Hi there: You have to have had a cataract op to fully realise the difference it makes ... the 20-minute procedure is worth every penny! I say this wisely, as I have had the one eye done in South Africa (where I live these days). It's costly, here, but imagine it to be a lot cheaper(?) in the UK. I'm 68 years of age, still ride a motorcycle and now I can really see the antics of idiots in 'tin boxes' now (LoL) Just one reason to be able to see clearly ...
