Popular knowledge about glasses

Many friends who wear glasses will find that their glasses become crooked after wearing them for a long time. Such "one high and one low" glasses actually have a great impact on eye health!

Taking off glasses with one hand is the most common way to cause the frame to deform, because for most glasses, the frame and the temple are connected by hinges, and there are screws or springs in the middle. When taking off and putting on glasses with one hand, one side will be pulled apart, while the other temple will still be against the face. At this time, the temple and the hinge will be pulled outward, causing uneven force on the temple and causing the glasses to become crooked.

What kind of glasses are correct?

A pair of glasses frames are mainly composed of the following parts: the lens ring, the bridge connecting the two lens rings, the nose pads supporting the nose, the temples hooking the ears, and the piles and hinges connecting the temples and the lens rings. Once any part is deformed or displaced, it may cause the glasses to be crooked.

The glasses are not suitable for high and low ears

Most people's faces are not completely symmetrical, so it is possible that one ear is higher than the other, which can indeed cause the glasses to be unbalanced. However, as long as they are properly adjusted by professional spectacles fitting institutions, they can be worn comfortably.

Long time no maintenance

Glasses are correction tools that need to be worn every day. Over time, even if they are adjusted well before, the temples will open and close frequently, causing the screws to loosen or the nose pads to become stiff due to excessive accumulation of dust and grease. Therefore, it is recommended that everyone develop the habit of regularly inspecting glasses.

The harm of wearing crooked glasses for a long time

The degree of the lens is not the same at every angle, so if the glasses are crooked, the degree of what you see will be different. If you can't adapt, you will feel dizzy, painful, nauseous, etc. In addition, theoretically speaking, the standard of eyeglasses is not only the degree of the lens, but also includes: the distance between the lens and the eye, the distance between the pupil, the angle of the lens surface, and the angle of forward tilt. This series of parameters will change with the deformation of the frame.

How to straighten glasses

If you find that your glasses have been deformed, the best option is to take them to an optical shop in time and ask a professional to adjust them.

In addition to protective glasses, how should we protect our eyes in daily life?

Look into the distance regularly: Looking into the distance can adjust the ciliary muscles of the eye and prevent them from going into spasm.

Eye exercise: First, slowly and forcefully turn your eyes to the right, then move your eyeballs to the middle, and then slowly and forcefully turn them to the left, repeating this 2-3 times. Next, turn your eyes downward and upward, repeating this 2-3 times, to relax the spasmodic extraocular muscles. You can also close your eyes, rub your palms together to warm them up, and then place them on your eyes for a hot compress.

Blink moderately: Blinking allows the tear glands to secrete tears, which moisten and wash the cornea, making it smooth and keeping the eyes moist, which can effectively prevent dry eyes and other discomfort symptoms.

Screen settings: When using a computer, you should also pay attention to setting the brightness, saturation, and hue of the computer screen to keep the screen brightness neither too bright nor too dark. You can also adjust the angle so that the computer screen is tilted slightly downward for eye comfort.

Eat eye-protecting foods: Eat more foods that are good for the eyes, such as cod and other deep-sea fish. Deep-sea fish are rich in DHA, which has a certain effect on preventing the formation of cataracts and protecting the retina.

In addition, vitamin A is very beneficial to the eyes. Regularly eating foods containing vitamin A, such as carrots, lamb liver, egg yolks, etc., also has a certain protective effect on the eyes.
