In addition to the biggest change of all, which has received the most ink: Google Glass, a pair of glasses that are not really glasses, but a computer that is worn on the face, like a pair of glasses.
You have undoubtedly heard of Google Glass, its innovations and its drawbacks. Even though it won’t be released for purchase to the general public until next year, it’s already getting angry pushback from people disturbed by the invasive privacy implications of Glass users being able to videotape or photographing them surreptitiously, who have coined the term “Glassholes”.
Google’s competitors, including Sony, Nokia, Microsoft, and Apple, among others, are rushing to improve a product that is not yet available for purchase.
(Some software developers were allowed to buy and test Google Glasses prototypes for $ 1,500 each.)
But other companies are creating computer glasses for specific purposes. Recon Instruments, for example, is developing smart glasses for skiers, who red green colorblind glasses will be able to see their speed, elevation and distance, among other data, right inside their ski goggles.
2AI Labs is developing another type of futuristic glasses. Its O2Amps are designed to detect changes in blood flow to a person’s face. Blood flow indicates your emotional state, as well as possible bruising or other trauma under the skin.
Doctors and nurses would find this app helpful, as would law enforcement personnel, poker players, and the spouse whose partner got home suspiciously late.
However, none of these glasses are prescription glasses that will correct or improve your vision. Google Glass and all these other smart glasses will need to be worn over prescription glasses or configured to include the user’s prescription.
No, for prescription eyewear innovations, the main focus, so to speak, is on glasses that replace progressive or bifocals. Some people just can’t get used to having their reading and distance (bifocal) recipes or their reading, computer and distance (progressive) recipes in a single lens.
These multifocal glasses will be the right ones for them. They have lenses that range from distance to computer to reading vision, all at the touch of a button, slider, or dial, like the focus knob on a pair of binoculars.
Is that how it works.
They wear glasses with outer and inner lenses. The outer lens has distance vision and the inner lens contains liquid. One company uses a slider on the bridge of the glasses that activates the inner lens that contains liquid.
By adjusting this slider, you can adjust the correction of the glasses to the type of vision you need: far, intermediate or near vision. Change the shape of the lens similar to the way a makeup or shaving mirror can be rotated to get a magnified image.
Another company is also using two lenses per eye. But instead of a slider, you’re embedding a processor chip in the glasses to change focus automatically when the wearer’s head tilts or when the wearer touches a button on the frame.
Do you want to save money and share your glasses with your partner? With these glasses, spectacle wearers can program two different prescriptions so that one family member can use them when the other person is asleep or with a different pair of glasses.
At over $ 1,000 a pair, these glasses are unlikely to catch on with the eyeglass-wearing public, who are starting to buy their glasses at deep discounts from online retailers.
Not only that, but some domestic disputes could arise if both parties want to wear the glasses at the same time. At least the hefty price tag should serve as a deterrent to the tug of war on glasses.
However, along with the exorbitant cost, there is another problem with autofocus glasses: Most eyeglass wearers also have astigmatism, which makes everything blurry if left uncorrected. This is something that autofocus glasses cannot do.
People with astigmatism may not benefit from 2.0 glasses, but people with color blindness do.
EnChroma glasses use a coating on eyeglass lenses to make red and green objects stand out. But you are thinking of spending more than $ 500 for a pair.
