The Queen looked regal in powder blue as her Platinum Jubilee celebrations began on Thursday with a special Trooping the Colour birthday parade.

The 96-year-old monarch took to the Buckingham Palace balcony to watch the RAF flypast alongside fellow senior royals including the Duke and Duchess of Cambridge, Princess Anne and Prince Charles, looking elegant in a custom-made Angela Kelly outfit. The two-piece, which featured shiny pearl and diamante scalloped beading around the collar and front trim, was set off with a pair of orange-tinted sunglasses – but do you know the reason why the Queen wears them?

Yellow, amber, and orange shades enhance contrast for day to day activities and are recommended for people who have undergone cataract surgery thanks to their excellent UVA/UVB protection and glare control.

Her Majesty had a cataract removal procedure at the private King Edward VII hospital in London in May 2018, and has been careful about wearing sunglasses in bright light ever since.

Cataracts are when the lens, a small transparent disc inside the eye, develops cloudy patches. These usually become bigger over time, causing blurry, misty vision and eventually blindness if left untreated.
A person can be more at risk of developing them if they have a family history of cataracts.
The Queen completed her outfit with her symbolic Brigade of Guards brooch, a regular feature at Trooping the Colour over the years.
The diamond piece features the emblems of the five household regiments (the Coldstream Guards, the Grenadier Guards, the Irish Guards, the Scots Guards, and the Welsh Guards).

The Queen led her family in marking her annual birthday parade – a military spectacle that involved more than 1,200 officers and soldiers and 240 horses from the Household Division putting on a display of pageantry. Hundreds of army musicians also added to the festivities as the colour was trooped by the 1st Battalion, Irish Guards.
