About a month ago there was a series of postings about an eye problem which made it very difficult to keep one's eyes open. Although I thought I had been diligent in filing anything I thought might be relevant to me, I let these go and then promptly began to have the problem. Someone, I remember, was very knowledgeable on the subject. Would you please repeat your posting. My apologies for causing extra work. I thank you in advance Nancy Shlaes
