My philosophy is, why buy a plain old version of something when there is a super geeky version out there with a huge features list? These High Definition Swim Goggles are a perfect example.

The goggles prevent fog while filtering 100% of blue light to improve contrast, shadow definition, and depth perception underwater. The UV-protective curved lenses dont distort vision along the frame edge and and one panelist noted that the goggles seemed to repel water. Easily adjusted, the goggles have an easy-lock side clip that fastens securely and releases with the push of a button. One-piece flexible frame with soft silicone gasket. Panelists observed the suction was ideal for maintaining a tight seal without discomfort.

In my experience, any product that provides “ideal suction for maintaining a tight seal” is worth picking up.

Price: $24.95
Update: It appears that these are no longer for sale and the store recommends these goggles as the best swim goggles.
