Can I Leave My Sunglasses In The Car?

By Essilor News

July 14, 2016

Summer is officially here and you’ve been showing off your latest pair of sunglasses to friends and family. Your sunglasses are the summer go-to item for their functionality as both sun protection and a fashion statement. Because you probably made a large investment in your new shades, you want to ensure they last as long as possible.

We all leave things in the car so they’re easily accessible. But should you leave your shades? With the temperature increasing by the day, it is important you do not leave your sunglasses in the car. Since car temperatures can reach upwards of 200 degrees Fahrenheit, always take them with you.

What does happen if your sunglasses are left in a hot car?

  • Mirror and anti-reflective coatings on the lenses can be damaged. Although it’s tempting to store your sunglasses in the compartments in your car, especially the ones specifically designed for that function, high temperatures can ruin your lenses.
  • In some cases, the heat will cause the coating on the lens or even the lenses themselves to crack. This cracking will ruin your lenses and make it impossible to see through them.
  • In extreme cases, the frames can lose their shape and become loose around the ears, which in turn, could cause the lenses to loosen or fall out.

Make a point to put your sunglasses in a case and carry them with you so they’re kept out of extreme heat. This simple change in behavior can help your sunglasses stay in excellent condition all summer long.
