LEE COUNTY, FL - The glasses are called, "Superfocus". If you've got a collection of "specks" for reading or watching TV, keep reading. The glasses use a unique technology to focus both close up and far away without the need for bi-focals or tri-focals. Simply slide a tiny button on the bridge of the glasses and they focus to your needs. With a doctor's prescription the glasses are custom made for the user. The glasses have even been approved by NASA for shuttle crew use. You can find Superfocus glasses in higher end eyeglass boutiques.
