Contacts fall out a lot. They fell out more often when the only ones were hard lenses. Soft lenses conform to the shape of the eye, are larger in diameter and are tucked under the eyelids, so they usually don't move out of place or fall out. Plus, they're usually more stable than glasses, especially for sports. Contact lenses are expensive.
Contact lenses are hard to care for.
Not at all. Today's lens care systems are easy and quick to use. Many contacts can be ready to wear in just five minutes. Contact lenses are not safe to wear for sports. Except for water sports, contacts are very safe.
