I have worn glasses/contact lenses for short sightedness for about 30 years. There was always a small pay-back in that I could see well close up as a side effect of being short-sighted. Now however my eyes have caught onto this and have managed to become short and long sighted at the same time. So when I wear contact lenses my arms are becoming too short and so I need reading glasses. Off the shelf ones fortunately rather than more prescription ones. So off I went to Boots, £20-£30, then Tesco £3-£9. So I don't have a clue what to do. Any suggestions / recommendations from people who use off-the-peg reading glasses?
