[2022] Daily maintenance for glasses/sunglasses

Hello, I'm OKD from METRONOME-Tokyo Online, the official Japanese online store for METRONOME DESIGN INC., which sells METRONOME®, an eyewear brand that started in London.
This time, I would like to talk about the daily maintenance of eyeglass/sunglasses frames. These are simple things that can be done on a daily basis, so for more serious adjustments and maintenance, I recommend going to an optical store or other specialist store.
Lens screw tightening
Well, speaking of daily maintenance, isn't it just tightening the screws? The metal fittings that control the opening of the temples are tightened with screws, but they will become loose with continued use.
As long as the screw holes are aligned, you can use a regular tool (screwdriver). There are Phillips and Flathead screwdrivers, so please check the frame. Also, if your lens flips up, you can tighten the screw to remove any looseness.
There seem to be many similar drivers available for purchase online, so why not get one at the same time as you purchase your glasses/sunglasses?
Lens maintenance
Of course, lens maintenance is also important. It's also important to wipe them off as soon as possible when they get wet. Make good use of eyeglass cleaning cloths (cleaning wipes). It has also been pointed out that viruses and bacteria can adhere to eyeglass/sunglasses lenses.
It is important to keep your eyeglass/sunglasses frames clean on a daily basis using an ultrasonic cleaner or cleaner. I usually use an ultrasonic cleaner. There are also many cleaners available on the market. Spray types containing alcohol are easy to use.
summary
Of course, this type of maintenance can also be carried out at an optical store, so if you have a favorite shop nearby, it would be best to use it.
Personally, I like to do as much as I can myself, so I have my own screw tightening tools and sonic cleaner. Neither of these are very expensive and are easily available.
Please consider it.
