Whether you wear eyeglasses for fashion reasons or to see properly, chances are, you've found a way to comfortably and aesthetically fit them into your daily lifestyle. However, there's now a need for wearing face masks to help slow the spread of COVID-19 (Coronavirus). So, like a responsible citizen, you wear your mask but are then rewarded with totally fogged-up glasses. So, you ask, “What’s the deal with my glasses fogging up when I wear a mask?”

We’ve got that answer, along with tips to keep your eyeglasses clean and fog-free — even while wearing a mask.

Why Do Eyeglasses Fog When Wearing a Mask?

Airflow and body heat can cause eyeglass lenses to fog. When warm air comes in contact with a cool surface, condensation may form. Have you ever walked into a warm building after being outside in the cold, and your eyeglasses became foggy? The same thing can happen when wearing a mask. When you wear a mask, you're breathing out warm air repeatedly. This air then sneaks out of your mask at the top and steams up your glasses.

And there’s proof: The Annals of The Royal College of Surgeons of England published a study that showed masks actually direct much of your exhaled air upward. Technically speaking, eyeglass lens "misting" occurs when your breath's warm water vapor lands on your cooler lenses and produces tiny droplets, which scatter light and reduces the ability of your lenses to transmit contrast (dark colors stay dark and light colors stay light). According to the study’s authors, these droplets form due to the inherent surface tension of the water molecules.

For most people, this eyeglass fogging is quite a nuisance. And, because there are nearly 200 million adult vision correction users in the U.S., according to The Vision Council, that’s a lot of eyeglass fogging going on — and annoyed spectacles wearers in the process. But, once you gain an understanding of the reason why eyeglass fogging occurs, solving the problem is more attainable.

How to Keep Eyeglasses Clean While Wearing a Face Mask

Here are ways on how to keep your eyeglasses clean while you're wearing a mask.

1. Use Soap and Water

Soap and water might sound like the most simple way to keep your eyeglasses clean, but you'd be surprised how many other "no-no's" people turn to when trying to clean their glasses. The steps of basic cleaning of your eyeglasses with soap and water, which provides a thin surfactant film, are:

• Run your eyeglasses under cold water.
• Rub the lenses lightly with a mild dishwashing liquid soap.
• Rinse your eyeglasses lightly under a stream of water.
• Dry your eyeglasses off carefully with a soft lens cloth (ideally a lint-free, microfiber cloth).

2. Ensure Your Mask Fits Well

If your mask is loose-fitting, it directs your exhaled air toward your eyeglasses. However, if your mask fits snugly, it directs the air out the sides or bottom of your mask instead, away from your eyeglasses.

3. Mold the Mask to Your Nose

You should:

• Mold the mask to your nose by adjusting the bendable metal strips, which reduce the flow of air through the top of your mask.
• Consider adding a metal twist tie or pipe cleaner to create a similar effect if the mask you're using doesn't have a bendable metal strip or it's homemade.
• Pull your mask up with your eyeglasses sitting on top of it to hold it against and across the bridge of your nose. The weight of the eyeglasses will help block the flow of air from being directed out the top of your mask.

4. Seal Your Mask

One common trick doctors employ is to stick a strip of double-sided tape across the bridge of their nose before putting their mask on. If you add a double-sided tape strip between the bridge of your nose and the inside of your mask, it creates a better seal.

Or, you could also place an extra piece of masking tape or cellophane over your mask too. Some doctors swear by applying a bandage to the top of the mask and the nose.

5. Place a Tissue Inside the Top of the Mask

Horizontally fold the tissue and place it between the top of your mask and your face, so it sits just over the bridge of your nose. The theory here is the tissue will absorb the moisture from your breath rather than hitting your glasses.

6. Adjust Your Eyeglasses

Adjusting your glasses, while obvious, is a great solution as it adjusts where your eyeglasses sit on your nose. Pushing your glasses up forward on your nose allows increased airflow, which can help with fogging. You can also try resting your eyeglasses over the top of your mask, creating a tighter seal.

Products That Can Help Keep Your Glasses Cleaner for Longer

There are commercial cleaners and anti-fog products you can try for keeping glasses clean when wearing a face mask. Here are a few examples:

1. Castile Soap

Liquid castile soap is a highly versatile, gently formulated cleaning essential made with sensitive skin in mind. It's less astringent and effective for just about any cleaning purpose.

