A common problem for eyeglass wearers is uneven frames. The delicate plastic frame can easily warp during hot temperatures, or become lopsided after being dropped. It's best to go to your local optometrist for a replacement frame or repair, but this is a time-consuming task, and it may be out of your budget. If the damage to your glasses is minimal, you may have luck in attempting to adjust them yourself with hot water.

  1. 1

    Inspect the damage on your frames. Find out where they need an adjustment. You can figure out the problem by trying the glasses on and determining whether both sides look the same. Inspect both of the arms on your glasses to make sure they match up, as well. Sometimes the damage may be subtle and require some time to find. Unfolding your glasses' arms and placing them on a flat surface is another way to determine whether your glasses are lopsided.

  2. 2

    Boil a small pot of water on your stove. Once the water is rolling, carefully pick up your glasses with a pair of tongs on the side that does not need an adjustment. If both sides need to be repaired, then hold the glasses by the nose bridge.

  3. 3

    Dip the crooked part of your glasses into the hot water for 5-7 seconds.

  4. 4

    Pull them out. Using a towel, gently move the soft part of your glasses quickly, so the plastic does not harden before you can fix them. If your adjustment is not successful, repeat the process.

Tips and warnings

  • Always be cautious when adjusting glasses, as you can cause further damage. When in doubt, consult your optometrist.
