Can you adjust your glasses by yourself?
If your frames are not suitable, adjusting your glasses at home may be easier than you think. You can solve the most common problems in the frame by yourself, but sometimes taking your glasses to an optician is the best thing to do. Of course, if your problem is your lenses, that's something you can't usually fix at home.
The frame needs to match the face shape.
Based on the basic principle of modifying the face shape, avoid wearing frames that are too similar to your face shape as far as possible, so as not to cause the lines of the face to be overly emphasized. The combination of the glasses and the face shape determines whether the glasses are suitable for you or not. Usually, we use the shape of the glasses to modify the shortcomings of the face shape. For example, for a man with a square face, round glasses are more suitable.
How can you tell if blue light glasses work?
It can be identified in the light. Ordinary lenses have a yellowish feeling under the reflection of light, while the anti-blue lens film color has blue on the yellow-green film, which is the cause of reflecting blue light out. Check the instruction manual to verify that the lenses contain radiation-resistant materials. When wearing, you can look at the electronic screen far away, and check if there is a sense of irritation to the eyes. The biggest difference between the regular lens and the anti-blue lens is the coating layer. If you look carefully, you can see that the anti-blue lens layer is very clear. Put the anti-blue light glasses on the fully open phone screen and observe if the covered area is blue. If it is, the prevention effect is good. This is because the blue light emitted by the phone is reflected on the phone screen by the lens.

How to know if lens is polarized?
Make use of LCD screens. Point the glasses horizontally at the LCD screen and then rotate them upward by 45 degrees clockwise. If it is a polarized lens, it will show a change in color deepening. If it does not change no matter how you rotate it, it is not a polarized lens. You can borrow another person's polarized lens or have previously worn a known true polarizer, and place it crossover with the new glasses you want to buy. At this time, you should see the object clearly from the crossover part with your eyes. Then cross the glasses vertically and horizontally, and at this point, the opposite object should not be visible from the intersection. If this condition is satisfied, it means that a true polarized lens is being tested.
