

Sleeping

Decreases in melatonin cause a disruption of the sleep cycle.

Fatigue

Eye strain, tired eyes, dry eyes, and might be symptoms of long exposure to blue-violet light.

AMD

Part of the blue light was recently identified as harmful to our retina. It can accelerate the appearance of AMD (Age-related Macular Degeneration).

CATARACT

UV light is dangerous to our eyes as they are to our eyes as well. Its effect accumulates over our lifetime, accelerating eye aging and the appearance of the eye’s lens Cataract.

TRANSMATIC

TRANSMATIC: Photochromic lenses accommodate the fast color change from indoors to outdoors and back. It reduces the glare and filters UV light. These lenses are available in 1.50, 1.61, 1.67 indexes in both grey and brown colors. All indexes are also available in TRANSITIONS 8 which offers optimum vision, comfort, and protection all day long.

TRANSMATIC lenses contain photochromic dyes which cause the lens to darken when exposed to ultraviolet (UV) rays from sunlight. When the UV light diminishes, the lenses fade back to clear. As outdoor light conditions change, the level of darkness adjusts, creating just the right level of tint and allowing just the right amount of light to enter the eyes at any time. The higher the UV, the darker the lenses get. The lower the UV, the lighter the lenses get.

TRANSMATIC lenses designed to protect your eyes 100% from harmful UV 400.

• The TRANSMATIC UV Filter blocks 100% UV 400 rays • Highly recommendable for the ones who spend most of their time both in indoor and outdoor • These Lenses are suitable for all age groups with moderate and higher prescriptions • Vast material availibility in brown and grey colours • The TRANSMATIC UV Filter blocks 100% UV 400 rays • Highly recommendable

TRANSMATIC BLUE RAY FILTER (BRF)

Photochromic lenses are only designed to filter UV light which is considered too harmful for human eyes. Digital blue rays are also affecting our eyes and may cause retinal problems. That is why TRANSMATIC BRF lenses work on filtering both; UV & harmful blues rays. TRANSMATIC BRF is adding more value. The blue Ray filter is built in the lens material and not only in the ARmor bluecut coating. The Synergetic effect of this combination assures better protection for your eyes from both Harmful UV and Blue Rays emitted from LEDs. protection for your eyes from the Harmful Blue Rays emitted from LEDs.

POLARIZED

Light travels in all directions and it reflects randomly off shiny surfaces (such as , snow, even cars, or buildings) produces glare. This glare reduces vision quality as the perception of color and contrast will change. Polarized lenses do what other lenses or lens treatments can not do.
