Transitions introduces Vantage, a polarized photochromic lens that creates a new category of photochromic lenses.
Making the impossible possible. That’s the message from Transitions Optical Inc. with its recent revolutionary release of Transitions® Vantage™ lenses with variable polarization and photochromatism.

So what makes Transitions Vantage lenses so revolutionary? Consider what it would be like to enjoy a lens that is clear when indoors, and then enjoy the comfort of a dark, variable tint with the addition of polarization when you step outside and the lens is exposed to UV. That would be great, right? That’s exactly what Transitions Vantage lenses do. In fact, they’re the first and only everyday photochromic lens that’s nearly clear indoors and darkens with increasing polarization outdoors for crisper, sharper vision.

FOUR KINDS OF GLARE Lens wearers experience four types of glare: distracting, discomforting, disabling, and blinding. There is distracting glare that is caused by lens reflections. Discomforting glare caused by everyday varying sunlight conditions can cause us to squint and experience eye fatigue. Disabling glare occurs when excessive, intense light reaches our eyes. The effects of disabling glare can cause long-term eye health damage. Blinding or reflective glare comes from light reflected off smooth, shiny surfaces such as water, sand, or snow. This reflective light is plane polarized.

Since 2003, Transitions Optical’s Research and Development team set their sights on creating the technology behind Transitions Vantage lenses—now known as variable polarization. One reason for this is because the eye cannot adequately manage all types of glare (See Four Kinds of Glare below). Transitions Vantage lenses with an anti-reflective treatment are the only clear-to-dark lenses that reduce all four types of glare.

Historically, polarized sun lenses are produced using a polarizing film applied in one of three methods. Older products use a polarizing film glued to the front of the lens. Newer techniques sandwich and cement the film between the layers of the lens. The third technique involves surrounding the filter when the lens is cast. The common denominator in all three techniques is the polarizing film. This means they all have a fixed tint and fixed polarization. When you think of polarized lenses, you think sunwear.

Transitions developed a fourth method to accomplish polarization. Unlike traditional methods using a film, Transitions Vantage accomplishes polarization on the molecular level inside the lens. Photochromic lenses have millions of UV reactive molecules. Transitions photochromic molecules have a chemical bond that breaks and the molecule opens when exposed to UV light activating in a random pattern. This darkens the lens. The molecules of a Transition Vantage lens darken in the same way, however, the open Transitions Vantage lens molecules align into neat horizontal rows create polarization—no polarizing film is used. The darker the Transitions Vantage lens; the more polarization.

The polarization efficiency of Transitions Vantage will vary from 0% to 89% depending on the amount of UV exposure and temperature. The lenses will return to a virtually clear state.

How do wearers like them? Results of research conducted by Transitions show that eight out of 10 photochromic lens wearers were satisfied with the outdoor experience of Transitions Vantage lenses. Nine out of 10 photochromic wearers were content with the indoor clarity of Transitions Vantage lenses.

Transitions Vantage lenses are available in gray, single vision, and progressive addition lens (PAL) designs. The single vision Transitions Vantage is available in 1.5 CR39® lens materials, polycarbonate, Trivex®, and 1.67 resin. The PAL version is available in polycarbonate, Trivex, and 1.67 material. Expect numerous additional designs and line extensions throughout the year.
