How to Adjust Plastic Sunglasses
Plastic sunglasses can be fun, coming in a variety of shapes, colors and patterns. They are a very cost-effective alternative to expensive custom sunglasses. However, because they are fitted specifically for you, it may be necessary to make your own adjustments.
Bridge Adjustment
- Visit your local glasses store or optometrist and ask if you can use their hot box. A hot box is a device that is heated to a specific temperature to soften plastic. The box contains small glass beads or sand that allows for heat transfer.
- Decide how you want to adjust your sunglasses. If the frame is too wide (caused from repeatedly placing your glasses on your head), you will want to make the bridge of the glasses smaller. Likewise, if the frame is too small, you will want to widen the bridge.
- Place your glasses into the hot box (to make the plastic malleable) for approximately three seconds and then remove them. Depending upon the adjustment you are making, apply pressure in the correct direction on the side of the frame to curve the frame inward or outward, adjusting the glasses at the bridge. Be careful not to apply too much pressure, or you will overcorrect your sunglasses.
- Try on your sunglasses to see how they fit. If they are still not to your liking, you can repeat the process until you have reached the correct adjustment.
Temple Adjustment
- Place your glasses on a flat surface. If one side is sitting higher than the other, a temple piece (otherwise known as a side or an arm of the glasses) needs to be adjusted.
- Grasp the temple piece that needs to be corrected with one hand and the lenses piece with your other hand.
- Straighten the frame by bending the temple piece up or down, depending on how the adjustment needs to be made.
