Dual Eyewear sunglasses provide bifocal lenses for reading bike computers
Electronics have become a ubiquitous part of fitness and recreation. You use a GPS to navigate and track your speed, distance and vertical. You use a heart rate monitor to measure your calories burned and heart rate. You load your iPhone with all kinds of music and apps to power you through. Heck, you may even load your sneakers with electronics.
While electronics can enhance your experience, they can also be dangerous if you're spending time trying to get a readout rather than paying attention to the ground in front of you. What you need is to be able to glance at the display for a half a second, get the information and then put your eyes back on the road. Thing is, the compact nature of watches, GPS units and bike computers can make them difficult to read at a glance, especially if your vision isn't perfect.
Dual Eyewear sports sunglasses integrate bifocal-like lenses, putting a small magnification zone in the lower, inner corner. Look through it and get the magnifying power you need to see those numbers quickly and surely. The greater lens is just a regular polycarbonate sunglass lens. Several reviews that we've read indicate that magnification works effectively without hindering regular vision.
Dual Eyewear sunglasses come in three different magnification levels, +1.5, +2.0 and +2.5. The company suggests that those looking to use the sunglasses in the car, motorcycle or bike drop down a level from what they'd use when reading a book. Sunglasses are offered in several frame styles with brown or smoke lenses. Interchangeable lenses in amber and clear are also available for the SL2 model. The retail price of all models is US$49.95.

Or you can order glasses from zenni optical dot com, put in zero power for sphere, and add a bifocal of 1.50 (or whatever reading glass power works best at the distance you read on your bicycle). Probably about $32 shipped.
I have been using a similar product for years .... Industrial Supply houses sell "safety sunglasses" with the reading lens insert they look fine, and cost less than $10 a pair.
The advice on magnification is good, if you use say a +2.5 reading lens, then for a bicycle, car, motorcycle use you will only want a +1.5 or +2.0 ...
I thought there was a difference between the numbers on "reading" glasses and magnifyers. Magnifyers have been used by card sharks for years, but I never saw a mention that these were the easily available...but I did hear they went to the doc and got the scripts...along with a slight rose tinge to show the markings...
so is mag the same as distance correction, or No?
I like the idea of these. Being a keen cyclist myself, anything that makes its safer for cyclists on the road can only be a good thing. They look pretty good too.
