Will the contact lenses melt in my eyes when the weather is hot?
Hello, no.
Contact lens lenses themselves are made of water-containing material, how could they melt! Currently, there are two main materials for contact lenses on the market, one is hydrogel and the other is silicone hydrogel.
The last step in the production process of contact lenses is "high temperature and high pressure to confirm the effectiveness." This process is to expose the contact lenses to a temperature of 126 degrees Celsius for more than 15 minutes to ensure the high temperature resistance of the contact lenses. Contact lenses will not melt at high temperatures of 131 to 150 degrees Celsius. This means that the temperature that human skin can withstand can be tolerated by contact lenses.
