I suffer with double-vision which is being treated by the local hospital eye clinic. It has got worse with time, and it started as tiny spots before my eyes. The optician told me it was “floaters”, bits of debris , but I decided to see the eye doctor for a second opinion. After doing some tests she told me I had a small retinal detachment which was causing the double-vision, and making it difficult to read, watch tv, and spoiling day to day living.
The doctor prescribed “prisms” to be fitted to my glasses, to reduce the effect. The prisms are made from a flat lens, called a Fresnel lens and take just minutes to fit.
They seem to do the trick and reduce the double-vision. I continue to get the spots before my eyes though I don’t notice them so much now. My Parkinson’s advisor told they were caused by the condition and that they might go away.
