HOW MUCH  GLASSES DO YOU HAVE ?
Most people have more than 10 pairs of shoes but have only 1 pair of glasses and 1 pair of spare glasses (which is really essential, especially if you have a higher dioptre: more than 1 or -1). Glasses are more important to show your personality rather than shoes.

ALL-ROUND GLASSES DON'T EXIST

•  DEPENDED ON YOUR ACTIVITIES: you can not sport with glasses and go to a fancy evening diner with the same glasses. It's the same with clothes, you don't wear the same things to sport and to go out.
• DEPENDED ON COLOURS: nowadays different frames are available to click on your glasses, thereby you can change the colour and shape of your glasses and it's not nessesary to buy antother frame.
• DEPENDED ON THE LIGHT: If you choose stained glasses (photo chromatic glasses ") you can wear them in all light conditions. Unfortunately those glasses don't darken from behind windows. So you still nead good sunglasses (very important for drivers!) 

 
BY THE AGE OF 40 YOU WILL FEEL THAT YOU NEED  DIFFERENT DIOPTRES  With progressive glasses you can see everything: far , closeby and in between, but it's still a compromise. That's because you look through a small layer. You can take seperate glasses for certain functions:
 

• FAR: glasses for distance are well appreciated by many drivers, because the side view (eg for side mirrors) is much better.
• DISTANCE BETWEEN: computer and office work, music playing, glasses for reading,
• CLOSE: Reading with separate reading glasses is much easier than reading with a double vision goggles. For fine sewing choose extra strong reading glasses
