Are Shamir Progressive Freeform designs say Autograph III radically different from say Tokai’s Resonas WS Freeform design?

I read there is molded freeform progressive lens vs digital designed freeform progressive lens? There’s a ton of reading on progressive lens designs and I am no optometrist.

To prescribe Tokai Resonas WS or Shamir Autograph III, do local optometrists have to be specially trained by Tokai or Shamir Singapore respectively to measure clients’ myopia + astigmatism + presbyopia + IPD + vertical fitting height to obtain accurate specific readings of clients’ vision?

A progressive lens is made using calculations of thousands of points on a single lens. The whole process of calculation, back surfacing, polishing, hardcoat application & multicoating varies across different labs. E.g. Autograph III from Shamir USA vs Shamir Singapore might have different performance & comfort due to machinery & processing differences. With that, its not possible to compare between both brands performance. Unless you just want to compare what they show on paper.

Indeed there's tons of readings and each brand/sponsored post will claim that their lenses are the best. That's what marketing does anyway. But, labs would usually give optometrists progressive lenses to try out. We would sell those that we are confident in having best comfort & least issues.

No training is provided by either companies for refraction. Troubleshooting support, yes.

Has Eye Zone Optical prescribe Shamir Autograph III with Transitions Signature VII and Tokai Resonas WS with Transitions Signature VII and Hoyalux ID Prime with Sensity + Blue Control? And compare them side-by-side.

How do these three progressive lens compare in terms of lens clarity aka light transmittance rate & the performance of their free form designs for a client whose eyes are ultra sensitive to peripheral vision distortion and is a first time wearer of progressive lens.

Client vision suffers -0.75 D myopia, -0.25 D astigmatism with +1.50 D presbyopia. Currently only wears single vision lenses when outdoors, none indoors [in office or home] and looking to pick a pair of photochromic progressive lenses that provide the least amount of distortion with the smallest region. Plus high lens clarity for brighter images in the far, intermediate & near distance. And with Transitions Signature VII.

Hi, Need some advise. I went to an optical shop and was quoted $800 for a American optics lens (with transition). My eyes power are 1100 and 950 with astigmatism 200 and 150 The shop owner said there is no need to add blue filter if you already on transition lens, sound correct? and I can only do 1.67.

Hey! Not necessarily transition don’t need blue filter! He might be helping you save cost or maybe your requirement doesn’t require you to have blue filter. Transition only helps to reduce glare when you are out in the sun but doesn’t help with filtering out bluelight or when you are indoor. Thus it really depends on whether your job exposes you to blue light constantly or if you feel that constantly staring at screens causes you to have fatigue/tired eyes!
Hope this helps!

There are many shops that still carries AO lenses. One reputable one that you can consider might be sintat optical at (old)Katong shopping mall. Or you can head down a few shops away to jamco to check it out too!

I'm thinking of getting new specs and there's so much to read up...

I'm looking at all the differnt photochromic lens, which one is the best in terms of darkness and fade back time? is transitions worth the price (compared to other brands with photochromic lens like zeiss, hoya) or is it marketing?

from youtube videos i've seen online, it seems like Hoya Sensity gets darker than Transitions 7, which i like. No tint indoors like the Transitions Xtractive too. But i heard that Hoya lens scratch easily?

also, is it true that photochromic lens help to block some HEV light too?

Hi! Photochromic lenses blocks UV up to 400nm. HEV light is from 400-450nm, with 400-420nm being the most damaging to our eyes.

Unless the photochromic lenses have HEV blocking properties, otherwise it does not block HEV

Honestly, it depends more on the fit of the frame to decide if its good. If you have high nose bridge then you are in luck whereby you can wear many types of frames e.g. rayban wayfarer , certain oakley models and etc.
Clubmasters looks good aesthetically thus if you are comfortable with it then go ahead to get it. Clubmasters also have the nosepads to help sit better for the buyer.

My wife just went to a shop and bought a Zeiss single vision lens, 1.6, transition with blue light filter. It cost her 500 for the lenses. Her short sight is 400 with astig of 100. Is that price around market price? Just felt is abit high.
