Sad reason Simon Cowell always wears orange glasses

Simon Cowell has been back in the limelight recently thanks to his new series, Simon Cowell: The Next Act - and it's got fans puzzled over one of his fashion choices.

The six-part new Netflix show, which landed on the streaming service on Wednesday (10 December) sees the 66-year-old music mogul try and find the next big boyband.

Now, we know that the Britain's Got Talent judge is no stranger to cherry-picking talent, and he's put together some of the biggest groups the industry has seen, such as One Direction, Little Mix and Westlife.

And now, he's put together another boyband, called December 10 - a seven-piece group who have signed to EMI/Universal after they were chosen on the show.

But as we say, while watching the documentary, eagle-eyed fans have picked up on one fashion detail when it comes to Simon, which is that he's always wearing orange glasses.

The father-of-one is rarely seen without the bright accessories on his face, and it turns out there's actually more behind it than just personal style.

He was forced to speak out on his health last year after reports began swirling that he was battling a 'mystery illness' after missing BGT filming.

Simon said on Instagram at the time, as per OK! Magazine: "I just found out according to the internet, I have a 'mystery illness'.

"For anyone concerned, I missed two auditions at the end of one day, two weeks ago, because I do get migraines after long days in the filming lights."

He added: "PS. This is why I wear these glasses!" alongside a photo of him in his judge chair wearing the specs.

As per the Association of Migraine Disorders, one of the most common migraine symptoms is light sensitivity. For some individuals, flashing, bright, flickering, fluorescent or colourful lights can also act as a migraine trigger.

So, migraine glasses are designed to filter out or block certain wavelengths of light to help ease photophobia.

There are a slew of different options for migraine glasses with different types of lenses and degrees of tint, including rose/pink tints or more neutral green-grey/light gray.

Whilst it isn't confirmed which exact kind of glasses Simon wears, Kevin Weber, MD, assistant professor of neurology at the Ohio State University Wexner Medical Center, spoke to SELF about the potential prescription.

He explained: "This is a type of tint designed to block the blue light portion of the light spectrum."

Fans have since taken to social media to comment on the phenomenon, with one Twitter user writing: "Some glasses have coloured lenses because they help with light sensitivity. If you watch BGT, you'll see Simon Cowell wears orange lenses glasses for the very same reason."

While a second wrote: "Saw Simon Cowell in an interview say he wears the red lens glasses as they help minimise his chronic migraines."

And others have previously questioned: "Why does Simon Cowell wear them pink glasses??? #BGT".

Well, now we know!
