I have been involved in contact lens related business & visual health since year 2005. I myself started wearing contact lens since early 2000.
this thread is purely for all members to share or ask information about contact lens & related product, as requested by many of my regular and new customers here in lowyat.net. please do not flood my pm inbox with questions as i prefer to answer them here in order to prevent repeating myself answering same question from different members. thank you very much for all your consideration and support all this while. Added on March 21, 2009, 1:03 pmthe most commonly asked question in my pm was 'WHATS THE DIFFERENCE BETWEEN O2 OPTIX & AIR OPTIX, WHICH IS BETTER?" i usually directed them to another member's thread in kopitiam, but i would summarized it here. both o2 optix & air optix are manufactured by ciba vision. AIR OPTIX has the same material but with copolymer 845 to improve surface properties, to mousse foams and form clear, smooth-feeling, non-tacky films on lens surface. air optix is aspheric design while o2 is spherical design. aspheric lens offer thinner periphery thus less lens edge sensation, so better comfort. some said it offers better visual acuity but i personally did not feel any difference compared to spherical lens. i tried both before, even with 1 piece o2 optix on 1 eye and air optix on another eye but honestly i cant feel any difference in terms of vision and comfort.

i got a few questions about contacts:
i don't know whether it is a myth or fact, but can u explain whether if you wear contact lenses, your vision's short sightedness will increase or stay the same compared to wearing glasses? 2nd, how long does 2 boxes (6 disposable lens) last you ? my shortsightedness is just 0.75 and 1.00, astigmatism is just 0.75 for both eyes.. thinking of going for contacts since cant see at night properly.. |

My prescription's about -7.00 for both eyes and I have astig (can't remember what cylinder). The clinic I visit prescribes me RGPs (the last ones I got were Menicon-Z) citing better ocular health. What do you think?

What do you think? i definitely agree with them, Menicon-Z is 1 of the best RGPs in market, same par with it will be Boston XO. both of them have the highest oxygen permeability thru the lens to cornea, provide superior visual correction and show excellent performance against astigmatism. both contain UV absorber which can help prevent cataract. benefits of long term corneal health, vision, comfort and wettability in order to reduce the burden to the cornea. just 1 disadvantage, they r more fragile than other type of RGPs. thanks |

What do you mean by fragile? As in, they break more easily, bend out of shape more easily, scratch more easily, or?

As in, they break more easily, bend out of shape more easily, scratch more easily, or? they break more easily than the other RGPs. bend of out shape (flexure) is still not prominent as they r quite flexible and usually return to original shape pretty well. scratch resistance wise they r as good or better than the other RGPs. QUOTE(kenn723 @ Mar 22 2009, 02:10 PM) if 1 box has 6 pieces, then 2 boxes u will have 12 pieces, as u got 2 eyes that wear lens, so with the 12 pieces u will be able to use them for 6 months then. thanks |

How long it takes for eyes to get use to contact lense. Will my eye turn red o sumtin after using it during the beginning? if u are using bausch & lomb contact lens, then its good coz all their lens store using renu multiplus in the plastic seal. but it doesnt really matter coz nowadays contact lens solution are pretty much very similar. if u using silicone hydrogel lens, then better use optifree or solo care aqua. what is ur eye sensitive to? silicone hydrogel lens is suitable for all sensitive, even allergic eyes. u will have foreign body sensation when u 1st wear the lens, mild redness but should not last for more than an hour. QUOTE(soon90 @ Mar 23 2009, 12:06 PM) Jialat is really a good seller. I forgot to tell him that i have received the contact lens and after a few days, he sms to check if I have received it. Highly recommend to all of you! hi soon, thanks for the feedback. keep in touch. QUOTE(meme8 @ Mar 23 2009, 02:48 PM) for yearly softlens, u should use protein removal tablet at least once a week. daily cleaner solution will be great too. if yearly RGP lens, u can send it to optical shop for 'recycling' once a few months. thanks |

QUOTE(wKkaY @ Mar 23 2009, 05:32 PM) Thanks for the responses so far. Another one, when would you recommend a patient RGPs over soft lenses? i strongly recommend RGP rather than softlens especially for those with corneal astigmatism. also for teenagers in order to slow the progression of myopia (nearsightedness). patients with corneal disease, warpage, or irregularity can benefit only from GP contact lenses to smooth out the front surface of the eye for appropriate refraction of light. Examples include: keratoconus, corneal transplants, refractive surgery, corneal trauma, and warpage. Visual quality can be improved dramatically with GP contact lenses, compared with soft lenses or spectacles, and many patients depend on them to function visually. hope the above helps. thanks |

Thanks. I don't think I have any of those other conditions, but I do have corneal astig (tested with a corneal topo).

RGP correct corneal astigmatism easily by masking the oblong cornea and providing a surface that optically performs like a spherical cornea. thanks |

Just wondering, I know it's not a healthy practice. I tend to wear my contacts when I feel like it, as in when I'm going somewhere that's nice. Technically I wear my contacts only like one or twice a week. The rest I just use my glasses. And I find it a waste to throw it after one month opening it. So I tend to still use it even after a month considering I rarely use it. I know you would say that it is not advisable, but what can happen if say I continue using it for at least 3 months? Thanks!

I'd really rather have you guys inquiring about Jialat's contacts lenses via PM. This is actually touching the borders of breaking the rules in H&F. We're very anti-sales.
Thank you. |
