4. GIVE YOUR GLASSES AN OCCASIONAL TREAT: THE SPECIAL CARE OFFERED BY AN ULTRASONIC CLEANER
The use of ultrasonic cleaners (available online and from specialist stores) at home or by your optician is your best guarantee of thorough, convenient cleaning. This is the gentlest and most effective way of removing dirt. Just a couple of minutes are needed to restore your lenses and frames to their former glory. Important: don't forget to change the water in the cleaner regularly.
And if you don't want to invest in your device, your opticians will be pleased to clean your lenses in their ultrasonic cleaner - ideally every six months. This is part of opticians' standard equipment these days.
THE RIGHT WAY TO STORE YOUR GLASSES
Your glasses deserve a good home to save for a scratch! Store them in a hard case whenever you're not wearing them. It will be helpful for safe for a scratch. If you don't have a case with you, make sure you put them in a safe spot, with the lenses facing upwards and safe for scratch.
It is also important to ensure that your glasses are not exposed to extreme heat. Temperatures of over 80 degrees centigrade can damage even the toughest lenses or frames. Plastic lenses, in particular, should not be subjected to high temperatures.
This could harm the durability of lens coatings (the anti-reflective coating, for example). Extreme temperature fluctuations could lead to surface cracks due to the different structures of the base lens and the coating.
Therefore, neither your case nor your spectacles should be left for long periods in a sauna or on your car dashboard in the summer.
HOW TO KEEP YOUR GLASSES CLEANER AND SCRATCH-FREE LONGER
Not only perfect lens care ensures optimum vision but also, of course, the lens itself. Special lens coatings with a hard protective layer and a beading effect (like DuraVision® Platinum from ZEISS) make your lenses extremely resistant to scratching and help guarantee that dirt, scratch dust and moisture can only adhere to the surface with great difficulty.
The benefit: your lenses remain dirt-free for longer, ensuring that they're significantly easier to clean. This means you also need less time to care for your lenses - and they will have a longer service life.
