As we get older, our eyes get older too. It’d be nice to be able to have perfect eyes until the day we die but that’s not reality. You can pay for certain surgeries to fix your eyes but those are not cheap. Most of us don’t mind putting a pair of glasses on anyway (especially with prescription lenses available for Google Glass). These Self-Adjustable Glasses are also interesting. You can just turn the dial on each side of the frame to adjust the lenses to your desired local point. These glasses have a power range of +0.5 to +4.0D. Not as cool as Google Glass but not remotely as expensive.
