Can Glasses Left in a Car Cause Spontaneous Combustion?

[DiLuna]

Glasses left in a car may cause spontaneous combustion. The lenses of reading glasses and magnifying glasses are convex lenses, which can easily focus light. If light is focused for an extended period, the focal point temperature can become excessively high, accelerating the aging of the interior and, in severe cases, damaging plastic trim panels or even causing the vehicle to spontaneously combust. Therefore, avoid leaving similar lenses in the car on sunny days to prevent accidents. Below are items that should not be left in a car: Flammable and explosive items: Never store them in the trunk, such as lighters, fireworks, etc. If the car's temperature rises too high or comes into contact with an ignition source, the consequences can be severe. Being caught by traffic police may also result in fines and penalty points. Perfume: Perfume is chemically processed under specific conditions. In high temperatures, these chemicals can easily volatilize and may even harm the human body. Direct sunlight can also cause explosions. Reading glasses: Reading glasses are convex lenses that can focus light, leading to excessively high temperatures at the focal point over time, damaging plastic trim panels, or even causing the vehicle to spontaneously combust.
