All four of our opticians have an iPad at their workstation. We use them to take client photos and to do personal research on frames and lenses. We also love to use them daily to teach patients about lenses. This is a picture taken from our HVC Viewer from HOYA. We use it to educate on progressive, polarized, and photochromic lenses, BlueControl treatment, and, as pictured, anti-reflection (non-glare) treatment. It gives our patients a great visual about what premium non-glare does for them! Find and use a quality optical App (like the HVC Viewer) to help you educate patients with pictures and videos.
