High-index plastic lenses are now available in a wide range of refractive indexes, higher than 1.5 up to 1.74.
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.

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.
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.
• 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
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.
Eyeglass lenses need to provide protection from unexpected impact, breakage, and from the sun’s harmful UV radiation. Trivex material provides high impact resistance while playing sports or working in a hazardous environment. The durability of Trivex material plus its stress-free characteristics make it an excellent choice for rimless (or drill mount) frames and any lightweight fashion frames that rely on lenses for structural rigidity. This material blocks 100% of harmful UV rays protecting your eyes from many eye complications.
Anyone who has an active lifestyle and expects: • Crisp, clear vision • Light weight providing maximum wearing comfort. • Strength and protection • Block 100% harmful UV light A perfect fit for children’s lenses… With Trivex material, children gain the benefits of impact resistance in addition to the great optical performance. Protection is provided without compromising visual performance for reading and schoolwork.
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.
PRIVO Polarized lenses provide better vision comfort outdoors. • They Neutralize the excessive brightness and remove all this unwanted visual noise blinding glare of sunlight. • They improve color contrast, depth perception and visual acuity for better eye comfort and safety. • Blocks 100 % of harmful UVA & B They are available in single vision and progressive lenses as well.
