Varifocal contact lenses

[RogerS]

Just wondered whether anyone had used these and if so how good were they? I'm right at one end of the long-sight correction (10 diopters for short sight) which is fine but it's close up work. I do wear glasses over the top to give me better near sight focus but bit of a *** to keep taking them on/off and remembering where I put them.

I guess I'm wondering just how noticeable is the focus change ?

hi rogers
I have worn them for several years now they are hard to get used to but I would say go to a very good optician ,
I had a bad time with the first place I got them from but now go to a very good optician and have not had any problems ,I was told there are different widths I got the middle ones but wish I had payed a bit more and got top of the range ,one thing I would do is make when you get them ask if you can't get on with them will they change them as a back up just in case you don't like them, some people don't like them at all.
they tell you to look with your nose and it is true when you wear them if you look to the right or left you can see as you go to the edge of the lens it goes slightly out of focus then turn your head and it will go into focus.
like I said my advice go to a good optician.

I've had them and found them to be far better than the ones I have now (the split type) you can choose the area that magnifies (at the bottom of the lens) with the split ones, I'm 'always seeing / awear of' that you can see the 'split line' I also agree with Pip, they take some getting used to, and go to a good optician. Down side there not cheap.

Are we talking about varifocal contact lenses as the thread is labelled or glasses?

I wouldn't have thought varifocal lenses would work. Never heard of them. As for varifocal glasses, you can keep em, couldn't get on with them at all, but the wife loves hers. I have bi focals now for telly and lappy, with the split lense, great until you want to see something close up above your head. I tend to wear over the counter readers for work as most stuff is close up and they get destroyed by dust & grime. I stepped off a kitchen worktop just before Christmas looking down through them and missed the step ladder completely. Torn knee ligament and much wailing and gnashing of teeth.

****** glasses :evil: ****** old age :evil: :evil:

I'd don't use contact lenses but do have varifocal glasses. If contact lens are anything like lenses go for the best quality ones you can. The first set of varifocals I got I couldn't get on with. I did some research to find that they come 'off the shelf' and altered to suit the individual so it depends on the manufacturer on the width of field and the rate of graduation. I ended up getting the most expensive but don't regret it. By the way the misses tried varifocal contact lenses and couldn't get on with them.

Don't know which optician you use but I'd highly recommend D&A (now in Boots) in Worcester. I've had excellent service from them but more importantly great advice.

Mark, how on earth can varifocal lenses work, surely they move with your eye?? :shock:

I tried some recently. Apparently they have annular rings of different focal length so it depends on your pupil dilation which ring you see through. Ingenious. If I understood what the optician said correctly.

I could read in daylight but not indoors where the light was less. I now use a normal contact lens with ready readers over the top when needed.

I tried them but could not get on with them but use one for reading in one eye and one for distance in another.
Again they take a bit of getting used to but I can now read the speedo whilst seeing the road ahead.
The varifocal ones have rings of various strengths whilst the ones I use are of the same uniform strength.
Most opticians will let you try them out for a trial period free of charge.

Intriguing. I thought that the reason why accommodation of the eye was likely to decrease as one got older...due to reduced elasticity in the eyeball meaning the muscles of the eye couldn't alter the focal length enough to focus on close objects... But different people have different elasticity, I'd guess, which would mean that the eye lens 'radius' for any given focal length is going to be different for each person...maybe? So do you have to move your eyes up and down until you get things in focus? What is the focussed field of view?

Mmmmm...might try and blag some from my optician.

My Opticians gave me some to try for a week and then another week with the two different ones - they must cost peanuts to them?

However I was "upgrading" from "normal" types so had been used to wearing lenses for many years.
Lenses do take a bit of getting used to anyway and you have to build up the hours. I use daily throwaways so no cleaning solutions required.
