Dear MEL Topic Readers,
'Autofocus' specs promise sharp vision, near or far
Nearsightedness is a common vision condition in which close objects
look clear but faraway objects look blurry, which is becoming more common
worldwide, particularly among children, who stare at tiny screens of their smartphones
or video machines for hours every day. In the meantime, as people age, their eyes’
ability to focus on nearby objects tends to deteriorate, a condition called
presbyopia. Bifocal lenses are eyeglasses that combine both prescriptions in a
single lens by splitting the glass into two vertical regions, the upper for near-sightedness
and the lower for far-sightedness. Now, a Finnish eyewear firm is developing high-tech
auto-focus lenses that respond to whatever correction the wearer needs spontaneously
by using liquid crystals. The lenses seem to function quite well, but they need
to be framed. However, even though the frame is packed with technologies, it is
still expected to be wearable, durable, and fashionable. VR goggles are still clumsy
and pricy. When will we have affordable and fashionable autofocus eyeglasses?
Read the article and learn about these innovative autofocus eyeglasses.
