Numerous people throughout the world wear contact lenses to improve their vision, but what happens when some of those people live in areas with extreme weather and geography? Almost anywhere you go, you still can wear contact lens. Here is a list of some of the more particular situations you could experience when wearing.

Hot Weather

  • While using contacts, sweat can sneak in between the lens and your eye, potentially resulting in infections. That is why it is preferable to remove your lenses when entering saunas and spas.
  • The lenses may dry out more quickly in warmer weather, which is one possible negative side effect. Eye drops are frequently the most effective remedy for the moisture levels in this situation.
  • As long as the packaging is still unopened, contacts can be left in the heat without suffering damage.

Cold Weather

  • While you’re wearing contacts, the chilly air and wind may cause them to dry up more quickly.
  • Since the contact lens is so close to your eye, your body heat normally maintains a comfortable temperature for the lenses.
  • At roughly 5°F (-15°C), contacts held in solution have the potential to freeze. They can be left out at room temperature for a few hours and will return to normal as long as the packaging isn’t opened.




Glasses are significantly more sensitive to temperature changes. Extreme temperatures can harm the frame and lens equally; it also makes no distinction between hot and cold.

  • During temperature changes, glasses may become foggy.
  • Extreme heat or cold can cause glasses to distort and change shape (especially plastic glasses). Both the lenses and the frames have a chance of breaking.
  • Extreme temperature variations can cause the lenses to expand and compress. This may cause your eyesight to become blurry the next time you wear them.

What should I do under such temperature?

  • Put on an absorbent headband to stop sweat from dripping into your eyes and irritating or infecting them.
  • UV sunglasses are essential for protecting your eyes from harmful UV rays, they can also act as an additional barrier to stop your tears from evaporating quickly in warm weather.
  • If the weather is causing your eyes to dry out, use eye drops.
  • On a hot or cold day, make sure to remove your glasses from your car and bring them inside.

Knowing how to take care of your contacts and glasses is crucial for keeping your eyes healthy, preventing blurry vision, and preventing any infections.
