It is a struggle that many spectacle wearers face every day, but the days when you are looking for reading glasses could soon be a thing of the past, thanks to a new pair of “adjustable” glasses.
Futuristic glasses can change their strength by rotating the dial, depending on what the wearer is using.
I can change the focus from -5 to +2 in seconds, eliminating the need to carry multiple pairs of specs with you.
The San Francisco-based designers hope their glasses can help people with presbyopia – a condition that affects the eyes’ ability to focus on nearby objects and causes sufferers to need different glasses for different activities.

Futuristic glasses can change their strength by rotating the dial, depending on what the wearer is using.
The adjustable glasses, called VOY Glasses, have a small dial on each arm.
To adjust the lenses, the wearer can simply turn the wheel from the nose to a more negative power or rotate the wheel to the nose for a more positive power.
On its website, the designers explain: “You can adjust one eye at a time, then adjust your view with both eyes open for a more comfortable view.”
The glasses use a technology first developed in the 1960s by Luis Walter Alvarez, a Nobel Prize-winning physicist.
The technology is based on two polycarbonate plates on each side of the glasses, which slide over each other when the wheel is adjusted.
Depending on the position of the plates, the resistance of the lenses is adjusted.
This technology is already used in a number of other settings, including smartphone zoom cameras and medical devices.
VOY glasses come as both eyeglasses and sunglasses and come with a blue light block, anti-glare coating and UV protection.
Currently, they are priced at 79 USD (58.55 GBP) and come in a range of colors – black, turtle, brown, gray, burgundy and white.

This week, the glasses were awarded the 2021 Innovation Award in the Wearable Technology category at the Consumer Electronics Show (CES).
CES normally takes place every January in Las Vegas, with thousands of exhibitors and over 170,000 attendees coming to see a wide range of new gadgets unveiled.
However, in 2021, the convention will move online, with the creation of a new “digital location” with the help of Microsoft as the central hub for the show’s main announcements.
Gary Shapiro, president of the Consumer Technology Association (CTA), which organizes the convention, said this year’s event will “make history” as “his first all-digital show.”
“This new experience will include more than 1,000 exhibitors from around the world, showcasing the latest trends and innovations in artificial intelligence, 5G, digital health, smart cities, vehicle technology and more,” he said.
“Technology will take us further and CES 2021 will illustrate how innovation paves the way for a brighter tomorrow.”
