The EyePal Care Manual is short and sweet. Clean glasses are a must with static-cling EyePals. The other challenge is finger oil so wash the EyePal with hand soap and warm water, dry it and with it on your fingertip, rub it on a piece of fleece or polyester to charge it up. It should stick to your fingertip when charged up this way. Store EyePals in their included Contact lens Case to keep them clean.
