2Physics could soon make it possible to replace those heavy glass lenses(镜头)on cameras with "metalenses" -materials engineered to focus light at a fraction(少量)of the weight and size of traditional lensing. A team from Harvard University's school of engineering has designed a metalens that ...

Centuries of effort to improve imaging has focused on perfecting and combining lenses to obtain better optical performance and new functionalities. The arrival of nanotechnology has brought to this effort engineered surfaces called metalenses, which prom
The nose pads are dirty, worn out or have turned yellow. It can be helpful to have aneyeglasses repair kitbecause these kits usually have small screwdrivers, replacement screws and a magnifying glass. Some also have replacement nose pads. You can buy an eyeglasses repair kit online or at a...
I've done it twice (on an XTi and a 50D), and I would certainly not characterize it as easy. You need at least three hands (I seem to recall holding the magnifying glass in my mouth), and if they're small with skinny fingers (as mine are), it's a help. (Take that, Donald ...
Glass lenses can be heavy and fragile, so they are not ideal for sunglasses you plan to wear often. However, they are less prone to scratching than plastic lenses. They have low UV protection so you may want to get a UV coating added to the glass lenses to protect your eyes from the...
Infinix also has a bundled tempered glass and headphones that its sister brand decided to remove for good. Swipe Right if the things aforementioned don’t matter and if you value quick charging speeds, a flat display, and a cheaper price tag overall. For consumers with budget constraints, PhP...
