You will notice when looking at your Pinhole glasses, that there are four triangles, one in each corner of each lens. Pinholes are best worn when watching TV or reading. When reading always make sure adequate lighting is supplied. As you look through Pinholes some light is cut out. Your eyes may take a little while to adjust to Pinholes, but in a short period your eyes will not notice that they focus through these tiny holes. That is why watching TV is ideal, you forget very quickly that
you are wearing them.Pinholes should be worn for a few hours a day, or as often
as possible.
Never wear your Pinholes when driving or doing any activity where sideways vision is required. Do not use as sun glasses. Always make sure your Pinholes are clean and check no holes are blocked, it is very important to have complete vision.
