I'm short sighted. Before my games, I change from glasses to contact lenses (one day Acuvue).

Err, today, I accidently brought out two left eye lenses. Hmm, so what to do? Going back home is too far away. So I just put one of the lenses in my right eye as well. Fortunately the power is not too different and the curvature fits my right eye.

Hey, tonight I win all my games:D with the "two left eyes"....:p

I do the same thing, but I have an added problem. I normally wear bi-focal glasses. So when I put my contacts in, l cannot focus close. The nearest focus is over 3 feet! I wonder if anyone else has this same problem and what you do about it?

:(

Use the force Cheung...use the force

I never got the hang of doing sports in contacts so I went back to specs for everything.

Nice left eye experiment Cheung ;)

Last friday i also had an left eye contact lens experiment ... i even didn't have to visit an optician for that !!

Well the lens in this case was the left glass of my glasses thingy. Court situation in mixed doubles with me standing at the net and not protecting my face with the racket was ideal for this experiment.
The willing opponent hit as hard as she could... btw her standing not too far from the other side of the net sure helped to have optimal impact speed...
And then there was the clash... between the shuttle and my left glass.
The impact was hard enough ... so the glass, made of some plastic type material, decided to leave the frame and try if it had a good fit on my left eye.
Personally, having done this experiment, i think the glass is too large to have a good fit as a contact lens. :rolleyes:

A problem arised while refitting the glass in the frame : i had no idea which side was up or down... :confused:
Eye weakness being -5 combined with a cylinder of -1 making a total of -6, i remembered that the cilinder only covered a certain area. Well, since the refit, we
still won the game so probably i did it right or it didn't matter anymway.
:cool:

I just had laser surgery to fix mine....it's so much easier not having to p#!$ around with lenses and so on

T

Yong..............that's....erm.......very scientific:p :p :p

Laser surgery to the eye for short sightedness has a 0.5% complication rate. That's 1 in 200 which is too high for me. I'd also rather not mess around with glasses/contact lenses. If, after having surgery my eyes had a complication, how to continue playing badminton??

See.... Nothing is 100% better over another.

Here's at least one reason, regular glasses are still good. No way u can get 2 left eye glass (unless u never check when picking up)... :D

I just came back to HK from UK. I read from UK Newspaper that there's a big lawsuit against laser equipment provider because there's defect on the laser machine.

A lot of poor short sighted guys were operated with inaccurate laser machine!!!

If I remember well, it's Boot that get into trouble.

By the way, if you live in HK and have some eyes problems, the best place to check your eyes is "HK Polytechnic University"(tel 2766-5226). They charge only HK$350-500. But they will use PhD in Eye(Optician) to do that. The whole process will take ONE Hour. If you check your eyes somewhere, it takes 15-25 Min. They also have the latest machine.

When I was there checking, many of the eyes specialists were wearing glasses and I asked them why they had poster for laser but so many staff are wearing glasses. I was told that they couldn't estimate the after-laser-effect for the next 20 years.

yes, i notice this discrepancy when laser eye surgery first came out commercially... 15-17 years ago?? Where i live, there is a world reowned eye surgeon (dont want to name him)/ He get refereral from other eye surgeons for special operations, and he now has many many high end laser surgery offices under him. I saw him several times on tv interview over these years. When ask why he hasnt had laser eye surgery, he said it's not suitable for him :rolleyes:

Dr. XXXXX is internationally known for his contributions to the field of ophthalmology, particularly in cataract surgery and in the rapidly developing field of refractive surgery. He has been appointed to the Scientific Advisory Board of the American Society of Cataract and Refractive Surgery and, in 1999, was named by that society as one of the top 25 ophthalmologists of the 20th century. He holds faculty appointments at the University of YYYYY and the University of California, San Francisco, and has been associate clinical professor in ophthalmology at LLU’s School of Medicine for the past decade.

Maybe he could not perform the surgery on himself :confused: :D

Cheung, try again next session with 2 'right' eyes and compare the results. If any of these are better than wearing 'right and left' consider playing the tournaments with either 'lefts' or 'rights' (whickever yields better results) only. :D

this so reminds me of the rock leg pain experiment. would Chueng actually go to the trouble and pain (and perhaps risk optical health?) to find out that answer? Chueng could you facilitate us with your answer? thanks what ever the outcome.


sorry if i have gone OT. :o

cheers :)

I have been very careful not to do the same thing again!

Most opthalmologists will not undergo laser surgery as their operative work is like microsurgery. The risk against benefit is too great.

I say 'most' because two HK opthalmologists did take up the challenge and operate on each other.

Long term effects of surgery are not known - that is another reason for me not to undergo surgery. I can survive OK with shortsightedness. What if I had the surgery and cannot play badminton as a result? :crying:

I don't know how old and how "short-sighted" you are.

The good news is: when someone get some "short-sighted" when young, the "short-sightedness" will be balanced by the "old flower" develope around 40 years old. That guy will get less short-sighted or become non-short-sighted.
Good luck.

HK Poly U is very very good on eyes checking. Must try whoever got any eye problems.

you mean that person will see 20/20 for a few days as the eyes go from near to far sightedness?

Actually, we get old we will develop Presbyopia(pronounce as "old flower" in Chinese), if one gets a little "short-sighted" when young, the short-sightedness will be completely or partially balanced out by the Presbyopia.

As a result, some short-sighted individuals will get less "short-sighted" or even don't need to wear glass.

Isn't it good?

i thought the old flower thing had to do with old tired 'eye muscles' getting 'stiff' and facing difficulty crontracting and expanding. so if he does get old flower wont the dude still need glasses to read?

please enlighten me. thanks

from www.allaboutvision.com

Age-related changes occur within the proteins in the lens, making the lens harder and less elastic with the years. Age-related changes also take place in the muscle fibers surrounding the lens. With less elasticity, the eye has a harder time focusing up close. Other, less popular theories exist as well.

thanks dude. so its safe to say i'll be using reading glasses when my time comes. :D

I wish that were the case, then I would have had 20/20 vision by now. Unfortunately what happens is when you are "short-sighted, you cannot focus on distant objects. When the "low far" sets in, you will also lose the ability to focus on near objects (eg. reading). So the 2 problems are additive and do not cancel out each other. :mad:

You are right!!! Some unluck person have both. The glasses are extremely expensive for "low far" and short-sighted. I wish that were the case, then I would have had 20/20 vision by now.

That's the reason why I don't want to go through Laser Surgery.
I've been wearing contact lenses for years, lately I wear the daily
wear contact (Focus Dailies) and very happy with them especially
when I travel or go to tournament, they're so convenient. To prevent
from having 2 "left eyes, right eyes" problem or even lose 1 during play
(which hasn't happened to me yet) I always have a couple of extra
pairs with me.
