Hi, I am in my mid fifties and am struggling with not being able to see my cycle computer. I have been wearing "drug store " reading glasses 2.50 for ten years. My eyes are fine otherwise.
I have tried the FSA Control Center which is allows you to get the computer a few inches closer but not close enough. I ride with the reading glasses hanging around my neck and put them on with one hand when I want to see the computer which is not the safest thing to do. I am now searching for a computer that has unusually large type and am finding this difficult. Does anyone have this problem? any comments would be appreciated

Simply go to your local hardware or DYI store and get some construction safety glasses with 2.50 bifocals. They look like sun glasses and will protect your eyes and you will be able to read from the bottom half. They come in clear, yellow or dark grey.

I like the other poster's suggestion.
I wear prescription bi-focals all the time. Several years ago I cheaped out buying sun glasses because I couldn't imagine needing reading glasses out doors. That was a mistake. I was surprised at how often I wanted to look at a map or something else up close. Today I wear bi-focal sun glasses or a clip-on polarized lense over my indoor glasses.

Wait a minute...
Are you saying that with your 2.5 reading glasses you can't get close enough to the screen to read it while on the bike? And, I'm guessing, not far enough away either? Welcome to tri-focals. Try a 1.5 reading lens for on the bike. This puts the sweet spot a bit further out. That's what I have to do for my computer glasses. I can't sit far enough back for the tops, or close enough for the bottoms. I need something in between--tri-focals. In my case it's a .75 difference
Once you figure out what you need, get it in bi-focal sunglasses.
Better yet, take the eye-to-subject distances you need (measure, don't guess) and see an eye doc to get a good prescription. With advancing age, there's more to a good eye exam than simply getting things in focus.

I have several pair of bifocal safety glasses in clear, yellow and dark. They provide UV protection and the optical properties appear adequate. I have a Garmin 705 and use the backlight to enhance readability, but this would be the case with or without the need for magnification. I mostly use the clear lenses as ordinary safety glasses.

I use stick-on bifocal patches with my regular riding sunglasses. I actually only put a patch on the right eye. I just use that one eye when looking at close objects such as the bike computer. It works great for me.

I've also noticed that the Sigma computers have larger speed displays than most. Take a look at a bike shop. That would be a simple fix.
I have two Sigma computers, but don't care for them much, I'll be switching back over to Cateye.
I too wear bifocal safety glasses when cycling. (from this place: http://www.safetyglassesusa.com/safreadglas.html) Clear for night and tinted for day. Off the bike I wear progressive addition glasses - they don't provide enough wind/debris protection. Except for close focusing my vision is ok without glasses. The bifocal safety glasses are cheap.
