The truth is, though, that 2013 has been the Year of the High-Tech Glasses in
other, quieter ways. At least three new eyeglass technologies have arrived.
They’re not intended to bring the Internet to your eyeball. They have a more
traditional goal: improving your vision.
Here’s a look at three.
ADLENS VARIABLE FOCUS Yes, it’s an unfortunate name; Adlens glasses may be the one place in today’s world where you won’t encounter advertising.
“Ad,” in this case, is short for “adjustable”; these are variable-focus glasses. The lenses of the Lennon and Hemispheres styles ($80 and $100; adlens.com) are filled with liquid, and cylindrical plastic knobs protrude from the sides. By turning the knobs, you precisely adjust the liquid pressure on a curved membrane inside the lens, affecting its power (from –4.5 to +3.5 diopters). They can handle even severe nearsightedness or farsightedness. They don’t work for the blurriness of astigmatism, but they’re perfect for presbyopia (better known as “over-40-reading-glasses-syndrome”).
There are distinct advantages to variable-focus glasses like these. First, you can tweak the lenses independently for each eye. Second, you can adjust them for different situations — tired eyes often need more help — or even different people. They’re a natural for restaurants, which can hand them out to patrons who’ve forgotten their reading glasses.
Third, you can adjust them yourself, without requiring an eye doctor or a prescription. That’s a big deal in poor countries like Rwanda, where, Adlens says, there are 10 million people but only 14 optometrists. Even though a million Rwandans need glasses, almost nobody has them, according to the company. When you buy a pair of these glasses, Adlens donates a pair for distribution in Rwanda.
The Lennon and Hemisphere styles look goofy because the lenses are perfect circles, like half dollars, which isn’t a design that will suit many faces. (They’re available in a wide range of frame colors and lens tints.)
Furthermore, the adjustment knobs are big, ribbed and absurd looking, sticking out beyond the frames. Once you’ve dialed up the perfect focus, you can snap off the knobs, but then the glasses are no longer adjustable. You’ve locked in that “prescription” forever.
You can leave the knobs on, so that you can dial up different focal powers at different times. That’s fine if you don’t care what you look like (at home in bed, say), but you wouldn’t want to wear them in public like that.
The third Adlens style, Emergensee ($40), is slightly more conventional-looking. Its adjustment knobs are much smaller and less conspicuous. They stay on, so you can always adjust the focus.
These glasses don’t have liquid inside; instead, each lens has two panes that slide past each other when you turn the knobs, so they still look a little odd. But Adlens promotes them as an ideal spare pair for the glove compartment or kitchen drawer.
The best, Adlens says, is yet to come. This fall, it will offer liquid-lens technology, for the first time, in normally shaped, designerlike frames. Stay tuned.
O2AMP COLOR-ASSISTING GLASSES O2Amp makes tinted-lens glasses for the medical profession. According to the company, these glasses give doctors a “clearer view of veins and vasculature, bruising, cyanosis, pallor, rashes, erythema, and other variations in blood O2 level, and concentration,” especially in bright light.
But the purplish pair, the Oxy-Iso ($302), has an unintended side effect, the Web site says: they “may cure red-green colorblindness.”
I just about hit the ceiling when I read that. Like about 8 percent of the male population, I’m colorblind; I have severe red-green colorblindness. That is, I see far less red and green than you do. I can’t tell blue from purple, or green from brown. And I fail miserably on those colorblindness tests where you try to see hidden numbers among colored dots (Ishihara plates).
Unfortunately, the Oxy-Iso glasses did nothing for me. I still failed the Ishihara tests.
