What To Look For When Buying a Mask Anti-Fog Solution A scuba mask anti-fog treatment is truly a worthy investment. Some divers might argue that you can just substitute it with your own spit or baby shampoo, but the former is a little gross and the latter doesn’t always work. There are also anti-fog solutions that can double as a cleaner for your scuba mask, so you are cleaning and defogging at the same time. But to make sure that you’re buying the best mask anti-fog here are our top tips to keep in mind when choosing: Check the consistency. The consistency of the mask anti-fog is actually quite important when it comes to gauging how helpful and effective it can be. If it is too thin, it might not cling to the mask that well so won’t last very long. But if it’s too thick it can be a hassle to apply. Usually, the ones with a thicker and gel-like consistency work longer and more effectively because they hold to the surface of the scuba mask better. However, they will require you to properly smear and rub the formula across the lens. If you prefer something that’s super quick and easy to apply, opt for a thinner formula in a spray bottle. Make sure it does not contain alcohol or any other ingredients that can harm the eyes. Since you will be placing it so close to your eyes, make sure it doesn’t contain ingredients that can damage or irritate your eyes. Alcohol-based formulas can emit fumes that sting the eyes. Always go for those scuba mask anti-fog that are safe to use. It should also be safe for the environment. As you know, the marine environment is very sensitive to chemicals and unfortunately, some products contain toxic ingredients that are harmful, or even deadly, to marine life. The product you are putting on your scuba mask could leak chemicals into the ocean, which can have devastating effects on our coral reefs. Make sure you look for an anti-fog that is reef safe and doesn’t contain any harmful chemicals so we can help preserve the marine environment. It should also be able to keep your mask clean. Many of the best mask anti-fog treatments have a 2-in-1 formulation. So they can be used both as a defogger and a cleanser. If you want to save more money and time, a 2-in-1 formula is a perfect choice. Find out if you can use it for other types of eyewear. Not all of the scuba mask anti-fog solutions can be used for swimming goggles. If you want a more versatile product, make sure you choose one that’s suitable for use on all eyewear. Look for the best deals Consider a package deal where you can buy 2 or more bottles for a discounted rate. If you plan on doing a lot of scuba diving or want to use the anti-fog treatment for other activities, this will help you save money in the long run. You could also gift your dive buddy a bottle, we’re sure they’d love it! What’s Next? Once you start using a mask anti-fog treatment, you’ll be surprised at how you ever went diving without one. The best anti-fog solutions ensure that you’ll never miss out on any of the underwater magic again! Do you use an anti-fog solution for your snorkel or scuba mask?
