I’m looking for multifocal contact lenses that will fit my eyes. Can you help?
Question: I currently wear Acuvue2 contact lenses. D -4.0, BC 8.3, Dia 14.0. They are very comfortable and I have no trouble with them. Problem is, my eyes are changing and I now need multifocal/bifocal lenses. What brands would you recommend that are available in my prescription, base curve and diameter???
Answer: The base curve and diameter probably won’t be the same with multi focal lenses anyway.
They are often difficult to fit, and use.
The only way you can find out is by having your Dr. get trial lenses in a couple of different brands, and try them out.
Where can i buy multifocal contact lenses in Hong Kong?
Question: I live in Zhuhai and have not been able to find such lenses anywhere in GuangDong.
Answer: i searched it, most answers shows normally it’s not good for you eyes, not everybody fit it.
so i think common glasses is a good choice.
Who wears Multifocal lenses?
Question: In the past 12 months I have been prescribed 4 lots of lenses from 2 different Optometrists. I can’t see clearly when I look left or right (blurring)and my vision gives the feeling of a swimming motion, they are driving me crazy. After not getting any help from the optometrists (just sent off and told to get use to them) I phoned the Optometrists Association, the gentleman there told me about 20% of people can’t adapt to them. Has anyone else experienced this and what did you do. Thanks
Answer: MINE ARE LINE-LESS AND ARE CONSTANTLY CHANGING AS YOUR EYES GO UP AND DOWN ——–TOOK ME ABOUT 2 WEEKS TO GET USED TO THEM ——–WOULD NEVER GO BACK TO ANY SINGLE VISION AGAIN . —-YOU CAN NOT LOOK SIDEWAYS WITH THEM ——YOU LOOK STRAIGHT OUT THE FRONT AND TURN YOUR HEAD TO SEE IT —–WHEN YOU GET USED TO TURNING YOUR HEAD NOT ROLLING YOUR EYES YOU’LL HAVE IT MADE .
Multifocal Contact Lenses ????
Question: I currently am using lenses for my middle distance, and just wear glasses with them for real close work. I have just changed my job and now would like to switch to multifocal lenses. Does anyone know how they work?…I could never get on with Varifocal glasses, how does your brain know which part of the multifocal lense to look through? or doesnt it work like that?….are they expensive?….whats a good brand?…hope you can help. Thanks
Answer: Complex answer, I’m afraid.
There are numerous ways of providing multifocal vision in contact lenses.
Only one of them relies on you looking through different parts of the contact lens, and that’s almost obsolete.
(rigid lenses that sat on the bottom lid, and rode up relative to the eye on looking down, giving a different, reading power nearer the edge of the lens. Best for longsighted people whose lenses tended to ride low anyway.)
Cheapest route is monovision: correcting one eye for distance and one for reading.
This allows the correction of astigmatism with toric lenses, not generally available with other techniques, and doesn’t require special lenses.
When it works it works well, but only about a third of brains learn to swap eye dominance as required. (Some are too one eyed, and can only work one distance, and some are too two eyed and hate the disturbance to binocular vision)
The other multifocals, in a range of brands, present both distance and near images to each eye at the same time.
This works at all angles of view, which is the major plus over varifocal spectacles.
Basically when you look in the distance you see a clear distance image with a blurred near one superimposed, and the reverse for near. But it’s not quite perceived like that.
The extra flexibility is being stolen, or if you prefer borrowed, principally from contrast levels.
Blacks are not quite so black, whites are not quite so white.
In a good contrast environment that’s usually fine. The difference between black and white still allows crisp images at all distances. But in poor light the vision can be markedly compromised, since you needed all the contrast you could get. Night-time glare can also be a problem.
Different brands have slightly different ways of trying to minimise this, and some are better with bigger/smaller pupils, but the effect is inherent.
The good brand is the one that works on you!
