Thanks for all the input!.......I believe I have decided to go with the Hoya Eyas 1.6 .....unfortunately here in the U.S. Nulux does not appear to be available, However, I still feel that the Hoya AR is slightly superior to the Sola Teflon....it also has a "lifetime of the prescription" warranty vs 2 years on Teflon (my last prescription lasted approx 8 years). So these reasons have given the edge to Hoya.
Thanks Again! I really appreciate all the help/suggestions!!!!!!!!!

> Sorry for the confusion.......This is for a single vision lens & I > believe the Essilor product he is recommending is their Thin and Light [quoted text clipped - 9 lines] > > Ricky There is no need to apologize, it was very clear that you were talking about SV lenses. The Rx left no doubt about that (thank you for posting your Rx).
Spectralite and Finalite are proprietary lens materials from Sola (who now owns AO). Spectralite is 1.54 index with abbe value of 47 and Finalite is 1.60 index with abbe value of 42 (pretty close to the Hoya Eyas 1.6 with an abbe value of 41). The Essilor 1.6 has an abbe value of 36. The higher the abbe value, the lower the chromatic aberration. Polycarb has an abbe value of 30.
Spectralite (like Trivex) has a relatively high abbe value, but you will have slightly thicker lenses at the edges (for a minus Rx) compared to higher index lenses because of the 1.54 index. If edge thickness is not a concern, then Sola Spectralite is a very good choice, as is Trivex (with the added strength). But since the Safilo E 7076 is a traditional frame (not a drill mount) then strength of lens is not quite as important (unless you wear your glasses while playing sports or in hazardous areas).
It looks like either the Finalite 1.60 (Sola or AO) or the Hoya Eyas 1.60 would be the best choices for your Rx. I might be tempted to go with the Hoya if you knew it was the Nulux aspheric model. Otherwise it would be a toss-up between Sola/AO 1.60 Finalite or the Hoya Eyas 1.60.

Sorry for the confusion.......This is for a single vision lens & I believe the Essilor product he is recommending is their Thin and Light 1.6........Also, the frame is fairly small, Safilo E7066. So with this additional info, would I be better suited to the Hoya Eyas 1.6 (Nulux EP) with their "superhivision AR coating" or AO XT16(Finalite), Considering my main concerns are clear & natural looking vision with minimal peripheral distortion. I have also heard of a material called Spectralite, would that be a consideration? The Hoya Phoenix & Trivex mentioned by Mark, sound interesting also, although high impact resistance is not a concern for me. Thanks for any info!

The original poster Rx does not specify any add (reading) power. Also, the AO XT16 that was mentioned is a SV lens design from American Optical. So I don't think the OP is looking at progressives.

I don't like the appearance of the Sola Teflon A/R coating. The residual blue is too strong, IMHO (although Sola thinks it is "pleasing"). I haven't prescribed enough of these to know whether, in the long run, it is as durable as others.
I think you can't go wrong with Essilor's Crizal Alize, Hoya's Super HiVision or I-Coat's Vivix Stainless. Zeiss' high-end A/R coats are excellent too. I hardly ever have patients that get these come back complaining that the coating has scratched up, peeled, etc.

For a prescription like yours, my first choice would be to fit you in a 1.67 modern progressive like a Varilux Panamic with Crizal Alize, but a Kodak Precise/Concise with Vivix Stainless works usually just as good for the vast majority of my patients. 1.67 Zeiss Gradal are "tops" too. :) Essilor has a 1.74 progressive with A/R coat out now too.
FWIW, I'm not a big fan of Sola or AO progressives, probably because I had bad experiences with the Percepta and the Compact respectively.

I recently purchased a pair of glasses at Walmart....They were the polycarbonate with their standard ar coating.The vision was great looking straight ahead,however,the peripheral vision was terrible & ultimately I ended up returning them.I am now in the process of trying another pair through my optometrist who is suggesting Essilor 1.6 lenses w/Crizal Alize......With what little I do know about lenses,this doesn't sound like the best option for me (O.D. -4.75 -0.75 145) (O.S. -5.00 -0.50 20). I thought either Hoya Eyas 1.6 W/Superhivision AR or AO XT16 1.6 W/Teflon AR would be a better match for me(both finished versions).....I am torn between the two...it seems like the Hoya AR coating is better than the Teflon but the AO XT16 seems like a better lens. I am very picky about clear sharp vision & cannot tolerate much in the way of distortion ie "fun house effect" I get dizzy & disoriented if the appearance is not flat & natural looking. Any thoughts would be appreciated!
Thanks! Ricky
