How to keep your scuba mask clear

Scuba masks can fog up when the warm, moist air from a diver’s breath meets the cooler surface of the lens. They are the second most important piece of scuba equipment, right after your air and BCD (counting that all as one unit). Read on to learn tips on how to keep your scuba mask clear and help prevent fogging.

Pre-Dive Preparation

Before embarking on an exciting scuba diving adventure, it is crucial to ensure that your scuba mask is properly prepared. Whether you’re diving in Okinawa or enjoying some water adventures in Thailand, pre-dive preparation for your mask not only guarantees clear vision and a comfortable fit underwater but also enhances your overall diving experience. From inspection and cleaning to defogging techniques, we will explore the essential steps to take in order to ensure your scuba mask is in top-notch condition before each dive.

Choose a well-fitting mask:

When it comes to selecting a scuba mask, it is crucial to choose one that fits properly. A well-fitting mask not only ensures a clear view, but it also prevents leaks and discomfort. Make sure to try on different masks to find one that provides a secure, yet comfortable fit.

Pre-treat the mask with an anti-fog solution:

Most dive shops carry anti-fog solutions, which can help to prevent your scuba mask from fogging up during your dive. Apply the solution to the lens and rub it around with a finger or soft cloth until it is evenly distributed. Allow the solution to sit for a few minutes before rinsing it off with clean water.

Properly clean the mask before use:

Before you head out for a dive, it is essential to clean your scuba mask properly. This will ensure that any dirt, debris, or residue that may be on the lens is removed, providing a clear view. To clean your mask, use a mild dish soap and warm water. Scrub the lens and strap gently with your fingers, then rinse with clean water.

Techniques to prevent mask fogging

Use a defogging solution: Many divers use a commercial anti-fog solution, which is applied to the inside of the lens before diving. You can do the same to keep your scuba mask clear. Simply apply a small amount of solution to the lens, spread it evenly, and rinse it off with fresh water before diving.

Properly rinse the mask: Before diving, rinse the mask thoroughly with fresh water. This helps to remove any residue that can cause the mask to fog.

Don’t touch the lens: Avoid touching the inside of the lens with your fingers, as oils and residue from your skin can cause the mask to fog.

Proper fit: Make sure the mask fits properly. A mask that leaks air will cause more fogging, as the warm air from your breath will escape and condense on the lens.

Slow and steady breathing: When putting your mask on, breathe slowly and steadily to prevent the warm air from your breath from condensing on the lens.

Hood: Wear a hood to help keep warm air from escaping and condensing on the lens.

Clear it out: If your mask does fog up, you can clear it by exhaling gently through your nose.

By following these tips, you can help keep your scuba mask from fogging and enjoy a clear, unobstructed view underwater.

Clearing a fogged mask underwater

One of the most frustrating experiences for a scuba diver is having a fogged-up mask during a dive. It can make the entire experience unenjoyable and dangerous. Fortunately, there are two techniques that can help clear a fogged mask – partial and full flood clears.

Partial flood clears involve blowing out a small amount of water from the mask while still keeping it on your face. Full flood clears, on the other hand, involve completely removing the mask and filling it with water before clearing it.

Partial flood clear:

1. Tilt your head slightly forward and look down.

2. With one hand, reach up and push the top of the mask away from your face while pulling the bottom of the mask towards your chin.

3. Use your other hand to press the mask against your face and exhale through your nose, letting out a small amount of air to blow out the water.

4. Inhale through your nose, creating a slight suction that will draw the remaining water out of the mask.

Full flood clear:

1. Tilt your head slightly forward and look down.

2. With both hands, grab the top of the mask and pull it away from your face.

3. While still looking down, let water fill the mask completely.

4. Tilt your head back slightly and press the mask firmly against your face, ensuring a seal.

5. While exhaling through your nose, lift the bottom of the mask slightly to allow the water to flow out.

6. Inhale through your nose, creating a slight suction that will draw the remaining water out of the mask.

Remember to practice these techniques before your dive and always ensure you have a clear view before descending. With the proper fit, anti-fog solutions, and cleaning tips, you can help keep your scuba mask clear and have a successful dive.

Troubleshooting common issues:

Sometimes, even with the use of an anti-fog solution, a mask can still fog up during a dive. If this happens, try to avoid breathing through your nose and instead breathe through your mouth.

This helps to minimize the amount of warm, moist air that reaches the lens. Additionally, you can try spitting on the inside of the lens and rubbing it around with your fingers before rinsing it off with clean water. This technique creates a thin film on the lens that can help to prevent fogging.

Dealing with water leakage:

If your mask is leaking during a dive, it is likely due to an improper fit. Check to make sure that the mask is not too tight or too loose. Adjust the strap and try on the mask again before descending. If this does not work, the problem may be due to a damaged or poorly manufactured mask. In this case, it may be necessary to replace the mask with a new one.

Fixing strap or buckle malfunctions:

If the strap or buckle on your mask malfunctions during a dive, it can be a frustrating experience. To avoid this, check the strap and buckle before each dive to make sure they are secure and functioning properly. If the buckle becomes loose or the strap breaks, try to adjust it during the dive. If this is not possible, signal to your dive buddy or guide that you need to surface and address the issue before continuing the dive. It is always better to be safe than sorry!

Be careful of your eyes

I accidentally got something in my eyes during one of our scuba diving adventures, and it made the entire dive unenjoyable. I don’t know if it was the scuba solution for keeping my mask clear, as baby oil shouldn’t sting that much if it gets in your eyes, or if it was possibly my sunblock. But my eyes burned the entire time and I could barely see. Fortunately, it cleared up immediately once I cleared and washed my eyes and everything was fine, but this was an unpleasant experience.

Happy diving!

Scuba diving is an incredible experience, but it’s important to take care of your equipment, especially your scuba mask. There’s nothing worse than having to cut your dive short because you can’t see through a fogged-up mask or an irritant in your eye. Remember, safety always comes first, so make sure to always dive with a buddy, and if you ever encounter any issues, don’t hesitate to signal for help. Now, go out there and explore the wonders of the underwater world with crystal clear views!
