Favorite Color:  White

Favorite eye care product:  One-day disposable contact lenses.  I started wearing contact lenses at 11 years old, when contact lenses were worn for an entire year (or more).  Contact lenses were super expensive for just one pair, plus cleaning was tedious.  Today, I wear a fresh pair everyday, and enjoy crisp vision without the maintenance.
