Kate Evans, 25, said the device she created to help her battle insomnia as a student is now available online.
She designed the Light Sleeper while suffering from insomnia during her time as a product design student at the University of Central Lancashire and involves a blue light that moves across the bedroom ceiling, UPI.com reports.
It moves your eyes along a line, relaxing your brain," Evans said. "This helps you drift off. Reading a book can make you more alert but this makes you switch off. It's the first device that offers a simple, drug free and natural way of falling asleep for those who find it hard."
Evans, who now works as a design director for firm Quincom in Oxford, said the company has been receiving large numbers of orders for the product from Japan.
