Excellent posing by Miliswa in Crown glasses made just over forty years ago. In our correspondence she mentioned that she had glasses but no receipt at hand. However, she tested until how far she could see well without glasses and based on that information, I estimated her prescription to be around -1.50. When we met in Brighton, Miliswa produced her glasses and it turned out that she has just a bit of astigmatism. Anyway, it did not really matter for her posing. This is a very credible portrait indeed.
