The development of glasses
In 1451, Nicholas of Cusa of Germany invented a lens that was thinner in the middle and thicker at the end to help short-sighted people. In 1727, Edward Scarlett, an English optician, invented modern frames that could be worn over ears and noses. Benjamin Franklin, an American scientist, and philosopher invented bifocals, which divide the lenses into far and near parts. The two lenses are held together by a metal frame. Frame construction has improved over the centuries, and today frames have come in different kinds of styles and designs. Unbreakable lenses were invented in 1955, and in 1971 a new type of lens combining plastic and glass properties was invented.
What is a progressive lens?
A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?

What should be noticed about low bridge glasses?
At the same time, the weight of your frame should be evenly distributed across the bridge of your nose or on the nose pad of the frame. If the bridge sinks into your nose, either your nose pad needs to be adjusted better, or you need to find a frame with a wider bridge. In addition, the temple or handle of the glasses should be long enough to fit close to the ear. You should be able to move your head without slipping or slipping off your glasses. In short, for those with a lower nose, a triple match requires that the nose chassis have a thicker or adjustable nose pad, a narrower nose bridge, a wider nose bridge, and a shorter lens. If you have bought a plastic frame in the past or present, you should be able to find the size of your bridge on your current frame. Traditionally, the middle number corresponds to the measurement of the bridge. It is important to look at the position of the bridge on the frame.
