Optical Center Glasses And Eyeglasses?

Optical Center

Today that is the difference between progressive lenses. Like I said we count about as far as we can go and nobody and. I mean nobody has any magic pixie dust so it’s in lens design at Optical Center. Where one lens might stand out over another the entire concept of freeform lens design. Is putting the power of computing to work on a computer program. Takes everything into account lens powers all the sphere

Possible Lens

Cylinder axes add lens design or which style progressive lens we choose more on that in a minute. And the frame parameters then it accounts for everything and. I mean everything way beyond the comprehension that our little optician. Brains could never begin to imagine it. Takes all that into account and it creates the best possible lens for that individual then. We feed that information into the hardware notice I don’t say the perfect lens or. The best lens but the best. Possible lens and that’s an important distinction that’s the difference. Between education and marketing or advertising Oh before. I forget to make sure you go back and watch the one simple trick to choose the best freeform. Lens every time related to the stuff we’re covering here and plan a great. Let me grab the camera and bring it around here.

Optical Shape Design

Grab some play-doh and let’s talk some more about lens design. Before the introduction of freeform lens design in progressives came down. To a choice of hard design versus soft design, which we talked about in the last video. We always will have that cylinder present that unwanted cylinder off. To the sides and a progressive lens so let’s go ahead and put that in there and yeah. We always ended up with something that looked kind of like that right familiar. Shape and a look right distance intermediate near there and a hard design. Would have a deliberate sharp edge and the cylinder you would keep piling. It’s up if you will you’d be making it higher and more defined. You can see the three-dimensional look to it there it would give you more room. Or usable space to put your clear areas and that opens that up a little bit more but as soon as you went from this clear to

Convergence Lenses

So high this was so garbage that made people sick it caused. What was as swim? So what happened was they ended up doing soft designs. In which case you blend you make those transition zones. From that clear sharp optical more gradual smooth but you can see what happens what am. I do I’m losing corridor I’m losing reading I’m losing distance that was a soft design so you know. Everything today is a compromise. What free form does is it has the ability again through that computing power to examine. Where it can put the hard where it can put the soft so. Because of course, it is the way I wrote a smooth left-right in for convergence distance. What the lenses favoring distance intermediate near saw sports.
