Your glasses should sit firmly on your face, allowing you to look out of the center of the frame with the widest range possible on all sides. Over time, especially if they have undergone trauma, glasses may become bent or off-center, causing them to sit crookedly or uncomfortably on your face. Adjusting your own eyeglasses is a straightforward procedure that you can perform at home.
Instructions
things you’ll need:
Small flat-head screwdrivers
Small Phillips screwdrivers
Needle-nose pliers
Plastic Frames
1 Place the frames on a level surface and see whether they wobble. A well-adjusted set of frames should sit squarely on the frame. Note areas that seem to be loose or that are raised higher than others.
2 Tighten the screws at the temples of the glasses, where the eye pieces are screwed to the rim. A very small Phillips or flat-head screwdriver will fit the frames.
3 Grasp your frames gently and bend them back into place if they are drastically askew. Exert only a very small amount of force on the glasses to make sure that they do not snap.
4 Try on the glasses. If they still do not fit, take them to an eye doctor. Plastic frames are more brittle than metal frames and should not be handled too roughly. An eye doctor can put the frames in a hotbox and soften the plastic, bending them back into shape for you.
Metal Frames
1 Evaluate the problems that your metal frames are giving you. The adjustment necessary depends on the problem you are having.
2 Grasp the corner of the frame where the ear-pieces join the rims with a pair of needle-nose pliers and twist the ear pieces up or down if the glasses are sitting crookedly on your face. Be gentle, because you do not want to snap your frames.
3 Grasp the metal arms that hold your nose pads gently with a pair of needle-nose pliers and move them in towards each other if the glasses are sitting too low on your face. Move them away from each other if they are sitting to high.
4 Grip the ear pieces on either side of the curve that hooks over your ear. Bend them in or out depending on how they sit. If they rub the back of your ears raw, bend them out. Bend them inwards if your glasses are constantly loose.
