One Canadian firm has increased the price of eye drops from £2.09 to £29.00.
My optician, many years ago, advised against buying eye drops as they were, in his opinion, a waste of money. He suggested instead adding 1 teaspoon of salt to a pint of boiling water and mixing it. Allow to cool then bathe the eyes with the solution.
For those who aren't IMPERIAL MEASURE LITERATE, a pint is about a good piss........ Roughly 564ml.
It's possibly inadvisable to bathe the eyes with piss, though. Just in case,
(You have to be so careful nowadays!)
