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 to ensure a firmer fit. If this isn’t enough, we’d 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 you’re starting shape. Frame adjustments should be made in small increments as only minor adjustments are usually 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.
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 does not cause the arms to move. They should also be loose enough that they don't bend or strain when opening and closing
To tighten your sunglasses, determine if you have phillips heads or flat head screws. It's important to use the correct screwdriver and having a few quality screwdrivers around the house will pay for themselves over time.
Grip the sunglasses firmly and tighten carefully. About 5 degrees, is normally 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 dab the screw head (and screw bottom if exposed) with clear nail polish. This will help to protect it.
Plastic Frames can be adjusted with the right amount of care and consideration. Take your time and follow the pointers below.
IMPORTANT: We suggest soaking the frames in very hot tap water for about 30 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 you’re going.
If you need to bend the arms, bend them about twice as far as you need too, and hold for 10 seconds…then release. Check them against your traced pattern. Repeat this until desired adjustments are made.
Go slowly – it is better to make multiple small adjustments rather than risk breaking the frames.
In most cases metal frames can simply be bent by hand. As previous, 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. Frames will almost certainly scratch if you don’t first protect them from the hardened steel of the pliers.
