Using the wet part of the cloth to gently wipe one side of the lens clean, and then the other. To finish the job, dry the lenses with the dry part of the microfiber cloth.

Cleaning your eyeglasses is a daily routine. While we’re often guilty of using whatever’s close by and handy to clean them, some habits may not be as useful as we think. To help you see clearly all day long, here’s a five-step guide on how to clean your glasses the right way.

Tired of cleaning your eyeglasses three times a day? Your relationship with your glasses is just like any other: You’ve got to give it some TLC for it to last!

Remember what your parents would tell you right before dinner? Well, the same goes for cleaning your glasses. Make your folks proud and start your cleaning ritual by washing your hands! Make sure to use cool or warm water with a little bit of mild dishwashing liquid or hand soap.

The inside (nasal) edge of the eyeglass lenses, where they meet the bridge of the frame, is a prime spot for collecting sweat and oil. Make sure to give this area some extra love. Also note that:

When nose pads go yellow, it’s time to replace them. Most nose pads are universal and can be obtained at any optical center.

Ensure that the tap water is lukewarm (hot water could damage the coating or warp your lenses). If you wouldn’t bathe a newborn in it, it’s too hot!

Using anything other than a proper eyeglasses cleaning cloth can cause micro-abrasions on your lenses.That will cause them to lose their sharp focus and become hazy over time. So remember, you might love your favorite item of clothing, but it doesn’t mean they make great eyeglass cleaners! Microfiber is the way to go.

The atomic-scale properties of lanthanum–strontium manganite (La1−xSrxMnO3−δ, LSMO) surfaces are of high interest because of the roles of the material as a prototypical complex oxide, in the fabrication of spintronic devices and in catalytic applications. This work combines pulsed laser deposition (PLD) with atomically resolved scanning tunneling microscopy (STM) and surface analysis techniques (low-energy electron diffraction – LEED, X-ray photoelectron spectroscopy – XPS, and low-energy He+ ion scattering – LEIS) to assess the atomic properties of La0.8Sr0.2MnO3(110) surfaces and their dependence on the surface composition. Epitaxial films with 130 nm thickness were grown on Nb-doped SrTiO3(110) and their near-surface stoichiometry was adjusted by depositing La and Mn in sub-monolayer amounts, quantified with a movable quartz-crystal microbalance. The resulting surfaces were equilibrated at 700 °C under 0.2 mbar O2, i.e., under conditions that bridge the gap between ultra-high vacuum and the operating conditions of high-temperature solid-oxide fuel cells, where LSMO is used as the cathode. The atomic details of various composition-related surface phases have been unveiled. The phases are characterized by distinct structural and electronic properties and vary in their ability to accommodate deposited cations.

For plastic frames without nose pads, make sure to clean the portion of the bridge in contact with your nose to remove built-up oil and sweat.

Store your glasses in their case when you’re not wearing them. Most of the dirt on your glasses comes from wearing them on your head!

Make sure to always clean your glasses when they’re wet, as cleaning a dry lens just increases the chances of the cloth simply dragging debris and smearing oil across the lens instead of picking it up.

Remove the majority of the water from the lenses and frame by patting dry. Use a dedicated microfiber cloth or a clean, fresh out–of–the–dryer cotton towel that hasn’t come into contact with fabric softener or dryer sheets. You want to ensure that there’s no debris that could scratch your lenses.

Another thing to avoid is thinking saliva will help your lenses – it won’t. It’s much more likely to be the spitting image of a disaster when it comes to cleaning your eyewear. In fact, you’ll effectively be doing the opposite of cleaning your glasses. While it may feel like a tempting solution because of its convenience, it’ll probably make your lenses look worse, not to mention the hygienic reasons why this isn’t a good idea (saliva = germs). Best stick with soap.

If you’ve been out during a hot day, make sure to rinse your glasses with cool water afterwards (not applicable on anti-fog lenses). Sunscreen, salt water, and other chemicals that dry on the lens can damage the coating over time.

Keep anti-fog lenses away from soap, running water, and harsh chemicals, such as acetone, and store them in a cool, dry place (like your glasses case!) when you’re not wearing them.

While you’re rinsing your hands, grab your glasses and give them a little rinse under a gentle stream of water. Dab a tiny amount of mild dishwashing liquid on both the front and back side of each lens. Rub both sides of your lenses for a minute and give the frame a little clean too — don’t forget the nose pads!

If you use bottled eyeglass cleaner, make sure that it’s labeled “safe for coated lenses” (not applicable on anti-fog lenses). Some brands may not be as appropriate for maintaining your glasses.

Knowing how to clean your glasses correctly can help them last longer and ensure that they perform the function they’re there for – keeping your vision crystal clear!

Don’t use anything containing alcohol. Not only can it damage the lenses themselves, but could also risk weakening some types of frames.

To keep them working effectively, anti-fog lenses should be wiped daily (only with your microfiber glasses cloth) and cleaned weekly.

Using an ultrasonic cleaning device can be an option for an in-depth cleansing of your glasses. You can find them in several optical stores.

You may notice small amounts of water working their way out of the hinges or the groove between the frame and lens. This is nothing to worry about and can be dabbed off with your lens cloth. The lenses may even “squeak” in the frames for a few hours until any remaining traces of water evaporate.

After patting dry, finish the lenses with the microfiber cloth and a little bit of moisture with either a commercially available lens cleaner labeled “safe for coated lenses” or simply breathe softly into each lens. Make sure the lenses aren’t dry when you’re cleaning them to prevent dirt or debris from being dragged across the surface.

If you have anti-fog lenses, avoid cleaning with soap and soaking or rinsing them under running water. Otherwise, their effectiveness will be reduced.
