I am no expert, I am just sharing that the video shows that the blue rays are reflected to the eye. 1.33min of the video shows a quick experiment that the inner lens side reflect blue rays that cause the dummy eye to have a burnt area where the blue rays are reflected. Video total did 3 experiment with same results showing dummy eye burnt.

I understand that the UV coating is on the outer lens and inner lens surface of prevencia lens, I guess maybe double side UV coating causes reflection on the inner side even though Prevencia coating is on the outer surface only.
Are u discussing abt harmful effects of UV coat or prevencia coat now? 2 different coatings leh.

Anyway most lenses have UV coating nowadays and im seldom outdoors so UV coat not such a concern for me. Prevencia coat really did help me see better though. Less glaring. Less tired. More relaxed eyes.

I ordered mine at an optical shop. Guess the lab will make for me. How long it takes i guess depends how fast the worker handling my lenses works lor. If he eat snake then wait longer.

Eyezen is more expensive by $50 than Prevencia (both 1.56 thickness for low myopia and asti), according to the crizal price book that the sales person showed me.

Maybe you have some promotions or high degree so pricing is different.
Yes mine is RX. Last year mine cost $570. This year inflation drops. I oni pay $350 got crizal, prevencia and zen. All in one. I hope my lao hua comes late cos will need to pay 1k+

yes, I also experience the same thing as you initially. Just need to get used to it for a week, if after that still the same effect then you'll have to go back to your optician for advice.
I'm also having this issue. Not sure whether is it eyes not used to HOYA lens. Been wearing it for few days and at times eyes cannot focus well, also feel slight giddiness.
Previously was using Crizal without any issues.

I am discussing about Prevencia reflecting more UV into the eyes. The video shows blue coated lens reflection causes stronger UV reflection towards eye than normal non blue coated lens. Blue reflected areas shows burnt area on the Photochromic lenses after some time. Photochromic lenses acting as eyes on the dummy prove UV rays presence as it turns dark on the areas that blue light is reflected onto it.

I agree Prevencia coat helps me see better and less tired and feels good, but if more UV rays is reflected into the eye, I rather use non prevencia lens. Some indoor lighting do give off uv.

But prevencia coat is on the outer lens surface, how to reflect into yur eyes??

And the man in the video is doing testing on hoya blue lens and not essilor prevencia lens. Hoya has blue coat on both sides of lenses so thats why that guy doing tests on hoya lens.

I put a piece of white paper on table, put inner lens side (the lens side that is nearer the wearer eyes) facing table and I shine a light towards inner lens side and I see purple reflection off the inner lens side showing up on the paper.


I guess even though the prevencia coating even is at the front part of the lens, the back side also have same prevencia effect since the lens is transparent.

I am just a normal user sharing my thoughts, so I may be wrong on how the exact lens work vs my assumption. The guy in the video shows that the purple reflection is reflecting UV rays, so I am assuming maybe that is the same with my Prevencia too since it reflect purple rays at inner side.

While looking for more info about hoya bluecontrol lens, it seems like I do not see anywhere say that blue control is coated both sides. I see this hoya bluecontrol video the lens diagram seems like showing only the front part is coated blue, 0.40min https://www.youtube.com/watch?v=czha27eUcfE

My optician told me that hoya blue coat on both sides of lens while essilor prevencia on one side only. She is the professional so got to trust lor. But im seldom outdoors so im not worried. If u worried better wear sunglasses or cap much better. For me im indoors more often so blue light more of concern to me.

Hello all,

Im mid 20s this year. Looking for lobang to get fashionable frames and good lenses. My eye degree quite high, about 900 plus. (My eyes not suitable to do lasik when i went for the test earlier last year...)

Anyone can recommend a place for me to make new spectacles? Costs not the biggest issue, since I can claim the partial amounts from my compny

just did mine at holiday plaza, sun ray @ level 2, beside a hair product shop. i did a titanium frame + "good lens" (as stated by the owner cost 160 myr, while normal lens is 80 myr) for 450 myr.

while my gf made a cheap and very light plastic frame; 150myr. Lens, 250 myr for 1.6 HI bcos her degree is ard 800. so total is 400 myr.

i feel that the owner is not a professional optician, he read out the number and alphabet while giving me an eye test, LOL.

just wondering is it consider cheap?
