1 . Imagine looking at a view of mountaintops and wondering about the name of each peak. Suddenly, above each mountaintop, a name appears on the sky. The words are not written in smoke by skywriting planes. The words are actually not in the sky at all. They come from tiny computers in contact lenses (隐形眼镜).
Computers have become smaller and smaller over the decades. The first computers filled houses. Transistors (晶体管) and then chips allowed computers to become small enough to fit on a desktop, then a laptop, and finally a phone. When experimenting with further contraction in size, developers often have to deal with the limits of human eyesight, which control how small the computers can be and still present visible information.
One new solution employs microprojectors (微型投影机) to create a readable display (显示) for tiny computers. These machines project computer information onto any surface. Though an impressive breakthrough, there are potential problems. Such public displays can lead to privacy concerns; most people do not want their information displayed on a wall for everyone to see. Besides, these projectors are extremely expensive, and their screens give users headaches.
Babak Parviz, a researcher at the University of Washington, created another solution: inventing a screen visible only to a person wearing a contact lens. Parviz created a computer in a contact lens that uses the wearer’s field of vision as the display. To create the display, Parviz took ordinary soft contact lenses with a wirelessly controlled system. At some point, Parviz says, it will be possible to connect the lens to a remote personal computer device such as a cellphone or a laptop. By looking in a certain direction, the wearer sends the computer visual information about what he or she sees. The device then uses this information to point out the names of peaks.
These contact lenses are inserted and removed in much the same way as ordinary contact lenses. In addition, the computers in the lenses won’t block the wearer’s sight at all. Although now the computers are not on lenses treating eyesight problems, Parviz hopes that someday the technology will progress to that level.

2 . If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.
The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.
It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.
Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said Sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren’t found guilty.
Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn’t stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.
