Optishade – the affordable photochromic lenses
We all lead busy lives, constantly rushing about from A to B, shopping, school run etc. So it’s no surprise that we get caught out from time to time in the bright sun without any sunglasses.
(I’ve lost count of the amount of times I’ve found myself squinting against the glare)
But no more!
Light intelligent, photochromic lenses have been around for years and a lot of patients seem to have a love/hate relationship with them. I’ll admit that before working in Optics I was in the latter group despite never wearing them!
But just before Christmas I decided I was fed up of being caught out with our temperamental weather and bought myself a new pair of Optishade glasses.
And I have to say they’re amazing!
So how do photochromic lenses work?
Photochromic lenses are embedded with tiny molecules of silver halide and chloride. In their normal state they appear clear.
When exposed to sunlight the UV creates a chemical process causing the molecules to move, change shape and absorb the light. This change in the molecules makes them darken to a sunglasses tint.
Once taken back indoors the tint will gradually lighten as the molecules begin to change back to their clear state.
What are the benefits?
For me convenience is one of the biggest benefits of the Optishade lens. The change in lens colour when outdoors is so subtle there have been times I haven’t even noticed it! I thought this would be annoying before getting them, it’s anything but. Even on overcast days there can be a lot of glare and UV around and it’s not until I take my glasses off I realise how comfortable the darkened lenses were making my vision.
What options do I have?
Optishade are available in single vision, bifocal and varifocal lenses and combined with either an Infinity XT or a Blue Shield coating antiglare.
They come in either a Brown or Grey colour depending on your preference and we have samples in practice for you to see the benefits.
