In the previous article, we discussed “What are the best designer glasses?”. In this article, let’s talk about “Can fake glasses affect your vision?”.
Can wearing glasses deepen myopia?
Most people develop myopia in their teens and have to wear glasses. But as it happens, teenagers' bodies are still developing, and the axis of the eye grows as the body develops. It makes myopia worse. Therefore, it is not proper to simply attribute the increase in myopia to wearing glasses. True myopia may deepen faster if you don't wear proper glasses.
Mismatched glasses deepen myopia.
If the effect of regulatory myopia is not excluded during optometry, the degree of regulatory myopia will be included, which will bring a large error to the degree of optometry. It may be possible to see clearly with these glasses, but not comfortable. They bring the eyes a greater burden. They will even feel dizzy.
Poor-quality glasses affect eyesight.
Cheap eyeglasses material has no strict screening. If the lens material is unqualified, the things are not clear, large dispersion, seriously affecting vision. Luminosity distribution is uneven. The Refractive index is below the requirements. The visual effect is not clear. And the lens color is gray, so it is easy to cause eye fatigue. Inferior glasses resin matrix is impure, so can cause deformation or dizziness. The center point of the lens is not in the same straight line, and the pupil distance is not consistent, which will cause visual fatigue, vision loss, and other hazards.
Inferior glasses are easy to break.
Shoddy glasses are produced in unlicensed factories with poor equipment and low cost. Due to poor scratch resistance, the lenses are prone to scratch. The lens film is easy to fall off, and the quality of anti-fouling, anti-reflection, anti-static, and other aspects is poor. It has poor impact resistance and can easily come off at the hinges and welds. Poor elasticity, they are brittle and easy to break. They have poor surface luster and color, poor corrosion resistance, easy to rust, easy to change color. The smelting process is poor, low purity, containing more impurities. For the frame processing technology, inferior glasses' surfaces are rough and uneven, having a dark color. Electroplating technology is not good, easy to decolor.
