Is There Any Impact of Leaving Sunglasses in the Car During Summer?
2 Answers
Sunglasses left in the car during summer can be very dangerous. Sunglasses have a magnifying effect similar to a magnifying glass, making them prone to spontaneous combustion under sunlight. Below is an introduction to sunglasses-related information: 1. Function: Sunglasses, also known as shades, are protective gear for the eyes under strong light. Wearing these lenses can block ultraviolet and infrared rays while keeping the colors of the external environment unchanged, only altering the light intensity, creating a feeling of cloudy weather with a cool and comfortable sensation. 2. Disadvantages: A good pair of polarized sunglasses can provide a more comfortable driving experience and even offer additional benefits. However, many people tend to leave them in the car after use, which is a very bad habit, especially when placed in front against the glass.
As someone who frequently drives for trips, I've personally experienced the intense heat inside a car during summer. When parked in the sun, the dashboard temperature can soar to 60-70 degrees Celsius, making it absolutely unsuitable for leaving sunglasses there. Plastic frames can easily soften and deform, resulting in a crooked fit that obstructs vision when worn. Metal frames, though more durable, can loosen their overall structure under high temperatures. As for the lenses, the coatings may melt or bubble, damaging their UV protection and potentially harming your eyes. I recommend developing a good habit of storing sunglasses in a dedicated case or placing them in the glove compartment to avoid direct sunlight when leaving the car. This not only protects your gear but also ensures safer driving. Otherwise, accidental damage could lead to costly lens replacements, which is quite a waste.
