Hi, is spectalcles hut, optical 88 or nanyang optical gd ? Cos think its time to change my specs, last time check my eye 5 years back left eye -7.00, right -7.5, astig quite high, i intend to get a frameless spec , any expert know the average price here? Cos i dont want to get chop, please enligthen me and thanks a million

 

[jonathanckh]

o: which model you got? why so ex

I think its reflex 3201. The half rim one. I think i kena chop carrot though. Maybe because i first time prescribing glasses so dont know anything. The salesperson kept pushing me to buy the crizal lens although i wanted carl zeiss. He said that the crizal 1.6 is 280 and the carl zeiss also 280. Then i blur blur go say crizal lor. Nvm, pay already cannot do anything abt it.

 

[Citiguy]

is exaggerate scenario but he has the idea right.


This is the path society seems like headding.. what can u do about it? =/

Lan Lan follow the crowd lor..

Agree, xiaokaka.

BTW, what is AR coating? TIA for replies.

i will recommend nanyang optical as being the better choice. One of the oldest optical chain ard. Its Chairman, Yang Wah Kiang, has spent much of his life working with optical technology and in eyewear manufacture and design, and the Urband Origami is a demonstration of his hands-on approach to applying existing technical know-how and technology to the design of innovative eyewear. They strive to be one of the best international eyewear design and R&D companies in the world. I particularly like their in-house brands which are quite different & unique from other brands out there in the market. They are all light, comfortable, innovatively designed, value-for-money.

As for spectacles hut & optical 88, they are the "newer" optical chains. I dont see any speciality in their products. Their prices not that cheap as well. So, you may kena chopped in these places.

As for your prescription & astig high, i dont think you should get rimless frames at all, becos it will be visibly thick even if you use the highest index lenses. Furthermore, the weight of the lens will bore down on your frame at the front, so you will feel heavy on your nose & the specs will not feel so balancely-fitted. And frameless spec also has the risk of your axis running adrift, and with your high astig, even axis 1 degree off you will see blurred. Just like for me, my left eye astig is 325 degrees. So any one degree of axis off my whole vision is blurred. So i always need to remind the optician to get my axis perfectly correct while edging the lens, and hope that the lab will make it right. I will choose reputable lens brand so that to ensure better quality, eg hoya.

I strongly recommend you to choose the double aspherical design instead of the single aspherical design of your lens. Believe me, it will make a lot difference to your vision.

Agree, xiaokaka.

BTW, what is AR coating? TIA for replies.

AR coating is Anti-Reflection coating.

Anti-reflective coating helps to minimise the problems with transmission of light and reflection which causes glare to your eyes.

Unless you're talking about sunglasses, the more usable light that passes through a lens, the better.
A standard plastic lens transmits about 92 percent of incoming light to your eyes. As lens density increases, light transmission falls. In a 1.74 high-index lens, about 86 percent of incoming light passes through. This difference may be negligible in full-light conditions, but it can become more noticeable in dim light.

What happens to all that light that is not transmitted through the lens? Much of it bounces, or reflects, off the surface of the lens. Unwanted reflections can come off both the front and back surfaces. Another word for this reflected light is glare. The denser the lens material, the more glare it produces.

That is why u need to have AR coating to feel more comfortable and lessens the glare and to see better

IMHO, -750 get 1.74 looks better.

1.67 can do the job no doubt. Clarity higher, light transmission higher, abbe value higher is correct.

so now depends on the wearer looking for clarity or looks.


Best clarity lenses in the market is Glass 1.5 Uncoat.

chanzhf has already said that he is a poor soul. And for your info, 1.74 lenses at his power is much more expensive than 1.67 lenses. So the little bit of difference in thickness really does not justify him getting 1.74 lenses. And really, 1mm does not make much difference since the lens will already be thick enough. 1.67 or 1.74 both wont look nice, especially on frames that cant cover up much of the thickness. So i feel that for cases like chanzhf and myself, 1.67 is more than good enough. Asethetic wise. Or clarity wise. Or money value wise. 1.67 is teh best choice. For now.

Oh, so glass is the clearest, but wont 1.5 be very thick & heavy?

Stark is very High end unique designs.. cheapest is around $800+ i think.. Not many places carry it tho.. grats to ur hoot.

starck is super high-end, this guy must be a loaded uncle. But the frame not comfortable. I tried before.

 

[Seannie]

If nylon's fibre breaking off, can change nylon string.

U post hi-res shot see if any1 else can comment.

the nylon didnt break off, its just frilling a bit, cant really see unless look very close-up. Y i notice it? Becos i could touch the roughness on that particular spot on the nylon, so i went to take closer look under the light and saw that a tiny bit is hanging out. Just like your jeans or shirt u noe, the ends coming out liketat, just that its very tiny.

