Digital technology has been instrumental in changing the world we live in today. Other than complaints that we don't talk to one another face-to-face enough, the change has improved our lives for the better.

However, all the screen time has had an impact on the bodies of many people. For example, staring at monitors, tablets or mobile phones taxes our eyes. According to The Vision Council, 65 percent of Americans experience digital eye strain symptoms.

This month, The Pennsylvania Optometric Association is commemorating Save Your Vision Month -- a time when Pennsylvanians are encouraged to take steps to maintain good optical health.

Two renowned Doctors of Optometry join us on Monday's Smart Talk. Dr. Marianne Boltz, an Assistant Professor of Ophthalmology at Penn State Eye Center and Dr. Gregory Caldwell, who practices with Doctors of Optometry in Duncansville answer your eye health questions.

Also, the American Cancer Society's Bark for Life has become one of Central Pennsylvania's most fun and anticipated fundraisers in just a few short years. This year's event is scheduled for April 30th at Indian Echo Caverns in Hummelstown.

According to a news release, Bark for Life is an opportunity for people to be empowered through their canine companion partnerships and to continue to contribute to cancer cures.

Appearing on Monday's program are Diane Phillips, Director of Government Relations for the American Cancer Society Action Network, East Central Division, Anne Lipko who is a cancer survivor and Myra Taylor, Bark For Life Volunteer Event Lead.
