How to test your swim goggles' quality?

Here are three tests to quickly asses the quality of swim goggles:

1. Are the lenses comfortable? Leave the straps off, and push the lenses against your eye sockets. This will give you a quick idea on if the lenses will be comfortable enough for you to be worn for an hour or two at the pool. The lenses will be more comfortable if they are padded with gaskets made of foam rubber or silicone. Also check that the nose bridge doesn’t cut your nose and hurt.
2. Now push the lenses some more against the eye sockets, then release them. The goggles should stick on your face a few seconds thanks to the suction, even if the straps are off. If this isn’t the case and the swim goggles fall off, they will leak water and be useless.
3. If the goggles pass the first two tests, put the straps on and see if the goggles are still comfortable. Check if the lenses don’t suck too much on the eyes or that the straps must not be tightened too fast.