2. Mrs. Meyer's Clean Day Rain Water Hand Soap

This is hand soap made with aloe vera, olive oil, essential oils, and other ingredients with no phthalates, parabens, or artificial colors.

3. Z Clear Lens Cleaner & Anti-Fog Spray

This is an anti-fog spray for preventing fog. It's 100% ammonia and alcohol-free, safe on anti-reflective coated lenses, and made safe for all types of prescription eyeglasses.

Be sure you read all instructions on any product you decide to use since each product will be different. Always read the fine print as some anti-fog products could cause damage to lens coatings, such as their anti-glare coating. Some sprays and wipes may cause skin sensitivities as well.

4. MotoSolutions FogTech DX Anti-Fog Wipes

Available in packets of 1, 5, 12, 20, and 100, these anti-fog wipes are popular among snowboarders, skiers, motorcycle riders, welders, and more.

Some “Don’ts” When Cleaning Your Eyeglasses

• Do not clean with your spit. Saliva is, well, unhygienic. Given COVID-19 is a respiratory virus, and we’re trying to stop its spread, spitting on your glasses isn’t recommended at this time.
• Do not use harsh chemicals. Harsh chemicals found in products like window glass cleaners, for example, can damage the coatings on your lenses.
• Do not use toothpaste. Some toothpaste has grainy substances, such as baking soda, mixed in. These can cause abrasions or scratches on your lenses, making it more difficult to see.
• Do not use baby shampoo. You may think that baby shampoo is gentle and perfectly safe to use to clean your eyeglasses. However, we do not recommend using it because it could create a residue or film that inhibits your vision.
• Do not use vinegar. Vinegar is highly acidic, which could strip away the coating on your lenses.
• Do not dry with a fabric exposed to dryer sheets or fabric softener. These can leave a residue on your glasses.

ACA. ACO. CDHP. COB. EAP. 

OMG. There is no shortage of acronyms when it comes to health insurance.  Even the people who work in health insurance have to sometimes refer to their handy pocket glossary.

Instead of letting it all stress you out, let’s take a moment to appreciate one very special acronym that is actually incredibly important and beneficial to you – HSA.  Or Health Savings Account. 

But what is it, and why should you use it to your advantage?

Getting to know the HSA

Most people know the basic definition of an HSA.  It’s a savings account that you contribute to with pre-tax dollars, and can use to pay for qualifying medical expenses.  Most people deposit money onto their HSA on a bi-weekly or monthly basis, right out of their paycheck. The dedicated funds go right into their HSA, instead of to their bank accounts.

In order to sign up for an HSA, you must be enrolled in an HSA-qualified high-deductible health insurance policy (HDHP).  This typically means that you pay a lower premium (payment) for your insurance coverage on a bi-weekly or monthly basis, but are subject to a higher amount you must pay out of pocket (your deductible) before your insurance kicks in.  Most high-deductible plans only cover preventive care until you meet your deductible.

Contribution limits

The 2020 contribution limits for HSAs are $3,550 if you have individual coverage, and $7,100 if you have family coverage under an HDHP.  HSA-qualified plans (HDHPs) have deductibles that must be at least $1,400 for singles and $2,800 for families in 2020.

Did you know….

…an HSA is interest-bearing, and grows over time

If you don’t spend all the money in your HSA, your funds roll over into the next year, and your account continues to grow, including any investment returns or interest. 

…HSAs don’t expire

This is important to repeat, because many people assume if they don’t use it, they lose it.  This is not true – HSA funds roll over from year to year, and your account continues to grow.  Don’t lose those old benefit documents!

…most states offer extra tax breaks

With the exception of California, Alabama, and New Jersey, most states offer extra tax breaks on the contributions you make to your HSA.  In addition, HSAs are tax exempt for purposes of your federal income tax filings, and are also tax exempt for most state income tax filings.

Even better, many employers make a contribution to your HSA at the beginning of the year to get you started.  And if an employer contributes, the money is not taxed as income to you.  Make sure you check your benefit options carefully when it’s time for Open Enrollment.

…you can use it for yourself, or others

You can use your funds to pay for your own medical expenses, or those of a spouse or other family member even if they aren’t covered by your HDHP.  Family members include dependent children or qualifying relatives, as long as they’re a part of your tax household.

