Flexon frames are a type of hypoallergenic eyeglass that are made from lightweight, strong, flexible metal. The titanium-based aluminum frames are estimated to be 25 percent lighter than standard metals. These frames are also corrosion-resistant. Flexon frames rank among the most flexible, and Flexon is sometimes referred to as the "memory metal"; these frames have the ability to return to their original shape after being bent, twisted or crushed. Consequently, they are easy to adjust.

Put your glasses on and look in the mirror. You will want to know exactly what adjustments need to be made before you get started. If your glasses have a nose pad, adjust that first. This will be the easiest part of the adjustment because that portion is usually held together by screws and not by the resilient aluminum-silicon combination that Flexon is made out of. Be careful not to over-bend the nose pad. You may need to use a tiny screwdriver to remove the pad and make the necessary adjustments.

Adjust your Flexon eyeglasses in specific parts. Attempts to shape them at the shaft of the temple and on the nose bridge are futile. The tips of the temples are often not made from the flexible material. Look into a mirror and place the lenses directly in front of your pupils. Take note of whether you need to adjust the piece up or down. Use your fingers to grip the joints and make the adjustments. If this doesn't work, try with needle-nosed pliers. The design allows you to ensure the tips of the temples are adjustable to rest on your ears. The two most common objectives are to position the center of the lens exactly in front of your pupils or to make the glasses more comfortable.

Raise one arm of the glasses at the tip of the temple on one side and lower the other to fix glasses that do not sit evenly. Remember to grip the joint tightly. The manufacturer designed the frame for level ears. Often, people have one ear that is slightly higher than the other, so this is a typical adjustment.
