Why You Should Wear Blue Light Glasses?
However, many of our work and social life revolve around looking at a screen for multiple hours every day. Too much exposure may damage our eyes. So, you need to consider wearing blue light glasses. Here are several reasons for you to wear blue light glasses.
Less eye strain: looking at a screen all day can make you feel stressed or you may experience eye and muscle strain. So, wearing blue light glasses can help you to reduce eye strain.
Better sleep: spending time on a screen before bed can make you feel alert. In the same way, a walk outside sunlight can also help you feel alert. So, if you are unable to turn off your device an hour or two before bed, using blue light glasses may help you sleep better.
Fewer headaches: blue light can trigger migraines and exacerbate headache pain. Blocking blue light with special glasses may reduce headaches.
Lower risk of eye diseases: the cornea and eye lens are able to block out harmful UV light from reaching the retina. But, they can’t block blue light. If the retina is damaged, the risk of developing macular degeneration will increase, which would lead to blindness. In addition, blue light can penetrate your retina and lead to macular degeneration-like symptoms and increase the risk of developing cataracts. So, wearing blue light glasses can prevent this.
From the above information, can you wear blue light glasses all day or can blue light glasses damage your eyes? You may have got the answer. So, if you need a pair of blue light glasses, try Koalaeye glasses. They come in stylish and at a cheap price.
How To Choose Better Night Driving Glasses?
Choose and buy glasses to use a special night with anti - strong night driving lens. The demand is to block 80-90% of the strong lights and harmful lights, and at the same time to make the road more clearly. Choose glasses with thicker lenses, they are more durable and protect the eyes of drivers against irritation and accidental breakage. As common sunglasses and color-changing glasses are only suitable for daytime wear, wearing them at night will seriously affect the driver's vision.
Common light yellow night driving glasses can only block a small amount of light, and is not very suitable for night driving glasses standards. Therefore, in the choice of lenses of night driving glasses, we must do the selection and demonstration of the national authority of the formal institutions to test products, to achieve the desired effect in actual use. Don't buy products that are not up to standards from vendors. Such products not only do not block the lights but may affect the driver to see the road ahead, affecting the safety of the train operation.
Why do spectacle lenses fog up?
The fog on the surface of the lens is essentially related to the saturation pressure and water vapor liquefaction. The air is full of water molecules, which are constantly doing irregular movements. When there is no temperature difference, water molecules keep hitting the surface of the lens and will keep bouncing off. The lower the temperature, the slower the speed of movement. Therefore, when water molecules hit the cold lens from the hot air, on the one hand, they move too slowly to fly out in time. On the other hand, because of the relatively low temperature of the lens itself and its vicinity, the water vapor will liquefy. As a result, more and more water will accumulate on the lens and form small droplets, eventually forming a foggy layer. As the lens heats up, the mist evaporates back into the air, and the fog disappears.

The material of the nose pads
There are many differences between silica gel and PVC materials. For example, silicone can pass ROHS certification and is environmentally friendly. Silica gel is soft and feels good, while PVC products are rough. Silica gel products are soft, while PVC products are hard. Silica gel products are more flexible, but PVC has no toughness. Silica gel products are usually made to be more transparent. Glass frames made of plate material and TR-90 material, are relatively not heavy and non-allergic. Typically, the TR90 frame is cast to form a nose pad attached to the glasses ring. As the plate frame is cut out from compressed materials, the plate frame with a nose pad is usually injected into the nose pad after the frame is made.

What Are Progressive Lenses?
Traditional eyeglasses are usually single vision lenses with one prescription. Progressive lenses are multiple with three prescriptions in a pair of eyeglasses. Progressive lenses let you see comfortably at different distances, allowing you to see close, near, and far without changing your glasses. There are other kinds of multifocal lenses like bifocals and trifocals, but progressive lenses differ because of their smooth transition between prescriptions.
Bifocals and trifocals work similarly to progressive lenses and feature either two or three prescriptions in a pair of glasses. These lenses have definitive lines separating the prescriptions. However, progressive lenses don’t use these lines and allow you to easily transition between prescriptions.
Hence, in the following section, we will show you 6 different types of progressive lenses.
