Medical Forum / General / Vision / September 2005Rimless with High Rx - some say yes and some say no
I am in Houston Texas USA My Rx is: R -7.5/-0.75/096 L -7.25/-1.25/097 Many of the traditional shops in town say rimless won't look good even with the super high index lenses. Other "specialty" shops say they specialize in it. Soem have even said they have lab people custom grind them to make them as thin as possible w/o compromising safety much. Fortunately one of the shops say they do these enough that I should be able to see a sampe near my Rx soon. In any case, what is the deal? Ehat should I expect? >I am in Houston Texas USA > [quoted text clipped - 12 lines] > >In any case, what is the deal? Ehat should I expect? Eye of the beholder. The thinnest lens for this Rx will probably be Sola's Vizio/atoric/1.67. Another good choice that has a better AR coat than the Vizio is Hoya's 1.70. Both lenses should be less than 5mm thick in a small frame. Do not "roll the edges". Polish is ok. Must be AR coated. Ask to see an example in the type of frame that you are interested in.

While they are ok in thickness I'd like something thinner. Is this the best they can do in the USA in the 21st century? Also, the AR coating has completely failed after 4 years. What about Essilor's products with Crizal Alizé ? If I have to I am willing to fly to Japan or wherever for thinner lenses. Where can I get the thinnest without getting too ridiculously unsafe. Keep in mind I will have a 2nd or 3rd pair of glasses for situations where safety might be an issue. > >I am in Houston Texas USA > > [quoted text clipped - 30 lines] > "An expert is a person who has made all the mistakes that can be made in a very narrow field." > - Niels Bohr >Thanks, I have what I think is Hoya's 1.70 or 1.71 that I got in 2001 >on frames sized 43.

The newer coatings have a very low failure rate as long as the coatings are used on approved (generally non-scratch coated surfaces) lenses. >What about Essilor's products with Crizal Alizé ? I've been using Crizal for almost 5 years without one failure. Alize is the same coating with an improved hydrophobic layer that is very easy to clean, maybe easier than uncoated lenses. Zeiss Advantage is its equal along with a handful of other manufactuers. >If I have to I am willing to fly to Japan or wherever for thinner >lenses.

You don't have to go that far, north of the border will do. 1.74 is the thinnest plastic and 1.9 Zeiss glass is the thinnest period. Define unsafe.

The 1.9's can't be done in rimless right? That is my goal - super thin in rimless. My 1.70s are ok in my current rimmed ones. What is safe? In these glasses will be no sports or aggressive activity - I will use contacts for that, even though they bug my eyes a lot. My main concern is for instances that are out of my control, such as an airbag in the car smacking me in the face. Could that shatter the lenses? |
