What are transitional lenses?

Simply speaking, transitional lenses (known by optometrists as photochromics) change from light to dark, and vice versa, depending on the light levels surrounding the wearer. This style of lens provides the ultimate all-light, auto-changing lens solution for everyday wear.

Why carry 2 pairs of glasses when a 1 lens can do it all?

With today’s on-the-move lifestyle and huge developments in transitional lens technology, a wave of younger wearers and now driving demand along with the more traditional 45+ year market.

Whether you’re driving, working in the office, at home with the children or enjoying an evening out in town, transitional lenses work all-day for you. At Kathryn Anthony Optometry, we’ve seen a real demand for this style of lens, a trend backed up by our lens supplier Zeiss who’s research highlights that orders for transitional style lenses (already representing 11 % of all global prescription lenses) are growing twice as fast as the entire combined global sales of all other lenses.

Incredible photochromic lenses from Zeiss

For glasses wearers, we all know the feeling when the sun suddenly comes out and we’ve only our standard glasses on. ZEISS PhotoFusion X lenses, available at Kathryn Anthony Optometry, are the very latest in transitional lenses. Their ability to adapt to current light conditions, changing from clear to tint (various colour options available) is truly exceptional and provides what we feel is the ultimate all-light lens solution for everyday wear.

Available with the ZEISS PhotoFusion X are Grey, Extra Grey, Brown, Pioneer and Blue. All lenses can be fitted in frames from our leading brands, allowing you to create the ultimate frame/lens combination. Our dispensing staff will be delighted to show you examples of all the tints available when considering ZEISS PhotoFusion X.

Built in UVA and UVB sun protection

Yet another benefit of transitional lenses is that they offer enhanced sun protection all day long.

Our KA optometrist Jessica Watson says,

Transitional style photochromic lenses adapt to changing light by darkening outdoors and clearing indoors, while blocking 100% of UVA and UVB rays and filtering harmful blue-violet light within the blue light spectrum – offering all-round protection and comfort for everyday wear. Our lenses change dark within 25 seconds outside and clear in just over a minute coming back inside.
