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.

I was born and raised in Chicago.  I recently moved from Chicago to Southern California.  I love knowing that I’ve helped someone achieve clear sight with getting glasses or contacts. Being able to see them smile and say “everything is so clear!”
