Hoya lenses are double aspheric from lifestyle v+ onwards so yes it will be slight thinner. Depending on which Brand too, zeiss aren’t. It will be safe for you!

I guess choosing the Big Three brand should be safe enough? Big Three = Hoya, Carl Zeiss, Essilor. In the past, hoya have the best reputation for progressives, still the case now? I tend to think that zeis and essilor dont produce lens that are as thin as hoya, nikon, seiko even though having same index?

If I remember correct, the Varilux 1 for 1 promotion. For 1.74, the free pair will be 1.67. You gotta check with the optical shop and some shops has extended promotion date despite it ended on 31 May.
Yes you are right. As 1.74 index is unable to do Tinting thus the free pair will be 1.67. Great that you mentioned it as i missed it out.
And yes only certain shops still have this promotion extended til end of June.

If im not wrong, lifestyle balansis is also double aspherical design?

Based on my wearing experience and my prescription for hoya SV lens, difference between single aspheric and double aspheric of the same 1.67 index is about 1mm thickness at the side of the lens, regardless of shape and size. And difference between 1.67 index and 1.74 index is a further 1mm thinner.

For me, cost ratio not really worth it to get 1.74 index. I only get 1mm thinner but cost like about 40% more.

That’s right on second point. Iirc lifestyle V+ then is double asph. I can check on that again.

Usually we will give a rough estimate on the thickness to the customer and let them know the difference in lens thickness, then they calculate if it’s worth the extra. But again there are and there are not those that are willing. Once again frame size plays a part in thickness of the lens.

our lenses have 2 surfaces - front and back
usually the aspheric surface is only on one side.
double aspherical means = thinner lenses.

double aspherical lenses really is thinner and lighter - personal experience.

Cheapest go to either Ngee Ann optometry Center or Singapore poly Optometry center. Call in advance to book appointment, then pay 5dollars for the check.

I am looking for some frames only. Want something good value and don't care about brand. Should I buy online or from shops? Any recommendations on places to buy?

Hi experts out there, recently I saw few postings in Carousell selling Lindberg frames for eg Model 9707 at $280, 9711 at $280 and others. Are they genuine? Thanks in advance.
