How to Choose Eyeglasses : Plastic versus Metal Eyeglass Frames
In this clip, host Melissa Russell discusses the difference between plastic and metal eyeglass frames. She states that plastic frames tend to be a little more thick and sturdy while metal frames are lighter and have more flexibility. Because of these differences, customers sometimes prefer to purchase plastic frames for children.
Cleaning
To clean your glasses, wash them with a mild soap and water to remove dirt and oils and dry with a lens cloth. Do not use paper towels as they can scratch glasses.http://blog.szynalski.com/2009/08/20/how-to-clean-eyeglasses/
Adjusting
Adjusting glasses can vary depending on the material and the structure of the glasses. To adjust glasses yourself, apply an even force to gently bend the piece you are adjusting. If you feel unsure about adjusting your own glasses or feel that they may break, bring them in to an ophthalmologists office and have them adjusted there.http://www.eyeglasses.com/blog/page.cfm/glasses/adjusting-your-eyeglasses
The nose pads control how high your glasses sit on your nose. To make your glasses sit higher, take the nose pads and bend them in symmetrically. To make them sit lower take the nose pads and bend them out. Be sure that the two sides match or the glasses will not sit balanced on your nose. It is also important to make small adjustments so that you don't over bend and weaken the small nose pad arms.http://www.eyeglasses.com/blog/page.cfm/glasses/adjusting-your-eyeglasses
