For most people with soft contacts (hard contacts are now rarely used and offered up), swimming is fine. However, the user should not attempt to open his eyes under the water as the contacts would then easily slip beyond the eye and be forever lost.

When in the water, close your eyes when coming into contact with the water (i.e. going underneath the water, swimming across, splashing, etc.) to prevent the contacts from slipping out.

Yes - but your eyes will probably be a bit more sensitive to the chlorine and any other chemicals in the water. If it's daytime it will be tough to protect your eyes from bright sunlight while swimming.
