I wanted to warn others about Tesco Opticians. I have had two bad experiences from their branch in Yeovil. I bought prescription sunglasses which I was pleased with until the the arm came off one side and was not repairable, apparently. This was within less than a year of purchase and the staff were very unhelpful and refused to replace them. I rather stupidly purchased a new pair as the deal seemed good with an extra pair free. One pair in black with dark grey tint and the same sunglasses in brown with a brown tint as advised. The brown tint turned out to be bright orange and totally useless. Tesco staff insisted this was the correct colour and not a mistake and again I felt cheated and mistreated because of their incompetence and lack of concern for their customer.
