Can contact lenses really stick to the eyeball at high temperature?

Most contact lenses are made of silicone hydrogel, which is a kind of organic polymer material with stable structure, and its ignition point is above 100 degrees. The high temperature in summer is not enough to change its nature, so don't worry that glasses will stick to the eyeball.

Contact lenses themselves are resistant to high temperatures. For example, in the high temperature of barbecue, contact lenses can protect our own corneal tissue, like a heat-resistant barrier. Regular contact lenses are hard and soft, and the material is not ordinary plastic. Hard contact lenses are usually made of siloxane methacrylate, while soft contact lenses are made of polymers. Their melting points are generally around 160℃. After wearing it, the lens will not melt even if it is close to the fire source.

Contact lens, also called contact lens, is a kind of lens worn on the cornea of eyeball to correct vision or protect eyes. According to the hardness of materials, they are divided into hard, semi-hard and soft. Contact lenses not only greatly improve the appearance and convenience of patients with myopia, hyperopia and astigmatism. And the vision is broad and vivid. In addition, it also plays a special role in controlling the development of myopia and astigmatism in adolescents and treating special eye diseases. Hospital experts remind that wearing contact lenses requires a detailed examination at a regular hospital or optician. Choose contact lenses that suit you and pay attention to eye hygiene to avoid causing other eye symptoms. If you feel uncomfortable after wearing it, go to the hospital for examination in time.

The vision correction effect of high myopia and high astigmatism contact lenses is better than ordinary glasses, and the field of vision is not limited by the frame, but it is not suitable to wear them for too long, because if you wear contact lenses for a long time every day and stay in an air-conditioned environment for a long time, dry eyes and fatigue are inevitable. In addition to blinking more and taking more rest, try not to wear ordinary hydrogel contact lenses for more than 12 hours, do not take a nap without glasses, and do not sleep at night without glasses. In addition, nearsighted people suffering from dry eye, long eyelashes, entropion or ectropion of eyelids and high temperature and dusty living and working environment are advised to wear contact lenses with caution.