…you can contribute more if you’re 55+

If you’re 55 or older, you can contribute an extra $1,000 a year (this is either called an “additional contribution” or a “catch-up contribution”).  If two spouses are each 55+, please note that they each need their own HSA in order to be able to each make a catch-up contribution.

…the rules change after Medicare

Once you’re enrolled in Medicare, you can no longer contribute to an HSA (even if you continue to work and have an HDHP plan through an employer). However, you can continue to withdraw tax-free funds from your HSA, as long as you use the money to cover qualifying medical expenses, including Medicare premiums.

Listen, this is all amazing. But what medical expenses qualify?

Medical expenses can include deductibles, copayments, coinsurance, vision and dental care, and other out-of-pocket medical costs. 

Awesome!  What else can you use an HSA for?

Many people are surprised to learn you can use your HSA to pay for things like acupuncture, chiropractor services, hearing aids, home care, breast pumps, pregnancy tests, and yes, eyeglasses!

The lens material known today as “Trivex” has a really interesting history. Its scientific roots are heavily embedded in the United States military, with applications ranging from helicopter windshields, transparent body armor, and fighter jet canopies. It wasn’t long before these scientists realized that the extreme impact resistance coupled with its fantastic optical clarity and ultra-lightweight properties would make it a best-selling optical lens.

So that’s great, but why should you choose Trivex lenses when picking out your next set of eyeglasses? Why not go with a polycarbonate lens instead?

There are a lot of reasons why Trivex lenses are some of the best eyeglass lenses, including their use to provide eye safety and protection. At Replacement Lens Express, we love the history of these lenses and proudly offer our Trivex lenses online. Start protecting your eyes with some of the best eyeglass lenses today.

Strong and Safe

Trivex lens material is incredibly impact resistant, sometimes being referred to as “shatterproof.” In fact, when the lens was originally designed, Trivex was subjected to rigorous ballistic and extreme performance testing to ensure the durability of the lens. As a result, Trivex lenses are ideal for athletes, safety-glass wearers, and children, who all benefit from their strength and safety.

Great Tint

Trivex lenses tint better than traditional polycarbonate lens material. So if you’re thinking about designing an interesting pink-to-clear gradient fade, or a more traditional grey sunglass lens, Trivex would be a better, more easily customizable choice here. You can learn more about our tinting process in our help guide.

Versatile Lenses

When working with rimless frames, our opticians love Trivex lenses because they are easier to drill and the material is resistant to cracking around the drill holes. This makes Trivex lenses a sturdy, versatile choice for any frame.

UV Eye Protection

Trivex lenses provide 100 percent protection from the sun’s harmful rays, protecting your vision and overall eye health. So put away your wallet and save some money here, as you won’t need to add a UV-coating to these lenses!

Light, Thin Lenses

Trivex lenses are thinner and lighter than traditional plastic lens material. In fact, they are 10 percent lighter than polycarbonate lenses.

Clear Optics

Trivex lenses have crisper, clearer optics than their injected-molded cousin, the polycarbonate lens. This helps make Trivex lenses some of the best eyeglass lenses, especially if clarity is a feature you need in your lenses.

Replacement Lens Express

The benefits of Trivex lenses make them some of the best eyeglass lenses when you’re ready for replacement lenses. Other lenses, like polycarbonate, might have a higher refractive index, but Trivex lenses have other qualities that make them a great choice when you’re looking for safety lenses to help protect your eyes.

At Replacement Lens Express, we have a wide assortment of lenses online. If you need an updated prescription but still love your old frames, let our team replace your lenses so you can keep the frames you love. Shop our collection of Trivex lenses online today!

When choosing between a standard sunglass lens and a polarized lens, consider the extra protection that polarized lenses offer your eyes when designing your next pair of sunglass lenses.

The technology behind polarized lenses is just as interesting as the reasons for choosing these lenses in the first place. Polarized lenses were first invented by NASA scientists to help protect astronaut’s eyes when they went up into space. These scientists studied the design of an eagle’s eye to understand how they reflected glare, giving the glasses the original name of Eagle Eye Sunglasses.

This NASA technology has been adapted for lenses to help protect your eyes. Polarized filters are put over the lenses that work to absorb light reflected off of horizontal surfaces. This horizontal light, also known as glare, is dangerous for the long term health of your eye. This polarized filter helps you see better when you’re driving or working somewhere with direct sunlight.

