Storing Glasses in the Car — Why Heat Can Wreck Your Lenses
Leaving your glasses in the car might seem convenient, but here’s the reality: heat is their biggest foe. On a warm day, the inside of a parked car can heat up to over 60°C (140°F). That’s hot enough to warp frames, ruin lens coatings, and even crack the lenses.
What Really Happens When It Gets Hot?
Lens warping: Plastic lenses can soften and bend, which messes with your prescription.
Coating damage: Anti-glare and UV coatings can bubble or peel, leading to blurry vision.
Frame distortion: Metal frames can expand and lose their shape, while plastic frames might shrink or twist.
Why This Is a Bigger Deal Than You Might Think
If your lenses are warped or the coatings are damaged, your eyes have to work harder, which can result in headaches, eye strain, and deteriorating vision. Replacing them can be a lot pricier than just storing them properly in the first place.
