The Spectacles Thread. - Part 2

Anyone tried acuvue moist multi focal contact lens for your near sightedness?

Is it true such multi focal contact lens only come with pre-fix Low, Medium, High range?

In other words, contact lens not as customisable as compared to normal progressive glasses?

Yes Acuvue Moist Multifocal only comes with 3 pre-set addition (lao Hua) ranges:

Low (+1.25): +0.75 to +1.25
Med (+1.75): +1.50 to +1.75
High (+2.50): +2.00 to +2.50

Yes that's correct too, usually for multifocal contact lenses, we often tell our patients that it is a “90%” functional vision, and not a 100%. There's often some compromise needed for both the distance and near vision to be good. Like maybe one eye (often the dominant one) fitted with more distance, and the non dominant eye being more for near vision. But multifocal lenses are often better than single focus lenses.

Unfortunately I didn't get to ask her if more premium means Tokai, just that it wasn't their basic ones that came with the $100 for 2 pairs promo

From my understanding premium lens probably refers to progressive, BLU premium or Tokai but maybe you can double check again.

For myself I went for an eye test at their store and then ordered online. My eye test prescription did not have any reading for ocular centre, but I did not tell them what kind of lenses I will be going for either. I ordered Tokai lens + Ultra Thin 1.76 Index and they just processed my order without any reading for ocular centre. So I guess Lenskart just estimate the ocular centre based on pupillary distance?

i have a few questions, seeking some expert comments! (my degree: R: -2.00, -0.50, 53; L: -3.75, -1.25, 168)

1. i am using zeiss 1.6 stock clearview lenses now. might an upgrade to either zeiss single vision asiana or individual make a noticeable difference in terms of 1) clarity, 2) comfort, 3) peripheral vision, that makes paying like $300+ more worth it?

2. my new kodak evoblue single vision lens' (exact same prescription) peripheral vision is noticeably worse than the zeiss clearview. previously i did not notice that the periphery is that bad even on the cheaper OSS lens. is it just that these kodak lenses might not be so good or could there be more to this? (all the frames i use for the three spectacles have very similar builts: ic berlin (OSS), lindberg (zeiss), reykjavik eyes (kodak))

3. do all opticians in singapore take your optical center position when making your lens? am thinking of buying online and understand this can't be done and only your PD can be taken into account. but at a lenskart shop i asked the staff and she said they don't take the OC and only your PD, except for their more premium lens. which makes me confused as i thought taking your OC is important even for single vision lens wearers like myself..

1. The difference is really that extra ~10% clarity in terms of customising your individual frame parameters (vertex distance, pantoscopic tilt of your frame etc). I have a colleague who compared the difference between even Clearview and Smartlife SV and they have said that there really is a difference. Its not that the former is not clear, its just that its just sharper with the Smartlife SV lenses. I would say go, if you are extremely particular with your vision and if its within your budget!

2. Zeiss Clearview lenses are known to provide one of the best visual quality compared to other regular single vision lenses. They minimise the peripheral distortion to a large extent by altering the peripheral curve of the lenses. Which is why you have so much difference when you swap over. Kena poison by Zeiss lenses liao hahaha.

3. Most opticians/optical shops will take your pupil distance which is a pretty standard thing, however not all may take the pupil height (which may be what you consider as the optical centre). Its not as important for single vision lenses as compared to lenses which are customised or progressive lenses. Nonetheless, we try to on every patient as its a good practice to still take both PD and pupil height measurements on every frame!

thank you!

does zeiss smartlife sv asiana include these three frame parameters too? in one of your previous comments, you seem to say no but an optician i talked to said it does (?). also is there a big diff between sv asiana and individual? i understand Individual can take into account more personalized things about you like say you're an engineer spending many hours doing near/mid-distance repair. so if i don't have such special requirements is asiana sufficient or are there things besides this that Individual has that improves the visual clarity? (there doesn't seem to be anything online about the difference between these two types)

yes clearview is not bad! the thing is, peripheral distortion wise, my previous cheap OSS lenses were not that far off from the zeiss ones. i don't know if it means the kodak one is of significantly poorer quality (but then from the optician's brochure kodak and OSS/OSA seems to be under the same company now). my three specs have only slightly different lens width sizes (smallest 48mm, biggest 50mm), so i'm not sure if this affects the distortion somewhat other than the lens itself.

