Transitions, Progressives, EmPower, Oh my! Optical terms can be quite confusing. Let’s see if we can clear three of them up.
Transitions are automatic sunglasses. When the UV rays from the sun touch the transition lenses they darken. When the sun no longer touches the lens, it lightens. Transitions work great for going in and out of doors hands free; they “transition” automatically.
Progressives are a no line bifocal. When you look through the top of the lens your distance viewing is clear, when you look through the middle of the lens the intermediate (computer distance) is clear, when you look through the bottom of the lens the near vision is clear. Progressives “progress” in power from your distance to reading in a more natural flow than a lined bifocal.
EmPower are self adjusting bifocal. EmPower is the latest technology for a no line bifocal. With a simple touch on the side of the glasses, you can increase or decrease the power of your bifocal to meet your needs. (It is really cool how it works with an electrical circuit and liquid crystals!)
It won’t be long for emPower to include the Transition technology so you could have it all; an automatic sunglass no line bifocal with a self adjusting button.
That is all for now.
