Here’s a common question, about the use of corrective lenses while indoors.

You have your normalized for distance vision, often emphasized for outdoor use.  And you have your differential glasses, for sustained single point focus close-up use.  This invites the question what you might do with all the in between distances?

Note that I keep track of commonly asked questions that come in on Facebook, e-mail, and the forum.  There’s a who list of them that sooner or later may make it to our Youtube channel.  So while I usually only ask individual inquiries in the BackTo20/20 support forum, it’s quite likely that sooner or later most questions will be covered here.

I try to post new content at least once or twice a month.  Subscribe to the channel, if you haven’t yet!
