Taking part in Strictly Come Dancing alongside my role in Casualty has made this winter even busier than normal for me.

I’ve had a blast, but I’m looking forward to spending quality time with my family.

Seeing the joy on our loved ones’ faces makes Christmas truly special and I can’t imagine celebrating without seeing my son’s smile.

However, many people are denied these memorable sights because they have become needlessly blind.

I am an ambassador of Sightsavers, the charity that works to prevent and cure blindness in developing countries.

Sightsavers has pledged to make A Million Miracles happen in some of the world’s poorest countries and your readers have the chance to make a real difference to someone’s life this Christmas.

A cataract operation takes around 10 minutes and only costs Sightsavers £30.

With the UK government doubling all donations made until the end of the year, for just £15 readers can give a blind person back their sight.

In other words, for the price of a string of fairy lights or a box of Christmas crackers, someone who’s been living in darkness could get an amazing present and see their family’s faces once again.

I have been supporting Sightsavers for many years and have witnessed the incredible impact of their work first hand in India. It is life-changing.

So with this in mind, I would urge readers to please help Sightsavers perform a Christmas miracle by donating £15, or whatever they can, and give the gift of sight at www.millionmiracles.org
