Nokia Beta Labs has released a cool application that will help you get 20/20 vision. Nokia “Magnifier” uses your camera to “improve readability” such as the fine print in the cell phone contracts. The Magnifier comes with a built in stabilizer that reduces your shaky hands and also has a negative filter gives you the ability to switch from light to dark backgrounds for better reading.
As this is still in beta testing, Nokia says should work for any S60 3rd Edition with auto-focus camera support, N95, E90, N82 devices. But will not work yet for the E71, N85, N96. Check out this video of it in action
