Specs
The first and main thing to remember is that your specs will sit on your face every day for the next 2 years or so, you want them to fit and be as comfortable as possible.
 
You'll also want them to look good and give as clear vision as possible.
 
Most people tend to think in terms of the frames but in reality it's the lenses that will have the major impact on weight and appearance.
 
Recent trends have been towards metal frames. The majority of these now have sprung sides which make them more comfortable to wear and more resilient.  Materials include stainless steel and titanium, these add to the strength and help to keep the frames light. Titanium also has a "memory"
