The glasses fit nicely on the bridge of his nose. Why is he crooked when he is wearing it?
One of the reasons is that many friends are always used to taking off their glasses with one hand.
This is the most common, and it is very easy to cause the frame to deform. I guess that many of my friends are thinking, oops! I did. When you take off the glasses with one hand, the two temples of your glasses will be unevenly stressed. If you take off the glasses for a long time, the glasses will definitely become crooked.
The second reason is that the ears are asymmetrical.
We all know that the size of our faces, eyes, and ears are not completely symmetrical, and there will be more or less ears that are high and low. If the glasses frame is worn on the ear for so long, he will definitely be deformed and crooked.
The third reason?
That is, the force of your frame is uneven, and a considerable number of people have different degrees of myopia on the left and right sides. Especially if the difference between the two sides is too large, the lens with the deepest degree will be very thick and the weight will increase, so that the heavier side of the lens will definitely bear a lot of pressure. Of course, the glasses will be tilted toward the heavy side.
The fourth reason is the lack of maintenance and maintenance.
