Eyewear Care
Cleaning your glasses
For a quick clean, a soft lint-free cloth is all you need. For anything more stubborn, warm water and a small drop of washing up liquid works well. Rinse and dry gently with a soft cloth.
Avoid paper towels, tissues, and clothing. They are rougher than they look and will scratch the lenses over time. Avoid alcohol-based cleaners and anything containing solvents, as these can strip lens coatings.
Keeping your screws tight
The small screws in the hinges of your glasses can loosen over time with regular use. If your arms start to feel loose, a small precision screwdriver is all you need. The tiny ones that fall out of Christmas crackers are actually perfect for the job. A gentle turn is usually enough. Do not overtighten or you risk stripping the thread.
Temperature and storage
Avoid leaving your glasses somewhere hot for long periods, a parked car, a sunny windowsill, or near a radiator or fire can all get hot enough to warp frames and damage lens coatings. The same applies for cold, an unheated car or garage overnight can make the plastic brittle too. Either way, it builds up over time: repeated bursts of heat, sun or cold, even short ones, can weaken the plastic gradually, so a frame can crack later with no obvious cause. If you're leaving a pair in the car, the glove box is a much better spot than the dashboard or a seat.
When you are not wearing them, keep your glasses somewhere they will not get sat on or scratched. A pouch or hard case if you have one, or just somewhere safe.
