Choose cost-effective lenses.
People who have high degrees choose the lens with a high refractive index like 1.60. So that the child's nose will not be compressed, which is the concern of most parents. Children grow faster, and the glasses replacement cycle is short. Adults should choose better quality lenses when choosing lenses, because a pair of glasses can be used for years, even in the situation when the frames are badly distorted and the lenses turn yellow. Zeiss A series lenses are cost-effective, suitable for people who are short of money and want quality. Nikon lens quality is very good, the film, wear, and sharpness are excellent. The disadvantage is that it is expensive, and the price gradient is quite large. The price scope is a bit wide, with two different refractive indexes.
Frame Selection of Progressive Sunglasses
Choose a proper frame range. Only if the frame is not very large and beveled, the frame can be very flat. Because the distance from the glazed to the optical center of a progressive multi-focus lens is 19-17 mm, and the distance between the edges of the frame will be no less than 28 mm if the area inside the lens can be used at close range while maintaining the far sighting field.

Why do so many people like rimless glasses?
Rimless glasses are lighter because they have no frame and are made of memory titanium alloy, which greatly relieves the pressure on the bridge of the nose and eyes and makes them more comfortable to wear. And because there are no frames to tie them down, the wearer has a wider view. Rimless glasses style is more diverse and stylish. They are rich in color, so loved by young eyeglasses.
How Should Glasses Fit?
Make sure your pupils align correctly. The combination of frame, arm, bridge, and lens measurement can affect the placement of your pupils within your lenses, which is essential to the proper function and comfort of your prescription. To ensure glasses fit properly, the pupils should align horizontally in the center of your lenses.
Also, you should consider your face shape. When choosing a pair of suitable glasses, you should consider what face shape you have.
How do anti-blue light glasses protect the eyes?
The anti-blue light glasses available on the market, no matter what type, etc., are mainly the difference in anti-blue light effect, light transmittance, and frame, which will affect the cost of glasses. Obviously, the lens is the most important of these. I think that it is basically enough to choose 30% to 40% anti-blue light glasses. It is good to cut off the harmful blue light. It is not necessary to completely eliminate the blue light so that the chromatic aberration will not be too large, the light transmittance is better, and it also has a certain anti-blue light effect.
Of course, to protect the eyes, it is not enough to rely on anti-blue glasses alone. The effect of anti-blue glasses is mainly to reduce the probability of eye diseases, and can not effectively relieve eye fatigue. Normal people between the ages of 20 and 40 blink about 20 times per minute. When you open your eyes and stare at a computer screen that changes rapidly, the number of blinks will be reduced to 4 or 5 times per minute, resulting in serious insufficient secretion of scum and dry eyes. Therefore, no matter how urgent the work is, you must pay attention to the rest of your eyes, close your eyes regularly, use eye drops when needed, and reduce the brightness of the screen as much as possible when looking at the screen. When the brightness of the screen is significantly higher than the ambient light It is easy to cause eye fatigue. Try to use it as little as possible in the dark. To be honest, it is more important to develop a good eye-using habit.
