I have the same problem. After trying many things (solutions, mechanical and chemical cleanings, no eye make up, etc.) the optician finally ordered a new pair of lenses, but cloudiness still happens. It seems to occur in the morning if I put my lenses in within an hour or two of getting up. I take them out several times to clean them and eventually they are fine (usually). If I wait until later in the day to put them in, there is no cloudiness. This is very frustrating! I have worn RGP's since 1986 and never had a problem until about 2 months ago.
