Before discussing how to clean your glasses, we should look at a few basic
tips on keeping your lenses from getting dirty. Dust and dirt on your lenses
can hinder your vision and possibly scratch your lens if you aren't careful, so
you want to keep your glasses as clean as possible.
When you are taking your glasses on and off, hold them carefully with both
hands at the temples about midway down the sides. Don't grab them by the
lenses, as this will get grease and oil on them. Grabbing them with both hands
will also protect the adjustment to make sure your glasses fit properly. When
you aren't wearing your glasses, make sure to keep them in their protective
case. This will prevent dust and dirt from getting on them, and will also
protect them from being damaged by being accidentally sat on. (Having sat on my
own glasses a couple of times, this is something you would rather not have
happen). I have two separate cases, so I keep a spare in my car in case I want
to take them off or I lose my other case (hopefully not with my glasses in
them!)
Cleaning Your Lenses
Before cleaning your lenses you are going to want to make sure that you have
a proper cloth. I know the temptation to just wipe them on your t-shirt is
strong, but using worn clothing can damage the lens and you don't want this to
happen. You'll want to find the softest, most non-abrasive cloth you can find.
This'll make sure you don't accidentally damage your glasses while you are
trying to take care of them. Keep a nice soft clean cloth with you wherever you
go so you won't have to resort to the wiping them on your shirt routine if they
get dirty during the day and you want to give them a wipe.
Before wiping them, though, you'll want to make sure to rinse your glasses
with warm water. Even using a soft cloth on dry lenses can grind dirt into the
lens causing damage, and this is the last thing you want to happen. The warm
water will get rid of most of the dirt and grime, and make it easier for the
rest of it to come off. After rinsing, wipe the lenses thoroughly then put them
on or put them away.