Nope, the Smartlife Single Vision or Single Vision Asiana using takes the default values of their Smartlife design (age plays a part in this), but the Individual is the customised one where they will use your individual parameters (pantoscopic angle, vertex distance and bow angle).

If you are above 30, actually I would recommend the Smartlife digital over the Smartlife single vision asiana/individual as it has the additional reading power for near tasks actually.

Kodak and OSS are under the same company, but they are two different brand of lenses. Could it be that the frame curvatures of both frames are different (e.g. one more straighter, one more curved)?

Both frames have similiar curvatures, one is only slightly more curved but not significantly so.

Thanks for your response, I am considering the smartlife digital individual lenses. Might you have a shop that I can potentially visit? Feel free to direct message me as I cannot seem to message anyone

The shamir lense really garbage.

Wiped with the same microfiber cloth.
One side at the inner side now full of scratches.

All on the inner side. Is the coating both sides or inner side?

Used exactly a year.

And it's not even scratches. Scratches would be in straight lines. It's in lines of spots. Obviously coating came off for some reason.

Should have bought hoya.
Someone recommended nulux and hilux duno what difference.

no difference la. all will have some extent of coating dropping issues sooner or later, even hoya or zeiss etc.

Not all coats are made the same.

Many opto told me hoya has the most resilient coating. Probably pentax too since they are sister brand and probably used the same coat. My cheap pentex did not come off and lasted the best with the coat is fully on after years of wearing. Coat coming off is easy to tell and should not be mixed up with scratches.

As for this shirmir, they acknowledged that it's a defect and replaced it one for one since it happens within a year.

Crizal is another brand that had an infamous reputation of coating coming off.

Next lens I will definitely go for hoya. JB is selling at half the price.

I said all are the same becos im using hoya lens and coating also came off. Used to be very good but recent year batches not so good. Coating came off like wat u said many spots after less than a year.

Thats why i said all are the same nowadays. Pay alot also same coating will come off. Sooner later. And to which extent only.

all made in same factory in thailand

Some lens companies have their labs in Thailand yes so that we can receive more customised (made to order, Rx) jobs in a week rather than 2 weeks, but most if not all of the lens companies are usually willing to do a 1-year warranty exchange if the coating gives way (e.g. coating peels, spots etc). In some very special cases, they may cover even past 1 year (but this is dependent on the shop’s relationship with the company and the company’s salesperson).

On a slightly different note, anyone knows of a good place to do eye screening?

My Zeiss Smartlife Pro Digital SV glasses are starting to get blur for near-field reading. I know I can get my eyes checked at the optician but wanted to do a more comprehensive eye screening as well.

Sent an appointment request to SNEC but received no reply. Slots at RP optometry clinic is impossible to get. I saw some eye screening packages at Ng Teng Fong Hospital, anyone tried that before?

Can try other polys. Did one at NP's.

Hi can someone recommend me a good optometrist that offers Zeiss progressive lenses?

Priority is on quality and expertise as i have a complicated condition and i need the glasses fitted very well. Money is not an issue as long as not overcharged since i can claim for this. Thanks!

Actually you don’t necessarily have to go to an eye clinic or hospital for this matter, you can go to any optical stores who has an Optometrist that provide retinal imaging services if you wish for a more comprehensive examination some of these places also have a slit lamp to check for cataracts and also a eye pressure machine to check for glaucoma etc. can call in to places to ask!

If your Zeiss digital lenses are starting to become blurry recently for near, it’s likely that you may need just to increase the reading power too.

So far there are only Optometry centres at NP and SP.

Thanks - popped by a store and indeed it was the reading power that needs to be increased. Jumped from 0.75 to 1.25.

Also switched from Mykita to Lindberg!

 

[threestageleastsquares]

I used to go to Mimeo for lenses but it seems like they closed earlier this year. Last message I got from them in January was that they would reopen in a few months, but it's been radio silence since. RIP.

What's a good place for lenses only local shops? To get Zeiss or Hoya or whatever.

 

[boringLife-]

I see taobao got shop selling frame + zeiss lenses with prescription for 80 sgd nia. The merchant say can scan qr code to verify authenticity and if I can prove it is fake will compensate me x4 the selling price.

Zeiss got so cheap 1? I can choose between 德国蔡司 非球面镜片 or 德国蔡司 防蓝光镜片

Welcome! Both brands are excellent, but I believe Lindberg is now more popular than Mykita in Singapore.