I wonder how the nylon can become like this. Is nylon material v fragile & v susceptible to abrasion & damages?

hi all, can recommend what shops carry japanese brand frames ? i find them quite professional yet stylish looking. pls share, thanks.

 

[Seannie]

Lan Lan follow the crowd lor..

anyway dont worry la. nowadays, banks are offering you better & better credit cards that allow you to stretch & pay in instalments. Buy first slowly pay.

 

[Seannie]

Thanks for your suggestion. i really had no idea the difference in thickness between 1.74 and 1.67 at my power. It is after all, a novelty, i mean, i might go for rimless and better lens in the future and this might be a precursor to getting better quality lens when i can next afford it.

As for eyewear and vanity, well, i think that sometimes spectacle frames do make a fashion statement and difference. I do save the contact lens for occasions; To each his/her own.

Since we are on the topic of 1.74 lenses, maybe you could shed some advice on a poor soul like me, if my myopia of 750 do not require 1.74 lenses, when should a person actually get 1.74 lenses, taking all other current lens technologies and options into consideration? Thanks

High-density materials can create a lens that is up to 40 percent thinner than a traditional lens. The key words in that statement are "up to." For people with higher prescriptions, the cosmetic and comfort advantages of these lenses often far outweigh the related performance and cost issues. On the other hand, those with lower prescriptions (under plus or minus two diopters) may find that the change in the thickness of their lenses is minimal.

Solutions
Many of the problems that are inherent in high-density lenses can be countered with additional technology. Problems with lens blur often can be reduced by requesting an aspheric lens design, in which the lens curvature gradually flattens toward the perimeter of the lens. Problems with transmission and reflection can be minimized by adding an anti-reflective coating.

i will recommend nanyang optical as being the better choice. One of the oldest optical chain ard. Its Chairman, Yang Wah Kiang, has spent much of his life working with optical technology and in eyewear manufacture and design, and the Urband Origami is a demonstration of his hands-on approach to applying existing technical know-how and technology to the design of innovative eyewear.

Hmm, i think i will go nanyang optical then, thanks for ur advice

 

[shadowclause]

Hello poly student here planning to make a pair of specs pretty soon.
Would like to ask a few questions.

1) What type of lens coating is the best? Hoya sft? Zeiss? Essilor? Budget-wise hoya is the best right?

2) Thicker lens is perfectly fine for wayfarer style of frame right?

3) Is it advisable to make specs at school (poly)? Is the 15% discount they offer worth it or is it much better to go to kwong shin to make?

TIA!!

Hi, is spectalcles hut, optical 88 or nanyang optical gd ? Cos think its time to change my specs, last time check my eye 5 years back left eye -7.00, right -7.5, astig quite high, i intend to get a frameless spec , any expert know the average price here? Cos i dont want to get chop, please enligthen me and thanks a million

Your prescription so high, frameless not so nice...

If u really want, get 1.67 Bi-Asp and not 1.74 for the lenses imo..

1.67 tensile strength is much higher than 1.74. Bi-Asp design may be very close to 1.74 thickness but cost may be higher.


Frame cost can be between $20 all the way to $15k..

Depends on what kind of pricing u willing to pay for.. then we can decide some decent brands to fit into ur budget. Brands so many in the world, cannot say finish 1..

Nanyang did not work out well for me. I made a pair of reading glasses at the Compass Pt outlet that were really off! I can't use it to read. They are now suitable for intermediate distance. They told me that I would eventually get use to it. But it mucked up my progressive lenses too. I paid 360 for those glasses.

Bah! I just went to have it done properly at the Eye Place. No more Nanyang for me.

I think its reflex 3201. The half rim one. I think i kena chop carrot though. Maybe because i first time prescribing glasses so dont know anything.

Nvm, pay already cannot do anything abt it.

Crizal 1.6 advance cost $160.
Crizal 1.67 advance cost $240

Carl Zeiss 1.6 cost $240.
Carl Zeiss 1.67 cost $320

Prices are Recommended Retail Prices in SG by these 2 companies.

among this 2 brand, Carl Zeiss is considered as Premium brand. If same price, Zeiss is a better option.

Either way, u can try go back shop and ask to see their RRP for Crizal and Zeiss to make sure it's really $280. RRP by these companies often comes in Laminated and relativly high quality printing with their own Brand and Logo proudly printed on it or in a delicated Folder. Not just low quality coloured printed A4 paper.

 

[xiaokaka]

Agree, xiaokaka.

AR = Anti-Reflection (Multi-Coating)

Does not mean it WILL come with Scratch resistance OR UV400
