    Default Purevision 2 HD for Astigmatism, do they stay put?

    Hi Guys,

    First post! Google's taken me to this fine site whenever i've researched a new lens. Really hoping you guys would be able to help me out with a question i've got

    So bit of background since moving to a Toric lens, i've tried Coopervision Biofinity toric (comfortable but not very sharp vision), J&J Acuvue Oasys toric (Really comfy, but vision tailed off and the halo was a touch odd).... which has then taken me down the Bausch & Lomb route. For me and my eyes B&L give the crispest vision.

    Here's my B&L dilemma, I tried B&L Purevision Toric and they were ace, crisp, ok comfort, could sleep in them for a few days (i used to get a whole month out of the biofinity's, though the vision was a bit pants). However, on my work days i get the train, and like all the minions travelling into town i have my head down reading the paper, driod, etc. The Purevision Toric's really didn't like it and would move off centre and require many blinks to correct. So it made me look like a little be of odd ball, blinking away on a packed train looking like i'm fighting the tears.

    So I now wear the Soflens 66, they have the ace crisp vision, they are comfy to wear too and they do stay put. But I miss though the ability to sleep in the lenses from time to time, even a 30min nap really messes these lenses up and it's just an ache to take them out and then put them back in.

    Would anyone know if the new Purevision 2 HD for Astigmatism stay put when you look down for a long period of time?

    Is it a size thing?

    PureVision 2 HD Astigmatism
    Dia 14mm
    Radius 8.6mm

    PureVision Toric
    Dia 14mm
    Radius 8.4mm

    Soflens 66/Toric
    Dia 14.5mm
    Radius 8.5mm

    Many thanks,
    Gi

    Hi grboorman. Welcome to Lens 101. I appreciate your interesting way with words. I don't think I've ever heard contact lenses being described as "a bit pants" before.

    Without looking at your eyes, and without being a eye doctor even if I could see your eyes, I had to use my only superpower--Extreme Internet Searching--to find a clue about your complaint. The best answer I found was that the base curve on your lenses might be a bit too big. If the base curve is too big, then that means that your lenses are too flat, and might slide around.
    Let your eye doctor know that your lenses don't stay put and hopefully you can get re-fitted with something that's more your size.

    Thanks

    Are Purevision more curved than the Soflens?

    Unfortunately I only use my eye doctor for eye health, as they have a limited range of toric lens (re-branded Coopervision), the somewhat robotic approach to service lead me to source my own lenses. On the plus, the internet has allowed me to try a plethora of lens in a relatively short period of time.

    Don't you have to have a prescription from your doctor to buy lenses? Do you live outside the United States?

    As for your "more curved" question, Purevision 2HD for Astigmatism has a base curve of 8.9 and SofLens 66 Toric contact lenses have a base curve of 8.5. The lower the base curve number, the more curved the lenses are, so you might say that SofLens 66 Toric lenses are "more curved."

    Hi Zoey,

    Yes I live in the UK, I don't know how it differs from the US. We don't have to have a prescription to purchase lenses, but generally they prefer you to have had an eye test done in the last two years.

    To be fair until a year ago I was on a pay monthly all inclusive scheme. So i don't know how purchasing from the internet will pan out in the long run. However I was on that scheme for 8 years, so as you can imagine i was somewhat disappointed to find that they wouldn't let me try J&J, Dailies or B&L without a substantial extra charge...

    So I guess that the PureVision 2's differ little from the PureVision 1's, i would be right in expecting the same kind of movement issues (for my eye).

    Thanks,
    Gi

    Well, I have been wearing them for a little over a month at this point. My answer to your question would be a yes, they do stay put, even when looking down or reading.

    Once in a while but not often I will notice that I have to blink a few extra times to stabilize the lens. However, it is very seldom and once the lens centers it stays where it is supposed to be.

    I wear a Purevision 2 Toric in my left eye a regular Purevision 2 in my right eye and ride all around LA on a motorcycle without any complaints at all. Simply put: these lenses kick ass, especially at night when it matters most on a bike. I wasn't so confident anymore in my Air Optix Aquas once I started riding a bike again. Those lenses couldn't take the "excitement" and the toric would de-stabilize constantly which I found both dangerous and frustrating.

    So, I asked my doc about the Purevision 2 (and regular original purevision) lenses and she Recommended I try out the 2's and fell in love with them. I understand that mileage may vary with contacts but I do want to make it a point to express my gratitude for this product because I was hoping I wasn't going to have to wear glasses while riding my motorcycle and the unanticipated amazing night performance sold them regardless of cost. The amazing thing is I paid LESS for a year's supply of these over my old Air Optix Aqua which was an added bonus.

    Sorry to ramble on but I hope I answered the question: yes, these lenses stay stable and they are not a problem when looking down which I do by looking straight down at the instrument panel all the time without any shift in the lens' proper location on my cornea and this is with a PV2 Astigmatism lens in my left eye.

    Thank you for being the voice of an experienced Purevision 2 user. I hope you'll keep answering more questions. Some members have been waiting a long time for an answer of some kind.

    My pleasure, Petra as I love to help out where I can and I'd be glad to keep doing so as this forum has helped me greatly in the past to educate myself and to make informed decisions regarding my own lenses, etc..

    I did notice that there are a lot of really GOOD questions that have been asked just kind of sitting out there unanswered. When I see one that I clearly know the answer to or think my input may be of any use I'd be glad to chime in.

    Have a great day and take care.

    Thanks linkon99 just what I want to hear, really hoping these come down in price soon. Here in the UK I'm looking at about 90 for 3 months supply... compared to 30 for the Soflens 66... hopefully by my next order they will be cheaper

    hi

    i am in uk also and have done exactly what you have, i have tried my own trials, cost a bit but i will get a lense which suits me, i am settled at the mo on a biofinity toric for my right, but am told that i could get away with a non toric, but i want to get my left eye, .25 mild astig, sorted and i have ordered a box of purevision 2, they are supposed to cure mild asig.
    i was with asda but they had limited selection, so went to specsavers, who offered me a trial of their re branded lenses, i am sure they are not the same, they say the are but i never seem to get on with there re branded lenses. So i asked for a trial of oasys, and told him i would get them from the internet rather than the scheme, to which he was not happy, so i never got to try them

    heres the thing...all the lenses you have tried are super stable toric lenses.....another lens to try is cibavision air optix aqua astigmatism....a super stable high dk lens....however fhey need to be fitted because all manufacfurers toric lenses fit differently.Based on how they orientate the corrective axis may be different.

    Just put in an order for the HD2 Astigmatism, they're showing the base curve as 8.9 which i think is the biggest base curve I've tried. However they've come down to 50 for 3 months so in my mind worth having ago... it would be really great to get back to waking up and not having to put lenses in.

    If this fails then i probably will start going through the CIBA Vision range, as i'm still a little risk adverse when it comes to LASIK, i blame youtube for that!

    Last thing, what's a 'dk' lense?

    dk/t refers to the oxygen permeability of the lens (usually measured at a -3.00 power). ANd refers to the area in the center of the lens.

    As for the original poster...toric lenses orientate differently on everyone and is largely based on the curvature of your cornea and how high your astigmatism needs to be corrected.

    Heres the thing...soft contact lens disposables ONLY come in a limited range and fit like shoe sizes. If you need a more custom fit your ecp may recommend rgp lenses which aare totally custom designed for your eyes.
