Hello and welcome to the TranslatorsCafe.com Channel!
In this video I am going to explain how to clean your eyeglasses or sunglasses with or
without anti-reflecting and oleophobic coating.
Many people clear lenses of their glasses like this: they exhale onto their lenses and
then wipe the fog off with a dirty piece of cloth.
In a couple of months their plastic lenses are damaged and much to the joy of opticians
they order a new pair of glasses in less than a year.
When 10 years ago I started wearing reading glasses every day, I did not know how to clean
them.
I saw many products for cleaning and even tried several of them until I found the best
way to clean my eyeglasses without scratching them — to wash them.
It should be noted that when I made a research before starting making this video, I realized
that the idea is not new and that many people clean their glasses this way!
The first thing: never ever dry your lenses with paper towels, which contain wood fibers
that can scratch your lenses.
Also, never use even 100% cotton material, which can also be filled with dust, which
contain abrasive particles.
Although you can use special cleaning solutions, don’t do it if you don’t want to waste
your money.
The cost of water, drop of isopropyl alcohol and a drop of dishwashing liquid is almost
zero comparing to the cost of cleaning solutions.
Just wash away dust from your lenses with warm water.
Then apply dishwashing liquid to both sides of the lens and rub them gently.
Rinse with tap water, then do a final rinse with distilled water.
The distilled water is necessary if your tap water is hard.
Dry then with an air blower or with a compressed gas duster.
Your lenses will be clear and clean with no scratches.
So, here are the steps: Wash your hands to remove grease from your
fingers.
Rinse your eyeglasses with warm water to wash away dust from your lenses.
Put just a little bit of dish soap between your fingers.
Dish soap is designed to remove oily and greasy residue from your dishes.
This is what you want to do to your glasses!
You want to remove grease!
Apply the soap thoroughly with your fingers in circular motions on both sides of the lenses.
You can also continue applying the soap onto the rest of the frame, including the temples,
bridge and nose pieces.
Rinse your glasses under warm water, which will remove the soap.
Do not use your fingers while rinsing.
If your tap water is hard, that is, it contains dissolved minerals of calcium and magnesium,
then you will need to rinse your glasses in the distilled water.
After rinsing, shake or tap your glasses against your knee to remove water drops.
Now use an air blower or compressed gas duster and blow all water that remained after tapping.
If you used distilled water, blowing is not necessary.
Water will dry without any traces of salts on the glass.
All glasses and sunglasses often come with a little cloth.
Opticians put this little cloth with one reason: they want you to come to them more often!
Any cloth and especially paper towels and any other paper products will scratch your
lenses because they contain abrasive particles.
Besides, cloth and paper usually just smear dirt all over the lenses.
When you use the compressed gas blower, press its trigger gently because it can “spit”
liquid in the gas stream.
If this happens, you will have to repeat cleaning with soap and water.
You can wipe any residual water only from lens edges.
A note about alcohol.
Some people say alcohol can remove lens coatings and leave a fogged lens.
I used isopropyl alcohol to clean particular greasy lenses and never
noticed any problem.
Isopropyl alcohol is also used in commercially available pre-moistened lens cloth.
The same technique can be used to clean camera lens filters used when taking pictures with
a DSLR camera.
Wash them with dishwashing detergent, then rinse with running water, and then do a final
rinse with distilled water.
After that blow off all drops with an air blower.
Unfortunately, this technique cannot be used to clean the front elements of your lenses.
