The 20-second advert for Thealoz Duo drops, which will be shown on ITV3 from October 19 for six weeks, says the drops can relieve dry eye symptoms without preservatives. 

The product – which contains trehalose 3% and sodium hyaluronate 0.15% – can be used as often as necessary during the day and is suitable for contact lens wearers, Thea Pharmaceuticals said.

One 10ml bottle of Thealoz Duo retails at £13.99.
