Enough to keep you from dying. After undergoing and extended research, no exact number was revealed for the pressure a dive mask must withstand. Although they obviously must withstand thousands of pounds of pressure due to the weight of the ocean water that one will be wading through.

Can you scuba dive wearing an oval mask?
Yes. It would be more comfortable if it covers the nose as well. You can dive without a mask, but you would find it difficult to see and you wouldn't be able to read your instruments. Plus it wouldn't be very comfortable especially if diving in salt water

How much force from a puck can a hockey mask take prior to cracking?
The average hockey puck can travel at speeds of up to 140 kilometers per hour and so a mask must be able to withstand at least that, and repeatedly. The amount of force a mask can receive before it cracks will depend on how many layers it has and it's overall construction, but one a crack is suspected it should not be worn.

How do you stop your scuba goggles from hurtting your forehead?
First, in American parlance, "goggles" refer to lenses that fit the eyes but don''t cover the nose. If this is the device you're talking about, you cannot use it for SCUBA. The nose has to be covered so that you can equalize air pressure in the mask with outside water pressure. Next, you shouldn't ever wear your mask on your forehead. If you're wearing it, it needs to be over your eyes or around your neck. Wearing a mask on your forehead is a great way to lose a mask -- annoying on the boat and dangerous in-water. FInally, if you mean your forehead hurts when you're wearing your mask on your eyes, it sounds like you have the strap too tight. Do this at HOME: 1. Loosen the strap so it doesn't hold the mask on at all. 2. Press the mask onto your face and inhale. If the mask sticks to your face for 10 or more seconds, great --- it fits. If it readily falls off, this mask doesn't fit you. Go get a mask that does fit (using steps 1 and 2 at the dive store), and start this procedure again. 3. If you're here, your mask fits. Now, tighten the strap a little, so that the least pressure possible to hold the mask on your face is what you're getting from tyhe strap. Then tighten it just a little more.

How do you see under water after you dive?
You have to use a diving mask. The air between the mask lens and your eyes helps you to see clearly. Diving without a mask results in everything looking blurry because you're just looking directly through the water.
