Today, our office got to meet a very knowledged sales representative from one of our labs. He wanted to discuss with us the revolution of wave front technology, otherwise known as digital/free form lenses. This is nothing new to us, but it may be for you.
If you wear a progressive style (no line bifocal) lens and are not a big fan of the distortion that you may see on each side of your lenses, you are in luck. There are many different manufactures who have their own sleek design to free form. Today we learned about Varilux products. Some of you may be used to hearing this brand, since Varilux has been around for quite some time now.
Free form lenses are different from regular progressive styles, because it is made more customized to your Rx. The original progressives are pretty much cookie cutter in the optical world. Think about a hockey puck.. take your new and not to mention fabulous frame that you get here, cut the hockey puck to fit then frame, plop it in and try to find your best Rx through a sweet spot about the size of a spot on your miniature dog.
Digital lenses are made a little differently. They are made froma single vision blank, and they digitally grid the reading power on the back side of the lense with a...wait for it ladies, diamond point cutter. Savvy huh? This process helps make the lenses flow nicely together to create less distortion in your lenses. It also widens the "sweet spot" so you won't have to look like a crazy person moving your head around until you find it.
The good news is these digital lenses are also made for single vision! These are good for anyone who has a higher Rx. If you are used to glasses that make you look like you are wearing coke bottles or shrinking machines, it all changes for good! I have a very high plus Rx. All my life I was used to having lenses that made my eyes look 10 times as big as they actually are. I used to wear only contacts because I did not want to deal with having to look funny. Now that I have tried these lenses, not only do my eyes look normal, but I can see like an angel. I feel like I can see more clear than with my contacts! Not to mention that my eyes don't hurt from always wearing contacts. The single vision digital lense is bi-aspheric, meaning they enhance the performace from both sides of the lens. High Rx have a sweet spot as well. With this lense you can see through the whole lens clearly!
Things really do get better with age...don't they?
