That's just part of the frame. Those kinds are OK. Those with separate nosepads will grow algae no matter how clean u are

Prevencia is not 100% blue control. I yhink more new blue control is coming up with new designs and technology instead of 100% block off blue. Basically the point is not all blue control is the same.

Stay cool about this hahaha just opening up some opinions. No research or reviews is wrong, just that we just need to stay open to more instead of just 1 or 2 before making decisions to cut off something totally

Hahaha ya r&d on the lenses. There are facts which proves the advantages. There are also useless information marketed. Not totally useless bro

Quote me some facts which u think are truths. Eg. Reduces strain with computer use? That's truckloads of bullsss IMHO. All their quoted studies are conducted by their own company. That's conflict of interests in research.

I have tried the lenses myself and i find it totally the same as normal lenses. Moreover the colour alterations caused by the lenses are disturbing.

Nothing personal. But my opinions are based on the independent studies that I have read. Blue control lenses are still a controversial marketing gimmick. Nothing is actually proven with randomised control trials yet

I myself don't sell these lenses to my patients. Because there is no real evidence based benefit. Benefits do not outweigh the costs of the lenses

Crizal Prevencia Lenses | Crizal Prevencia

Read this up. Prevencia is marketed for the prevention of eye disease caused by blue violet light. Studies they quoted are how blue light can increase the risk of these diseases. Nothing is quoted about these lenses reducing that risk. In simple terms. They just made use of a study on blue light causing diseases to back their blue blocking lenses. With no Randomised control trials done.

In fact normal CR39 lenses with multi coat is enough to block 100% UV. Blue light compared to UV causes less risk for these diseases. And the cost difference is huge. Not worth it at all

Hahah can I base on one research which says beneficial then I say its good?? There are always different researches with good or bad. Hahaha. Have u heard of the sleeping factor related to it? It may not work for every individual. Thats all im gonna say hahahah. Chill. Dun stereotype things hahahahah
Its yhe same as zeiss have better material which is a fact, but is every individual sensitive enough to feel it or not. Its really subjective. There are ppl who find the lenses useful some who did not.
I do not promote or bring down any products haha.

Quote me the study then. There are no trials conducted yet for the benefits of such lenses. Even the sleep factor. studies have saod blue light causes insomnia. But no studies have shown that blocking blue light with lenses help people to sleep better at night.

I don't stereotype. I believe in evidence based treatment. If you can quote me a randomised control trial for any of the quoted benefits, I will prescribe these lenses to my patients.

That's the science of optometry. I am not a hard selling optician. Singapore is a place where lens companies are not controlled on what they can advertise. That is why many people are misinformed. In Australia, they are not allowed to market so aggressively. No one will know about crizal. Its just like any other multi coats. Even their ESPF25 is a marketing gimmick. All lenses with multicoat already block 100% UV.

Haha chill. Very subjective bro. Like I said like zeiss lenses or any others. Thwre are ppl who love a certain lens to the other due to some reasons on its own. Our seannie bro loves his duravision hahaha. I believe some else will love the blue control and find less glaring due to colour differences or any other reasons. There are bound to be researches out there if we find. Chill out and let the guys decide hahaha
Anyway uv 100% dun come with all multicoat

Not a subjective matter. All these have to be backed by clinical trials . in singapore hard selling makes the most money. I am telling you that there are no such studies. Singaporeans need to learn to trust their optometrists and not lens companies.

That's why many people fall prey to such marketed benefits. Eyecare professionals have no choice but to advertise on non proven benefits because that's what makes them the money.

Overseas, they make money from the consultation alone Sp there is no need to make money from marketing gimmicks.

On the other hand physical properties like duravision are indeed researched into. Lenses are indeed tougher and less prone to scratches.

UV 100% come for all plastic lenses with MC. U can try it out on their UV measuring machine. I am telling you it has. I'm not asking if it has.

It is tougher no doubt. Its the material which is better compared to others I know. But only certain sensitive ppl feels it. Subjective like I said. Some can some cannot hahaha. I love duravision no doubt because of quality. Material wise in zess is backed with facts but not all feel the difference. Its just gives a solid guarantee to some which is good hahahah. buy zeiss if you guys can afford I reco. Hahaha.
Im gonna trust more optometrist more now after what u have shared with us!
Marketing vs personal experiences.
Thankss

Again one more misconception. Duravision is not a new material. It is a new hard coat created by Zeiss. Just makes the surface tougher. Doesn't affect the optics at all. Just less degradation to the surface with use. Prolong the lens life at most.

Lol I'm telling you to google. I know this from uni. All CR39 lenses are UV blocking already. Only in singapore they market UV coat and Multicoat. In australia lenses are still sold without coating. Cos they can't advertise on healthcare products. CR39 are inherently UV blocking. No need for coatings. Multicoat only reduce reflections on the lens surface that can cause glares.


UV coat again is a marketing gimmick. There is nothing more than 100% uv blocking. Since cr39 already block 100% UV, the uv coat is nothing more than an upsell gimmick.


One more benefit of multicoat is that the lens will not turn yellow that fast. The reason lenses turn yellow is because of its inherent UV absorbing capabilities

Just sharing the gimmicks that are always marketed in this industry. If you don't believe them, I can't help you further.

Crizal in singapore is marketed as the best UV blocking lens. Still all cr39 lenses block 100% UV. No such thing as best blocking. In Australia. Crizal is just another multicoat brand. Laypeople would not even know what is crizal. Over here. People ask for crizal when they don't even know what crizal is. Its just a multicoat branding

Inclined to side with your POV.
However, LED light does IMO, have a type of polarization that seems to affect how I see light sources (unfiltered, how do I explain this... like LED lighting behind a translucent/matte diffuser vs LED strip lighting)

Some of the works cited do seem reasonable, but maybe polarization is the way instead of looking at those "improved blue light blocking" lenses.

What's your take?

OTOH, PL-CIR is a thing, right?

edited out "hp screens" because most displays, they are polarized mildly
