1. Don't just reach for your tissue, tie or sleeve to clean your glasses – you're not doing your lenses any favours. Don't forget: proper lens care increases the longevity of your lenses and ensures better vision. Even when you're on the go, make sure you use cleaning products from trusted experts in the optics industry.

2. Don't wash microfibre cloths in water warmer than 40° C and don't add fabric softener – otherwise the cloth will leave streaks the next time you clean your glasses.

3. Scratches can't be wiped away, no matter if you have plastic or glass lenses. In this case, prevention is advisable because scratched lenses should be replaced immediately. Even if the defect only appears cosmetic, light disperses through the tiny scratch, irritating the eye. That's why it's important to clean your lenses with a special, microfibre cloth.

4. Your glasses need a home! Store them in a hard case whenever you're not wearing them. If you don't have a case with you, make sure you put them in a safe spot with the lenses facing upwards.

5. Glasses don't like extremely high or extremely low temperatures. The heat generated in a car on a hot summer day, for instance, is also something to be avoided. The same holds true for the sauna or the heating at home. Don't subject your glasses to extreme temperatures more than is necessary.
