Lenses That Always Adjust

Adlens for Reader's Digest

Change your prescription just by twirling a couple of knobs on the sides of your Adlens glasses. The lenses are filled with a bit of clear liquid trapped between two flexible membranes, which respond to the knob by changing shape and thus the power of the lens. Switch each eye’s lens between nearsighted and farsighted use, tweak it for different activities, or share the glasses with others. Or snap off the knobs to lock the prescription in place. Available now, Adlens glasses range from $70 to $150. For every pair you buy, the company donates one to Rwanda, where only 14 eye doctors serve 10 million people.

App for “Trying on” Frames at Home

It’s hard to buy glasses online since you can’t try on frames. Glasses.com offers a free iPad app that creates a 3-D model of your head (the app prompts you through steps to generate the image), so you can then “try on” the site’s thousands of frames at home. You can rotate your head to check out different angles, tap the screen to slide frames up and down your nose, and share pics with social networks to get feedback from friends. When you’ve narrowed it down, you can order four pairs at a time, wear them for a week, and return the ones you don’t want, all with free shipping.

Glasses That Reverse Color Blindness


About one in ten men worldwide has trouble distinguishing red and green colors, but special purple-tinted glasses might help them stop and see the roses. Designed to help medical professionals spot veins under the skin, the Oxy-Iso glasses had a startling side effect: Many color-blind users were able to spot vibrant reds and greens for the first time. They won’t work for everyone, and users are urged not to drive with them because the lens boosts the ability to see red-green colors at the expense of yellow-blue ones. They’re available at amazon.com for about $300.
