    Bifocal sunglasses

    Several times on the ride back from Gillette I had a very uncomfortable experience riding eastbound mid-morning due to sunlight in my eyes
    Need to wear my glasses to read GPS or Map, and have been looking at some of the cheap sunglasses with what appears to be a small magnifying insert
    Any experience with these ?
    Thanks

    Hey Jim! Our neighbour (on the other side) in the Sherpa Village told Dave about stick-on bifocals. He picked up a set at Wal-Mart down in Gillette for about $8, and put them in his sunglasses. They worked very well, so we're going to look for a couple more sets up here. They should be available where the drug store reading glasses are found.

    I used these stick-ons for ten or more years, until I finally got to the point where I needed progressives, and had a pair of sunglasses made. You want to find Optx 20/20 (yes, that's the correct spelling) lenses. Go to your local drug store and try on regular reading glasses to determine the correct strength, then order them if you can't find them locally. I regularly lost one every few months, and got in the habit of using just one on my regular sunglasses. Worked fine for reading the instruments, and halved my replacement costs.

    You can trim the lenses with scissors to fit any size sunglass lens.

    Google "Optx 20/20" and you'll find lots of places to order them.

    I use the transtion / photo grey lenses and have for over 20 years total. I no longer worry about dark glasses at all.

    Tip O' the Day

    For all you eyeglass wearers, it can be very economical to have bike only eyeglasses made. Assuming (I love that word!) you have some old but serviceabe frames available, look in the phone book for your local optical laboratory. These are the folks your optometrist sends your glasses to. Obviously they don't advertise to the public, but call them and ask if they take walk in customers.
    I get bifocal lenses made for $28, tinted for $33. As someone above mentioned, I have a much smaller bifocal section made, usually about 10cm tall. That allows me to see instruments, tankbag, GPS in near vision, and distance for mirrors and all else without having to shift my head.

    What is with the reluctance to shift ones head? It ties in with the "choice" folks who claim that a helmet limits their vision significantly. I have my head on a swivel all of the time checking my surroundings, instruments, mirrors and even the scenery. I call it maintaining situational awareness as well as problem avoidance.

    I have prescription sunglasses that are multi-focal rather than bi-focal. The prescription changes smoothly as you move down the lens rather than the abrupt change you get from bi-focals. They're available almost anywhere that dispenses prescription glasses but they're not cheap; about $300 US.

    My wife uses bifocal sunglasses that she purchased, over the counter, at one of the US big box stores. She says that they are great!

    My experience is different from Charlie_K's. I tried riding with progressive lenses in my sunglasses, but found the change in focal length as I looked from left to right, or up and down, disturbing and disorienting. I went back to bifocal sunglasses which work very well for me. I had them ground so that the "near" segments at the bottom of the lenses are smaller than normal: they permit me to see the instruments clearly, but with my head in its normal alignment, everything above the instruments is seen through the "distance" upper part of the lens.

    Tri focal

    my sunglasses are progressive tri focal and I have never had a problem with them.

    The are very expensive $300.00, but worth it.

    All of my glasses are progressives.. They are all about who makes them and who gives the instructions to make the lenses .. I have taken lenses back to my optician 2 and 3 times because I've had problems with side to side ,out of focus and other distortion problems.. My optician will take the time as long as it takes to make sure the progressives are perfect.. He tells me there is never a reason that they shouldnt be right. It's all about how they are made, where the transitions are, the formula that's used and the bend and placement of the frames.

    Cool

    I had pefect vision till a few years ago. Experenced the same problem. It took me a while to find solutions that worked for both of my hobbies; riding and target shooting. I now use a pair of prescription eyeglasses with progressive transitions lenses or a pair of prescription sunglasses with progressive lenses for riding and driving (depending on the day). I use Champion Olympics for air pistol.

    Transition Lenses / Bi-focals - my 2 cents

    I use transition glass bifocals behind a clear face shield . They work great , day or night . I haven't used a tinted shield in a while , for fear of getting caught out dark and and also the hassle of bringing a second shield along.
