Discoloration time and fading time for color-changing lenses
In general, color-changing lenses take about 30 seconds to 1 minute to darken on average when exposed to sunlight/UV and will continue to darken for about 10 minutes to reach the lens depth of full-color sunglasses. Color-changing lenses of good quality and workmanship are restored to an almost clear and transparent state in 2 minutes and completely cleared in 5 minutes, although the high temperature can affect this. If you want to change a single color change lens, the color of the old and new lenses will be inconsistent. This is because the discoloration performance of the old lens will be reduced due to the long-term use of the discoloration agent. Therefore, in order to ensure the normal use and aesthetic appearance, it is usually recommended to replace the two lenses at the same time.
Choose the right color for your glasses.
Black, of course, is the classic color. For boys, wearing black frame glasses can promote the stereo sense of their facial features. Black is the most recognizable color. Black-rimmed glasses will make the outline of a boy's face clearer and make his appearance more handsome. Silver-framed glasses have all the features of metal-framed glasses. But compared to rose gold, silver is a bit more understatement, and it's very versatile and can be worn by guys with different skin tones. Those with darker skin tones can try deep burgundy shades, like popular brown and amber glass frames. Such a frame won't show too dull and won't show too abrupt. At the same time, it will be more harmonious to use a dark skin tone to foil.
A round face fits on a square frame.
The human face of a round face is shorter. So they had better match the slender frames that take curves slightly to reconcile the whole feeling. Angular and square frames are helpful to modify facial lines (prominent longitudinal lines). This can promote strengths and avoid weaknesses so that your face appears contour.
A Suitable Nose Pad
The Nose pad must fit the nose to the maximum extent possible. If they do not fit, the opticians have special pointed tools. It's best not to adjust the nose pad yourself. A lot of store staff are afraid to adjust the nose pad, just because it is difficult. The general store processing master will adjust the nose pad. The nose pad can be adjusted on the premise of the same rake angle.

Do I need to buy anti-blue light glasses?
Nowadays, mobile phones and computers are used more and more frequently. Whether at work or in life, it is hard to imagine what life would be like without these electronic products. It is impossible to protect the eyes without using these products. Especially on mobile phones, the current LED screen technology has gradually replaced LCD screens, and the self-luminous characteristics have also caused serious fatigue to the eyes, and there is no need to say that blue light is harmful to the eyes. At present, the truly harmful blue light is the wavelength. In the blue light of 400 to 440 nanometers, this blue light easily causes eyesight fatigue. In the case of heavy use, try to reduce the damage to the eyes and protect the eyes, which is also the main reason for motivating consumers to buy anti-blue glasses.
How Do Progressive Lenses Work?
So, how do progressive glasses work? Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescriptions at the top of the lens and increase as you move toward the bottom of the lens. You can move your head position to allow you to focus through different areas of the lens.
Move your head upwards to see something in the distance, and hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up. Apart from the aesthetic improvement of the lens without the line segments, progressive lenses avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals.
