Today I'm not much smarter but I'm a lot more experienced, and I appreciate the comments now more than ever before.
I've had soft 30-day multifocal contact lenses for over six months, and the habits I've developed are different than I anticipated. Before presbyopia I had nearly flawless vision, and I'm told that I'm [-]unreasonable[/-] very particular about finding the right lenses to get back to that state.
First, the little buggers are tougher to put in and take out than I expected. It was a couple months of daily practice before I got proficient. The method I learned at the optometrist was too difficult for my [-]Neanderthal forehead[/-] deep-set eyes and I finally found a better way on another contact-lens website. Then it took me a few more weeks to realize that, unlike hard lenses, soft lenses are never supposed to feel painful. I'd frequently roll under an edge as I was inserting the lens, feel the twinge in my eye, not realize that it was a problem, and just live with it. One day the lens slid off my eyeball, rolled up like a grain of rice, and actually trapped itself in my lower lid against my eyeball. I didn't find it until the next morning. But I eventually figured all of that out and it's fine now.
Second, multifocal lenses are an imperfect compromise between distance vision and reading vision. My left eye is 20/15 without the lens, but the lens has a "plastic wrap" feel that blurs my distance vision. I could no longer clearly see the mountain range 10 miles away, admire a nice [-]bikini[/-] longboard from 100 feet, read a license plate from 50 feet, or even pick out smaller street signs before I got to the intersection. I tried a couple different prescriptions but there doesn't seem to be a solution to this acuity problem for multifocal lenses. When I had a prescription that could see "OK" for distance, I'd have trouble reading fine print. If I could read fine print then anything outside 40 feet would always be blurry.
Third, you can surf with soft contacts. Splashes are no problem and soft lenses will even stay on your eyes underwater for a few seconds. However it's a pain and I was always checking my eyes to make sure the lenses were still there. It's not much easier to remove/insert them in the parking lot, either, so I'd end up leaving them at the house.
Fourth, they were dry. I'd wake up from a nap with the lens literally stuck to my eyeball and have to wait for my tears to get going or squirt in solution. After 8-10 hours I'd generally be done for the day, and I never developed the stamina to go longer.
So this month I went back to the optometrist. We decided to ditch the Bausch&Lomb PureVision 30-day multifocals for an Acuvue Oasys 15-day monovision lens. No multifocals-- I just wear a 2.00 reading lens in my right eye and I don't wear anything in my left eye.
My left eye has always been very dominant and now I have my distance vision again. I can read street signs & license plates and see everything I want without the plastic-wrap effect. My brain hardly ever uses my right eye so I have to "force" the switch to reading vision. I can handle the computer monitor for a couple hours before my right eye gets tired. I can read for 20-30 minutes before I get tired, but when I add a pair of reading glasses then I can go all day. I’m told that this will get better as my brain learns to make the switch.
But already the nicest thing about having a reading-vision lens in my right eye is that I can immediately switch back & forth between distance & reading vision with no problems-- I can walk around the grocery store, see what I want at the end of the aisle, and read the fine print at the label all without having to squint or back off. I'm almost never fumbling for a pair of reading glasses.
The 15-day lens is a lot "wetter"-- no dryness or stuck eyeballs. It's also tinted slightly blue (instead of the perfectly clear multifocals) so I can actually see it in the lens case. It's no easier to insert/remove and I still wouldn't wear it surfing, but it's a lot less fuss to handle one blue lens in the parking lot.
In my case, multifocal lenses were
a cure but not
the cure. I didn't really pick up on monovision from reading the other posts, and I'll give these lenses another six months, but I'm surprised to learn that I already strongly prefer monovision over multifocals. (I'm never going back to hard lenses.) If I was confident that my presbyopia wouldn't get even worse, or if materials science developed a really really flexible artificial lens (maybe Restor already is), then I'd immediately have them LASIK my right eye or stick in an implant. If my lifestyle leads to cataracts then I'll choose to come out of the surgery with monovision.
The reality is that I take out the monovision lens every night and still put on my reading glasses every morning. I don't put in the lens until I'm going out, and if I'm staying around the house all day then I might never put in the lens at all. But being able to simultaneously read street signs and grocery-store labels is well worth the effort.
I'm a lot less grumpy about presbyopia than I was a year ago…
