Avoiding The Scratches
We all wish there were “scratch-proof”
eyeglass lenses, but there aren’t. The plain truth is that plastic lenses
scratch. Scratched lenses are the one of the most common reasons why
people want an eye examination.
Glass lenses, are very scratch resistant, but are usually not dispensed
much due to them being much heavier than plastic lenses. Glass lenses do
“pit” with hot welding fragments. If glass lenses break, they break into
sharp glass splinters, increasing the likelihood of eye injuries. Plastic
lenses, on the other hand, break into blunt blocks of plastic. Eyecare
professionals do not generally recommend glass lenses anymore due to this
reason.
First of all, “scratch coatings” on plastic lenses are a layer over the
lens to reduce the likelihood of scratches… it does not make the “scratch
proof.” And, some lenses are only scratch coated on the front surface of
the lens and not the back. So ask your eyecare professional which type
they use. Scratch resistant coatings are what they are… scratch resistant.
What is the best way to avoid scratching your plastic lenses?
● ALWAYS rinse your lenses under warm running
water BEFORE you wipe them with a cloth. If you don’t, rubbing your dry
lenses just grind the dirt, dust and debris that is on the lens into the
lens… creating scratches.
● Never use a paper product to wipe your
lenses, like a paper towel or. All paper products are abrasive and they,
in themselves, can create scratches.
● Always use a clean, cotton cloth to wipe
your lenses (or a cloth provided by your eyecare professional). Do not use
your shirt.
The Bottom Line: Taking a bit more
time and care when cleaning your plastic eyeglass lenses will help ensure
that they will scratch less over time. ~RQ