From a technical perspective, the polarized filters create an opening that only allows vertical light rays (not the horizontal light waves reflected off surface) to get through. This filtration blocks out any potential glare, allowing you to see clearly when normal glasses would give you a glare.

The polarized lens technology is an easy choice if you’re looking for less glare and more protection with your new lenses. You can shop our polarized lenses online at Replacement Lens Express.

WHY CHOOSE POLARIZED LENSES? 

While NASA technology in your sunglasses sounds awesome, there are also some great reasons to choose polarized lenses when you build your new lenses on our website!  

They are better for your eyes.

Polarized lenses protect your eyes from dangerous UV rays. For the same reason you’re not supposed to stare directly at the sun, UV rays are harmful for your eyes. Constant exposure to UV rays can cause macular degeneration, vision loss, and other eye problems later in life. Cutting down the amount of exposure your eyes have to these UV rays will help keep your eyes healthy and strong.

With polarized lenses, you don’t need to add an extra UV coating to your sunglasses. Instead, this UV protection is an added benefit of choosing polarized lenses.

Filters Blue Light

The filtration on polarized lenses also blocks blue light, a wavelength that works to keep us awake and alert throughout the day. Most of our exposure to blue light comes from staring at computer and phone screens, but at night, the blue light can disrupt your circadian rhythm. To help balance your circadian rhythm, researchers are recommending filtering out blue light at night (or reducing screen time).

While other lenses, like our clear EyeZen technology, can help reduce eye strain and protect your eyes when you’re inside or staring at a computer screen, polarized lenses will reduce your exposure to blue light when you’re outside.

Reduces Glare

The polarized lenses prevent intense sunlight rays from getting to your eyes, eliminating glare when you’re outside. This glare reduction keeps you safe while driving during the day and keeps your eyes on the road.

Whether you are a morning commuter, athlete, or outdoor enthusiast, the glare reduction provided by polarized lenses will give you the best advantage regardless of what activity you’re doing. But if you wear eyeglasses more than sunglasses, anti-glare coatings like the Crizal SunShield can also give you the same protection from glare with your eyeglasses.

Enhances colors

When compared to non-polarized lenses, polarized lenses can make everything look darker. However, this filtration and lack of glare can also make those objects look clearer because your eye no longer sees those horizontal light reflections.  

But by filtering out the glare, colors look more vibrant and objects look more clear. With your polarized lenses, you’ll always have a breathtaking view with no glare blocking your vision.

They come in a variety of colors

When you add polarized lenses to your sunglasses, you can choose from a variety of different colors. From the more traditional brown, grey, or green, to more vibrant colors like copper, amber, sunflower, rose, and ocean, you can pick a color that makes a bold statement and matches your favorite frames.

WHY POLARIZED LENSES OVER TINTED LENSES? 

When you’re choosing lenses for your sunglasses, it can be hard to choose between polarized or tinted lenses.

Tinted sunglasses help with different things, depending on the tint of the glasses. For example, yellow tints can increase visibility with fog while darker tints can help motorcyclists and commuters filter out sunlight during long drives.

As we mentioned earlier, the technology behind polarized lenses blocks all horizontal light reflected off surfaces. This is handy for someone who doesn’t need to see those reflections and wants to protect their eyes.

What to see what this means? Here’s a test you can do to both verify that a frame has polarized lenses and better understand the technology for yourself.

1. Take two pairs of sunglasses with polarized lenses
2. Holding both pairs out, tilt one pair to a 90-degree angle.
3. Overlap the lenses on both sunglasses

When these lenses are overlapped, you should see black. This is because you’ve inverted the horizontal technology so you are now blocking out all glare from light.

When you do this same test with tinted sunglasses, you won’t get the same effect. But tinted lenses are better for someone who doesn’t want to filter out intense sunlight, including pilots and skiers who need the light to perform.

Tinted and polarized lenses provide different kinds of options for your sunglasses. But with eye protection, blue light and glare filtration, color enhancement, and color options, polarized lenses offer many improvements for your eyeglass experience.

THE NEED

Here’s a shocker: staring at screens all day long is unavoidable these days. All that screen time is hard on your eyes and could cause digital eye strain. This is true even if you don't wear glasses.
