DIY Frame Adjustments
Hinge Adjustments
Over time sunglass hinges wear and the screws work themselves out. Loose hinges generally imply a looser fit and higher probability the sunglasses will fall off your head or slip when you are wearing them. Hinges should be tight enough that a gentle shake of the sunglasses while you’re holding the lenses does not cause the arms to move. They should also be loose enough that they don't break or strain when opening and closing.
To tighten your sunglasses, determine if you have phillips heads or standard screws. It's important to get proper screwdrivers and having a few quality screwdrivers around the house will pay for themselves over time.
Generally a firm grip of the sunglasses and a slight turn, about 5 degrees, is all it takes. After each turn do the shake test again until the arms don't move but close smoothly.
Once both arms are adjusted coat the screw head and screw bottom (if exposed) with clear nail polish. This will help to protect it.
Plastic and Metal Frame Adjustments
Both Metal and Plastic Frames can be adjusted. You should have a good idea of the adjustment you want before proceeding. If your sunglasses are too large try tightening the hinges first. Tighter hinges on eyeglasses sit firmer on your face.
If tightening your hinges isn’t enough The Sunglass Fix suggests slightly bending in the arms or the nose area. Both arm and nose adjustments will bring the end of the arms closer together thus fitting tighter on your head. First, trace your frames on a piece of paper. It’s important to know your starting shape. Frame adjustments should move in small increments. Usually only minor adjustments are required. Moving the arms in about 1cm at a time is the most we would ever suggest in a single adjustment. After each adjustment you can place your frames back on the traced pattern to see how much you have adjusted the sunglasses.
Plastic Frame Adjustments
Plastic Frames can be adjusted, with the right amount of care and consideration. Just take your time.
First of all, you should have a good idea of how much adjustment you want before proceeding. If your sunglasses are too large try tightening the hinges first. This can help with a poor fit. If this doesn't work we suggest slightly bending in the arms or the nose area to bring the end of the arms closer together.
IMPORTANT: We suggest soaking the frames in very hot tap water for 30 about seconds before adjusting them. Trace your frames on a piece of paper so you know your starting shape. Moving the arms in about 1cm at a time is the most we would ever suggest in a single adjustment. After each adjustment you can place it back on the traced pattern to see how it's going.
If you need to bend the arms, bend them about twice as far as you need too, and hold for 10 seconds. Release. Check them against your pattern. Repeat this until desired adjustments are made. Go slowly - you are better to make multiple small adjustments rather than risk breaking the frames.
Metal Frame Adjustments
In most cases metal frames can simply be bent by hand. We recommend tracing the frame first and making small adjustments until you get the desired fit. Additionally, needle nose or any standard set of pliers can also be used to help with bends in firmer frames.
We recommend covering the teeth or clamps of any pliers with a cloth. They will scratch frames if you do not cover pliers or frames first.
