Transitions XTRActive new generation wearers are satisfied with the vision experience 8 :. Lens changes accelerated and mirrors simulated for demonstration purposes. New powerful dyes and the exclusive nanocomposite matrix power Transitions XTRActive new generation lenses to provide you with the best extra darkness and the best extra light protection. Transitions XTRActive new generation lenses are recommended for wearers who are very light sensitive or frequently exposed to bright light.
They deliver the best extra darkness and the best extra light protection 1 from intense light indoors and outdoors, even in the car. Transitions XTRActive new generation lenses are the darkest photochromic lens in the car and the only photochromic lens achieving category 2 levels in the car. What are Photochromic Lenses? Photochromic lenses darken to a sunglasses tint when exposed to sunlight, or UV ultraviolet, and return to a clear state when indoors, away from UV light.
Often referred to as transitions or reactolights, p hotochromic lenses are made of many lens materials including plastic, glass or polycarbonate. They are typically used as sunglasses that conveniently switch from a clear lens indoors to a sunglasses depth tint when outdoors, and vice versa.
They typically take around 30 seconds to fully darken and between two to five minutes to return to a clear state. Photochromic lenses were created in the s at the Corning Glass Works Inc. They will return to an almost clear state within two minutes and be fully clear within five minutes, however, excessively high or low temperatures can affect this timeframe.
Photochromic lenses are an extremely convenient, cost effective and beneficial purchase for a number of reasons, although, there are some weaknesses. There are pros and cons of photochromic lenses and sunglasses, including those listed below:. Reaction Times — Although photo lenses reaction from clear to sunglasses is quite quick, typically within 30 — 60 secs, the reversal takes a little longer as much as 5 minutes depending upon the temperature of the lens which could be dangerous if entering a dark room or certainly inconvenient at best.
Photochromic Lens Temperature Dependency:. Cold weather also increases the time taken to return to a clear shade. Plastic photochromic lens molecules of silver and halide are usually layered or embedded evenly onto the surface of the lens providing an even shade of tint when darkening.
Glass photochromic lenses have the molecules contained within the glass and this can sometimes cause an uneven tinting effect on a lens with higher prescription due to the different thickness of the lens from one edge to the other. Transitions XTRActive lenses darken behind the car windshield.
Transitions lenses are an enhancement over clear lenses, helping to protect from harmful light indoors and especially outdoors. Sunglasses have a constant non-light and non-temperature dependent dark tint, making them more ideal for prolonged outdoor activities. Transitions lenses are ideal to use as a replacement for clear lenses in conjunction with sunglass wear. Polarized sunglasses are a great option for water activities or in full sun for maximum glare and light sensitivity protection.
Sunglasses are also more likely to have more wrap and face form than the ophthalmic frames you would use with Transitions lenses, which offers better protection from reflected or off-axis UV light coming from the sides, above, and below your eyes.
Who in your experience is light sensitive when stepping outside on a bright day or first entering a room with harsh fluorescent lighting? Everyone, right? Transitions lenses are ideal for auto-adjusting to changing ambient light levels indoors and out.
Some studies suggest blue light exposure may have significant retinal health risks. Blue light exposure from our computers, tablets, phones, and LED and fluorescent lighting has several negative impacts on the comfort and performance of our eyes:. While blue light is commonly associated with the devices that have defined our digital age, the sun is by far the largest source of blue light, giving off times more than digital devices.
It has several key advantages:. Twelve percent of all Americans including men, women, and children suffer from migraines. Patients with chronic migraines are well aware that harsh lighting not only can trigger an acute headache, but while they are experiencing a migraine, lighting levels that would otherwise appear normal can be extremely uncomfortable.
Many of my patients with migraines have already been wearing full-time lightly tinted lenses indoors to take the edge off of lighting from overhead fluorescents and computer screens. Early-onset wrinkles around the eye are predominantly caused by two things: sun damage to the skin and chronic muscle furrowing like that caused by squinting.
If you have a patient who asks you about their eyelid wrinkles; reports getting Botox or skin-rejuvenating laser procedures around the eye; asks you about blepharoplasty; or is investing or asking about ocular aesthetic procedures and treatments tattooed eyeliner, false lashes, lash growing serum users , then talk to them about wrinkle prevention.
Think about how many times a day you step outside to get to your car, walk between buildings, check the mail, or take the dog out.
