Sales points of note for color changing lens
The discoloration rate of the lens is related to the intensity of ultraviolet light. The stronger the ultraviolet light is, the faster the discoloration rate will be, while the vice versa. The degree of discoloration is related to the ambient temperature. The higher the temperature is, the color of the lens is slightly lighter. Otherwise, the color is slightly darker. With the progress of manufacturing technology, the discoloration rate, especially the fading rate of the discoloration lens has been greatly improved, and the interference of temperature on the color depth is becoming less and less. Either glass or resin lenses react only with ultraviolet light, not visible light, so in some environments, they do not darken.
Wear blue light glasses before bed.
Because blue light can have a huge impact on your sleep cycle, these glasses are pretty important before bed. So, putting on blue light glasses before you go to bed can help increase melatonin, which in turn helps you get a good night's sleep. Sleep glasses display a wider range of blue light, which naturally helps you sleep better and triples melatonin production. They have a slight lens color because they target a wider range of light, but are best for sleeping. In addition to sleep glasses, there are nearly transparent optical glasses that filter out blue light levels to help treat digital eye strain, which is made up of headaches, blurred vision, and eye strain.

Features of progressive lenses
With the proper head position, the wearer can have a clear and continuous vision at all distances from the distal point to myopia through the progressive lens. When the eye moves from one area of vision to another, the eye adjustment process is natural and smooth, without any visual fluctuations. With natural vision and better adaptability, it is in line with physiological optics. The mid and near vision area is relatively small: Some wearers may feel that the gradient area of the progressive lens is smaller, which limits the width of the saccadic eye and requires increased head movement in order to achieve the same reading range. At medium and short distances, the wearer needs to coordinate certain head movements.
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.
