Does it hurt to look underwater?

The occasional glance should be OK, but extended eye opening underwater can cause damage. "The eye becomes red, irritated. You might become photophobic, or sensitive to light. Your vision might blur a little bit, and your eyes are going to feel irritated or even, frankly, painful," says Dr.

For many people, the hot summer days are often spent swimming at the pool. But even though the water is usually clear with chlorine, it doesn't mean you should be looking underwater. Journalists: Broadcast-quality video (0:59) is in the downloads at the end of this post. Please courtesy: "Mayo Clinic News Network." Read the script. The next time you dive in, you might want to reconsider opening your eyes underwater. "Chlorine is a pretty powerful disinfectant and can, in fact, cause some damage to the outer layer cells that protect the cornea," says Dr. Muriel Schornack, a Mayo Clinic optometrist. The occasional glance should be OK, but extended eye opening underwater can cause damage. "The eye becomes red, irritated. You might become photophobic, or sensitive to light. Your vision might blur a little bit, and your eyes are going to feel irritated or even, frankly, painful," says Dr. Schornack. Most of the time, those symptoms are uncomfortable but temporary. If you really want to look underwater, the doctor-recommended tip: "… I'm a huge fan of swimming goggles for a couple of reasons. No. 1, you can protect the front surface of the eye. No. 2, a lot of folks who are highly nearsighted or highly farsighted like to wear their contact lenses while they're swimming. And if chlorine soaks into those lenses, now you've got a reservoir of chlorine on the surface of the eye that's likely to do damage," says Dr. Schornack.

What is a stealth flag?

The Stealth (ST) flag allows the player to be invisible to other players on the radar. The only way to locate a player with a Stealth flag is to either see them on a screen, see their shots, hear them jump around, or nullify their flag's effect through the use of the Seer (SE) flag.

Tactics

With the ability of locating and tracking the movement of tanks on radar being really powerful and commonly utilized, the Stealth flag allows the holder to hide and plan a surprise attack. While being able to prevent the opponent from locating the holder is a lot in itself, the actual usefulness of the flag comes from the tactics used while in pursuit. To increase the odds of successful assassination, the holder should hide from the opponent while moving closer, only attempting to shoot when in close proximity. This is to prevent giving away one's location and restrict the opponent from performing any reactions that could save them. A holder of the Stealth flag should jump as least as possible to stay quiet, as well as always look at where the opponent is facing and where they are moving, so they can position themselves accordingly. Planning the route of the opponent is one of the essential factors, as driving to a foreseen point of intersection and awaiting the opponent behind an object before swiftly killing them is one of the most common and effective methods of Stealth assassinations.
