Focusing flippers help to train our eyes in accommodation, which is changing our focusing from distance to near. Specifically, flippers help improve accommodative facility - the ability to increase and decrease focus on demand. A variety of binocular vision problems cause a decrease in our ability to accurately focus: some people focus too much and cannot relax, other focus too little and experience blurry vision for close tasks. The flippers you are given have lenses on one side that require you to relax your focus (magnifying lenses), and the other side requires you to focus more (minifying lenses).
If the bold side becomes easy to read, try the low-contrast chart on the reverse side. If you learn all the words on your Innovative Eye Care chart ask your optometrist if you can use normal reading material on a book/magazine or computer in the same way - flipping the lenses over at the end of each line. Make sure the print is small enough to challenge you to focus on it clearly.
Remember: For these exercises to be effective, the words you are looking at need to be clear and single. Ask us if you have any questions about the exercises.
