Are Anti Fog Lenses Worth It

If you wear glasses, you know how annoying it is when they fog up, making it impossible to see where you’re going or what you’re doing.  This problem has become even more relevant in the last year, with masks making it even more likely than ever for your glasses to fog.  Couple that with colder temperatures over the last few months, and you’ve got a recipe for foggy lenses.  So, what can you do about it?

There are a few things you can do to prevent your current lenses from fogging.  Anti fog sprays and wipes are available that can temporarily stop your lenses from fogging, but they usually only last a few hours, meaning you have to remember to reapply if you want those lenses to stay fog-free.  Another problem with these products is their cost.  Even though each pack of wipes or bottle of spray is relatively cheap, the cost adds up as you keep reapplying, running out of a product, and buying more anti fog for glasses. 


What Are Anti Fog Lenses?

The other solution to the foggy glasses problem is to buy anti fog lenses.  These are lenses specifically made so that they will never fog up.  In addition to being easier to use (you don’t have to keep reapplying products to your glasses), they are ultimately a cheaper option than buying other anti fog products.  Rather than buying a pack of wipes for somewhere between ten and twenty dollars every few months, investing a little more money upfront means you get a pair of anti fog lenses that can last years without ever fogging up.

Anti fog lenses are made never to fog up.  The anti fog lenses found on don’t use any coating that can wear out, meaning you’ll never have to worry about applying or reapplying some spray or wipe every time it starts to wear out.  These lenses pay for themselves the longer you have them, but they’re also just much more convenient than other forms of anti fog for glasses.  If you make these lenses your new daily drivers, you’ll never have to worry about your lenses fogging again.

Most sprays and wipes need to be reapplied at some point over the life of the glasses.  Even the longest-lasting sprays only stay on for about a month, but most only last around 24 hours.  That means if you forget to reapply before putting your mask on and going to the grocery store, your glasses will fog before you make it through the produce.  The anti fog used in lenses designed with this in mind never wears out, so you’ll never have to apply a spray or worry about the anti fog not working ever again. 


How Do Anti Fog Lenses Work?

In order to talk about how these lenses work, we first need to know what causes glasses to fog in the first place.  Glasses fog up because of water condensing on the surface of the lens.  A number of different things can cause this, but temperature, humidity, or even physical activity can all play a role in how quickly your lenses fog up.

When water from sweat, breath, or just humidity in the air condenses onto your glasses, you experience a foggy lens.  Now that masks are mandatory in most public settings around the world, your breath is being directed straight up through your mask and onto your glasses, where water vapor from your breath condenses and fogs up your lenses.  In cold weather, this water vapor can freeze, causing even more problems. 

Anti fog for glasses works using chemicals that prevent water from condensing in tiny droplets.  Fog on glasses is actually just a lot of tiny droplets of water, so most of these anti fogging agents work by making sure these tiny droplets are unable to stick to the surface of the glasses.  Some anti fogging agents are better than others, and most will fog if the humidity is high enough, but all are much better than standard lenses.

NASA actually developed Anti fogging agents in the 1960s to prevent astronauts’ visors from fogging up while they were out in space.  After NASA developed their first space suit, they found that the visor would fog up incredibly quickly.  They developed technology that made it incredibly difficult for tiny water droplets to form inside the visor, which is the same technology being used in eyeglass lenses.  After 1966, all of NASA’s helmets have been treated with anti fogging agents. 


Where Can I Find Anti Fog Lenses?

There are lots of places to find anti fog for glasses online, but makes it as easy as possible to get you a prescription, anti fog lenses for a reasonable price.  They start at just $59, meaning these lenses are the equivalent of buying only three boxes worth of anti fog wipes.  And you would certainly go through that many in a few years of trying to get your glasses to stop fogging up.

Anti fog lenses on are currently only available for single vision prescriptions but can fit into most plastic, metal, and semi-rimless frames.  There is no coating that can wear off on these lenses, meaning they’re good for as long as your prescription stays the same.  You don’t need to add a coating to them every time you walk out the door, and they’re scratch-resistant, impact-resistant, and block 100% of UV light.  These lenses are designed to last as long as possible. 

All you need to do to get your own set of anti fog lenses is to take a picture of your prescription, upload a selfie so the experts at can get the measurements they need for your new lenses, and send in your frames if you want to keep them.  If you want a new set of frames for these special lenses, there are plenty of affordable options available so that your new go-to set of lenses is paired with a comfortable, stylish frame.
