after done go back and inform them that it can be done

Yes, it is really common for them to do that.

User gardens got it right! Can be done. Price range about 650! With transitions. Maybe that shop staff is supporting other Brand’s. But from what I know, among big Brands, essilor can but hoya zeiss cannot!

Hi bro,

look around for shops that do lenti-cut on the lenses. This can make the lens thickness go down by another ~15-20%, even when using the same 1.74 index lens

Ok so far no much diff between kodak uv blue and crizal prevencia. But prevencia doesn't block sun glare as well as uv blue. Hmm

Zeiss has pretty good lens material, but 3D light progressive design is very basic. For that price, you could get similar material with much better progressive design (Less side distortion, less wavy effect, easier adaptability)

I've come up with some drawings to let more bros better understand what is UV/ Blue Block/ Blue Filter

Light Spectrum (Left side of chart being most harmful to humans):


Blue Reflect lenses block up to 30% across whole blue spectrum (~400-500nm)


Blue Absorb lenses block up to 94% of the high energy waves(up to 420nm), while letting the rest of beneficial blue light in.(~420-500nm)


disclaimer: straight lines are drawn to make it easier for me to draw :X Actual lines are not as straight as what is illustrated
Ok so far no much diff between kodak uv blue and crizal prevencia. But prevencia doesn't block sun glare as well as uv blue. Hmm
Prevencia is Blue block, Kodak UVblue is Blue filter

both are similar but not the same
