Making your glasses a tighter fit will prevent them from sliding down your nose. Cleaning your face and glasses to remove any dirt or sweat can also stop them from sliding down your face. 

We highly advise that you visit an optician and ask them to adjust your prescription glasses for you. If you go to your regular optician, they will usually do this for free, or for a very small fee. If for any reason you cannot reach your optician, here is our short guide on how to adjust your glasses yourself.

How to adjust your glasses at home


In just a few simple steps, you can adjust your pair of glasses to stay functional, as well as ensuring they feel the most comfortable.

Deciding on what adjustments to make

Before you adjust your glasses, you need to decide what the problem is. Here are some various problems you may encounter:

  1. The glasses are loose or sitting crooked
  • If the glasses are loose or sitting crooked, you’ll need to adjust the arms. Here’s how:
  • If the glasses are loose-simply heat up the plastic temple part of the frame and bend the arms towards each other around the area of the temple tips.
  • You can heat up the frame by using a hair dryer. Simply apply the heat for 20-30 seconds.
  • The temple arms may become crooked and bent over time, often tilting to one side. Lay your eyeglasses upside down on a flat surface. Both of the temple arms should rest evenly without looking bent. If they do not, you will need to adjust them.
  • If the temple arms are crooked make note of whichever side sits higher and bend the opposite temple arm down at the hinge or where it bends behind your ear.
  • If the left lens is higher than the right lens, bend the right temple arm down.
  • If the right lens is higher than the left lens, bend the left temple arm down.

Top tip: We only recommend doing this with wire metal frames. Plastic frames with thick temple arms may need to be heated to adjust; we do not recommend trying this at home. You should seek the assistance of your optician.

  1. Your glasses are too tight or are sliding down your face
  • If your glasses are too tight or are sliding down your face, you may need to run the temple tips under warm water for 30-60 seconds before bending them into place. You can also use a hairdryer for 20-30 seconds.
  • If your glasses are too tight- carefully bend the temple tips upwards to relax the curve.
  • If your glasses are too loose- bend the temple tips downwards to add curve.
  • Try them on again and check if the fitting is better. If not, repeat the same process until you are satisfied with the fit of your glasses.
  • Top tip: Whatever you do, avoid putting your lenses under hot water as this can damage them.
  1. One lens is closer to the eye than the other
  • If your left lens is closer to your eye than your right lens, either bend the left temple arm in or the right temple arm out.
  • If your right lens is closer to your eye than your left lens, either bend the right temple arm in or the left temple arm out.
  1. Your glasses are pinching your nose or are sitting too high/low
  • Nose pads or nose pieces are a common feature on glasses, they are designed for added comfort, but as they are adjustable, over time, can move out of place.
  • If your nose pads are out of place, simply tilt them back into a position that sits most comfortably on your nose, they should slip back into position when you move them.
  • If your glasses are sitting too low – push the nose pads closer together using your thumb, until they fit comfortably on the sides of your nose.
  • If your glasses are pinching the nose – push the nose pads away from your nose until they feel comfortable.
  • Top tip: Be aware that with metal frames, you should have a space between your nose and the bridge of the frame so that it doesn’t dig in. There should be no space with plastic frames and if there is you may not be wearing glasses suitable for you.

Please note: Some frames can’t be easily adjusted due to their material. Titanium, memory plastic and aluminum alloy frames, for example, are resistant to adjustment and will not bend easily.

How do you tighten screws on glasses?


On the inner section of the temples (where the eyeglass frames and arms meet) you will usually find incredibly small screws. Tighten the screws using a mini-screwdriver. 

If you find your glasses very quickly becoming loose again, you may need to replace the screws.
