Good morning, Yes this is normal. Due to the fact that as the lower portion of the lenses having their degree lowered by about 0.40/0.50 thus this effect will cause the peripheral distortion.

Totally fine, it will train you to get used to digital lenses and progressives in future!

Not really normal for a pair of anti-fatigue lenses.

the slight reading boost at the bottom shouldn't cause any distortion on the sides.

Its normal for bottom to be slightly blur(Due to reading Boost), but the sides shouldn't be blur

Always remember that a pair of glasses should be there to assist you in achieving comfortable vision and not make you feel uneasy

Hi, as Long as there is a reduction of power or added [+] in such lenses. There is bound to be distortion. However how it is being viewed is entire based on the sensitivity threshold of the patient wearing it. Just like how you add more + to a progressive. Soft/hard design lenses will have this effect too. Especially if it’s hard design lenses which eyezen is.
Even at such Low add I would say maybe 10% of individuals would feel it.

Tokai lutina hev cut off. For the general public awareness. 10-17% is the standard uev cut off for blue light filter lenses. 100% cut off is just for UVA and UVB.



As mentioned. ALL blue light ABSORB lens does the same “magic” of being able to cut off the laser pen test. Important thing is to choose the right type for the patient job/need.

Pardon my drawing. But this is a brief representation between the difference of hard and soft design lenses. You can consult your optometrist/optician for more info too.
This designs applies to lenses which allows you to see far/near/intermediate e.g. zeiss digital lens, EnergizeMe, hoya sync, eyezen and more.

yup agree that a reduction in power will lead to some form of distortion, but there are lenses in the market that are able to hide the distortion so well that users can feel almost none of it. Just happens that the brand in question is not one of these. 🤭

Well, it used to be that way(Soft/hard) for alot of years until the introduction of Camber lenses.

To simply put it, camber lenses works on the front surface curvature to negate distortion from the progressive design on the back. Resulting on a pair of progressive lens with minimal distortion.

Coming from myself and not in support of any brands in the market. I would say that even the best lenses in the market, will have their own share of satisfied and dissatisfied patients.

I understand there are places that supports certain brands which is totally normal but the population should be educated to know the limits of lenses can be done. Expectation have to be managed and we can't paint a perfect picture for them least it fails to live up to it.

*note* The "big boys" are not using this technology yet
I believe this is something new even to me!

''big boys'' May/may not need to come out with something like this as their progressives/digital/anti-fatigue are serving the population well though they might in future.

I will end my piece over here by reiterating my point to all the forumners here.

There are many lenses in the market, claiming to be better/best of all at different cost. But do your due research or if not ask your optometrist/optician that you trust, to recommend you a lens that fits your need and not something which is too overkill.
Sometimes there will be BOMbastic terms are thrown at you so as to impress you and we will be like... Errrr ok la since sounds so good then take and easily causing you splurge on more than you need. Do take note of such instances and always reject if you feel that it(the lens) is too overkill. A trusted Practitioner will always recommend you what is needed and not what is better for their sales pocket.
Also there will always be a certain magician performing some tricks, to show you some gimmicky tool but in the end, all road(or in this case all lens) leads to Rome. It does the job but again, does it fulfill your needs in your workplace/job.

After these few days, i hope to let you guys know, i am just a worker not a boss. Here to prevent others from getting chop carrot. Don't have to visit my workplace but i can always recommend you places that are closer to your area of convenience. I have absolutely no commission promoting or talking about any brands too.

Cheers and thanks Eyezone for sharing.

Hahaha, then unfortunately it’s the habit that has to be changed.
Even with hoya HVLL coating also can get scratched. But if given a choice, based on popularity vote, hoya wins.

Thanks for the reply


For -5.5 both eyes should go for what index?

I've been using 1.67 all my life but I'm wondering if 1.6 is enough?

It depends on your frame size, bridge and your pupil distance. All this plays into account the size/weight/thickness of your lenses. Generally I recommend 1.67 but if you wish to use 1.6 it is alright just thicker/heavier lenses(for the more sensitive individuals).

Thanks for the reply

Ok, I'll stick with 1.67 then


For blue light lens like Hoya blue control, does blue light get reflected on the back side of the lens into our eyes?


saw these posts abit worried

I come across a video showing blue protective lenses reflecting UV radiation into the eyeshttps://www.youtube.com/watch?v=KCiT...ature=youtu.be

A thread talking about ithttp://www.optiboard.com/forums/show...l=1#post510318

Seems like they are saying that lens coating on the side near the wearer will reflect UV into the eye. Now I am wondering if the blue protective lenses actually harms the eyes more.
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.
