To ensure that your glasses serve for a long time and remain in perfect condition, follow simple rules:

1. Take off and put on glasses with both hands: This will help prevent frame distortion and extend frame life.
2. Use a spray and a wipe: Clean the lenses with special products to avoid scratching them.
3. Do not wear the glasses on your head: This can stretch the frame and affect its shape.
4. Use the storage case for storage: Protect your glasses from damage when not in use.
