Just to chime in on the Shamir Duo.. It's essentially a pair of bifocal without any lines. It only has the distance and reading zones, thus it wouldn't be very helpful for your computer screens where we consider it as the intermediate zone.

While it can technically be configured to mimic an office lens, it lacks the smooth progression from your screen to something up close. Thus I wouldn't recommend it in this instance.

So does all progressive lens has this intermediate zone?
I do have difficulty reading computer and my lens is from Korea .

It has a yellow tinge that I find that it's like a filter when reading though I am not conscious of it when viewing faraway things.

Hi!

All progressive lenses have intermediate zone, the height and width of the clear portion depends on the lens quality, prescription and frame design.

Yellow tinge should probably be the effect of Blue Coat. Generally good to use if your eyes are sensitive to bright light.
PMed you a 1 min read to understand the various types of Progressive lenses & office lenses

To add on to what Optometrist mentioned, viewing on the screen comfortably also involves your desktop ergonomics (ie. Chair height, monitor height, table height, viewing angle and distance, ambient lighting conditions, screen brightness etc).

If you do spend a good amount of time on the screen and require a wider viewing zone, a pair of office lenses may be something that you can consider to complement a pair of progressive lenses.

Can't really go wrong with office lenses from the big boys. I personally prefer to go with Asahi Lite, to maximize comfort for my clients with customization.

My current glasses len is Ashahi but I don't have good experience with this particular brand. I took very good care of my glasses but around 1 year plus mark, coating starts to come off..

650 for your prescription is a pretty decent price. RRP is $700 for 1.74 Zeiss Single Vision Superb Asiana.

If your main concern is the coating, Can consider Hoya Nulux Classic 1.74 HVLL ($580) instead. Hoya is well known for their long lasting coating

Hi, thank you for the reply.. Sorry I got my prescription wrongly, the last time I checked it was quite a few years back. Just did a check on my prescription a few days ago:
R: -9.00-3.25 x7
L- 7.75-3.50-165

I was offered either Hoya or Carl Zeiss, quoted the following including frames:
1) $700: Carl Zeiss 1.74 Asiana with blue guard
2) $800: Hoya 1.74 Nulux V Full control

For comparison, I made a pair of glasses with the same prescription using Ashahi lens 4 years back and I paid $600.

Another concern is, my degree increased by a bit, like 50 for shortsightedness. but optometrist said can maintain at current degree. reason being optometrist doesn't want my eyes to be too strained when I see things close-up eg reading. Though I won't be able to see things far clearly should I stick to my current degree. In this case, is it wise to stick to the current degree?

Last yr, after I have done with my cataract surgery, I went to few optometrists and willingly pay them around $30 for an eye check-up in order to test their skill and experience their optical machine. Some of the shop I visit included those recommended in this forum.
My conclusion is that if you want to have best vision for your eye, the follow conditions is needed.

Number 1:
You need best lenses.
For clarity, I rank Zeiss and Nikon in first tier. Hoya and Varilux in second tier.

Number 2:
You need a skilful optometrist who can afford to give you hours to do eye test, esp for complicated cases.
Otherwise, your skilful optometrist might choose to cut short the time for some reasons and you also don’t know you are not getting the best unless you go to seek another optometrist.

Number 3:
You need optical shop that are willing to spent ton of money to be fully equip to make the most customized lenses.

Because the top tier model of each lenses brand has become fully customized. These lenses required additional instruments to take more parameters into making the lenses. Some of these additional instruments can be very expensive which I observe most shops are not willing to procure.

Then you know what they do? They go use ruler to take your measurement. One shop did that to me when I ask for Hoya Mystyle V+ progressive lenses. Actually, if he doesn’t have the instrument needed, he should be honest to tell customer.

Number 4:
Our ability to communicate well with optometrist.

Hi, which shop would you recommend then? Thank you!

Pretty good prices

Do however note Zeiss blue guard and hoya full control are 2 different things

Zeiss Blue guard is inbuilt into lens material, absorbs up to 94% HEV (harmful blue light)
Hoya full control is a layer of blue coating. reflect up to 30% across whole blue spectrum.

If your work involves alot of near, then maintaining at the same degree is a wise choice.

Manufacturer warranty is 1 year. but if within 15 months, still able to push for a free replacement.

Haven't been seeing much coating peel at my side though *touch wood*

Hi thank you for the reply. In that case in terms of coating, scratch and water resistance, is Hoya or Zeiss a better choice?

Hmm thanks for the clarification, not very clear on how blue guard of zeiss and full control of hoya works, but my main concern is blocking the blue light.

I do use computers at work but not throughout the day from 9 to 6. But I do use a lot of handphone, tablet and laptop at home so I think it's better to stick to my current prescription in this case then?

Thank you!

Hoya's HVLL coating is well known to be very durable.

Seems like you do alot of near work, stick to your current prescription would be good.

Blue Reflect lenses block up to 30% across whole blue spectrum (~400-500nm) & are generally much yellowish


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). These lenses have an almost not noticeable yellow tint.

Lens coatings have come a long way, and I must say that the coatings offered by the big brands are really impressive. There could be many factors why coatings don't last as long as one would hope.

The most obvious and common factor is due to the handling. More often than not, we use our clothes, tissue or just about anything 'soft' enough to wipe off those dust and grime on your lenses. Most lenses these days are made of plastic, so even if you have the best coatings, it still doesn't change the fact that plastics are really soft and easy to scratch. Once the coating is scratched deep enough, this could be the starting point where it can start to peel.

Temperature changes can be a culprit too, and they often result in lens crazing. Crazing is commonly referred to as coating cracks. For example, sustained high temperatures (eg. putting glasses on the dashboard under the sun or on an electrical appliance) or even repeated temperature changes over a long period of time (eg. cold room to hot sun) may contribute to the weakening of the lens coating.

Cleaning the glasses with unknown detergents can be a risky thing to do as well, so sticking to water and diluted pH-neutral hand soaps will be your best bet to remove the excess dirt and grime from the lenses.

I just use hand soap and my body towel to dap.
Not rub.
