Having your grasses, googles or any other piece of equipment fog up can be quite annoying. Not only that, your vision can be impaired resulting in an injury!

For this reason, we’ve decided to cover this topic today; we wanted to give you a better understanding of why the fogging even occurs, what can you do about it, how to prevent it and, of course, what is the best anti-fog spray you can use to clear your lenses!

Why Do My Glasses Fog Up

Your glasses fog up due to water condensation. As we exhale, water vapor comes out of our mouth and comes in contact with the lenses. Lenses then cool down this vapor and turn it into a liquid that fogs them up.

Other sources of hot vater vapor are:

  • Sweat from your forehead
  • Hot coffee you are drinking
  • A meal being cooked on the hot stove
  • Opening warm oven or a dishwasher
  • Phase Transition

    Watr condensation is a part of the process called phase transition. Phase transition is a process where a substance (in our case, water) changes from solid, liquid, or gas state into a different state.

    This change occurs as a result of a change in temperature.

    If we take our “glasses fogging up” as an example, it looks like this:
    – In the winter, the cold air outside will cool down your lenses
    – The temperature of your breath is relatively high (approx 35.5oC – 95.9oF) compared to the temperature outside
    – When we exhale our breath comes in contact with the lenses which cool it down and cause it to shift from a gas to liquid form
    – Resulting in fog appearing on your glasses

    How Can You Keep Your Glasses From Fogging Up?

    Keeping your glasses and goggles for free can be challenging during those winter months but here are 10 actionable tips you can try:

    1. Use anti-fog wipes
    2. Use anti-fog spray
    3. Apply shaving foam
    4. Use a bar of soap
    5. Use glasses that sit far away from your face
    6. Use water repellent spray
    7. Buy anti-fog glasses/lens
    8. Use contact lenses
    9. Use your saliva
    10. Taking them off

    Using Saliva, Anti-Fog Wipes/Lens, Or A Spray

    If you are wearing glasses, you should prepare yourself for winter. Buying a pack of good anti-fog wipes(or a spray) is a cheap, quick fix if you are not looking to spend a lot of money.

    And if you are dirt cheap, you can also use your saliva or your breath. Spitting directly on your glasses is, fortunately, entirely unnecessary. You can just put some saliva on your finger, rub it across the lens and use a wipe(or your shirt) to wipe it all off.

    The best solution to this problem would be to invest in a solid pair of glasses with an anti-fog lens. Investing in a new pair of glasses may require a bit more money, but it will take care of your problem permanently.

    Using Shaving Cream Or A Bar Of Soap

    Shaving cream is a quick fix that has been around for as long as I can remember. What you need to do is just to use a tiny dab of shaving cream and smear it across the lens.

    Let it dry out and then polish it, using a clean cotton cloth. The end result will be impressive and it will last for some time.

    Applying soap is pretty much the same.

    Using A Water Repellent Spray

    Making your lens water resistant by using a water repellent spray is another effective way of preventing them from fogging up.

    The only problem is, anti-fog sprays for glasses are relatively small in size, so you can carry them with you wherever you go; this is not the case with water repellent sprays, which are usually larger.

    Taking Your Glasses Off/Keeping Them Away From You Face

    Choosing a pair of glasses that will sit further away from your face can take care of the fogging up problem(if it was caused by your breath).

    Also, removing them from your face and storing them your pocket for a couple of minutes, will warm the lenses up and may prevent that phase change we talked about earlier.

    Best Anti-Fog Sprays In 2018

    We have to say that, during our research, none of the products really “popped.” There were only a few that we found to be promising, which we will mention in the following paragraphs.

    That being said, our top advice would be to invest in a pair of anti-fog glasses/goggles. You can find some good deals on Amazon by clicking here.

    Another route you can take is to buy wipes. You can find them here.

    And now, for the sprays. Here is our selection:

    Jaws Quick Spit Antifog Spray

    This one proved to be the best one we’ve come across(it is also Amazon.com’s top choice), it is long lasting (approx 200 pumps), contains no toxic chemicals and it will work for both glass and plastic.

    Now, these sprays are mostly for your everyday, regular use. Though they are advertised to be used in water as well, they have not performed the best.

    You can always give them a go, they are relatively cheap, won’t put a dent in your budget, and will help you keep your lens clean.

    Jaws Antifog Gel

    You’ve noticed this product is made by the same company as the previous one.

    It also contains no harmful chemicals and is meant for both glass and plastic.

    The only difference we’ve noticed so far was the fact this product works better in water than the previous one. Though there is a disclaimer saying “It is not meant for water goggles,” it performs well in the water environment.

    Scuba Mask Sea Drops

    This product is more geared to divers and those individuals who want to coat their goggles, though you can use it for your glasses as well.

    It is formulated to be alcohol and toxic so it won’t damage plastic or rubber parts of your equipment.

    It is made in the US and it comes in a package of three bottles, so it will have you covered for months to come.

    Cressi Antifog

    If you take a look at their product page, you will see that Cressi is offering three different choices:

    • A spray
    • Wipes and
    • Drops

    You can choose yourself, but we found that spray offered the most “bang for the buck” as it will outlast the other two.

    Though this product is advertised only for glasses and scopes, you can just as well use it for your goggles. Just make sure you rub it on the inside of the lens prior to wetting them.
