What is the difference between "intensive eye drops" and "contact lens eye drops"? Scientifically nothing, but if the box has a picture of contact lenses on it, you may pay more.

The PM programme has found that identical or very comparable eye drops are being sold for higher prices depending on whether they are aimed at the contact lens market or not.

One supermarket, having been informed by this programme of its higher price for the contact lenses box, has now reduced it.

Reporter Jon Manel brought two different types of eye drops in to the studio to show presenter Carolyn Quinn.
