The fundamental advice behind looking good in sunglasses is personal care habits. More advice on proper sunglasses care:
1. Sparkle!! Your sunglasses should be sparkling! Smudges and dirt on the lenses deteriorates your appearance. You should have a spray bottle with professional glass cleaner, along with a fiber cloth. Keep them in your handbag, car, or desk, to make it easy and convenient to use them when necessary.

3. Do not wipe your glasses on your shirt! Apparently, more than half the people clean their sunglasses with a clothing article. The fabric and dust in clothes can easily scratch the lenses. Your best bet is to use moist cleaning towelettes. They are disposable and keep your world sparkling.
4. Modern sunglasses apply high technology on the lenses and frame. Lenses may be bifocal, polarized (to reduce glare), extra thin, made of light materials. Take special care with high tech lenses. As such, never clean them via clothing articles or household dishes and cleaners. The eyewear cleaners are designed to safely and easily remove smudges, dirt, and cosmetics.
