Her appearance in a visor comes a month after she first donned the plastic face covering, making her the first royal to do so.

However some social media users noted Camilla appeared to wear the visor ‘too high’ on her head to provide adequate covering of her face.

UK-based pharmacist Navid Sole also warned a visor is not as effective as a face mask in stopping the spread of Covid-19, although it is better than wearing no face covering.

The royal also kept the blue floral mask on under the visor to ensure maximum protection.

The Earl of Wessex, 56, who lives with his wife Sophie, 55, and their children Lady Louise Windsor, 16, and James Viscount Severn, 12, at Bagshot Park, between Windsor and Guildford, visited Yvonne Arnaud Theatre yesterday. 

His engagement came as a study warned that plastic face shields allow nearly 100 per cent of tiny airborne droplets released by coronavirus-infected patients to escape through visors.

It’s been a busy week for the Duchess, who yesterday met well-wishers to visit a cancer charity Maggie’s Barts, donning a green itak print facemask.

The Duchess, who has been president of Maggie’s since 2008, looked in high spirits as she made her way into the medical facility, wearing a stylish emerald green pleated dress – to the knee – and accessorising with a matching black leather Chanel handbag.

Revealed: Why plastic face shields DON’T work unless used in combination with other safety measures

In a scramble to find ways to protect people from catching the coronavirus, masks, goggles, visors and gloves have all been touted as possible layers of protection.

Some people have even been seen with homemade attempts, such as wearing lunchboxes or water bottles over their faces.

But do visors work?

Some research has shown that people are at risk of becoming more seriously ill with COVID-19 if they receive a larger ‘viral load’ – the first dose of viruses that they are infected with.

Epidemiologist Dr Eli Perencevich and a team of scientists at the University of Iowa said a visor could reduce the amount of virus someone inhaled by up to 92 per cent form 2m away from the source.

They said: ‘Face shields… should be included as part of strategies to safely and significantly reduce transmission in the community setting.’

Dr Robert Glatter, a doctor at Lenox Hill Hospital in New York City, said that early data was ‘promising’.

But research carried out before the pandemic does not show any clear benefits of using visors on their own, other scientists say.

A study by the US Centers for Disease Control & Prevention (CDC) done in 2016 found there is no proof to back up claims that face shields work on their own.

He said viruses or bacteria could come in through around the edges of the visor and still cause infection — and said they should only be used in addition to other PPE.

Lawrence Young, a virologist and oncologist, University of Warwick, told MailOnline: ‘I don’t know of any systematic studies properly evaluating the benefits of face shields.’

He noted an ‘interesting’ review led by the University of Hong which comprehensively explored the different types of facial protection measures, including masks.

The team highlighted the fact that ‘strong evidence is lacking in terms of the effectiveness of face shields against the transmission of viral respiratory diseases’.

Writing in the journal Oral Diseases, the team add: ‘Because most face shields do not form a tight seal around the side of the face and chin area, they do not offer protection against aerosols leaking in from the margins of the face shields.’
