The human eye filters out over 95% of UV light before it reaches the retina, but only a tiny amount of blue-violet light is filtered out. This is where the science comes into play. Between 380-440nm blue light has been scientifically proven to be harmful to the eye and is a possible cause of photoretinitis. Light of this wavelength can also cause eyestrain and disrupt our circadian rhythm by surpressing melatonin production before bed.

In a word, yes. We live in an age dominated by screens, whether iPhone, laptop, tablet or desktop, we all spend hours each day in front of screen emitting artificial blue light. We offer blue light protection to ease eye strain when using screens, to aid sleep when using screens before bed and for eye protection. For presbyopes (people needing a correction for close work) we also offer reading lenses in a +1.00, +1.50, +2.00 and +2.50.

We always recommend starting with a proper eye examination from your local independent opticians. If no other correction is needed, we offer non-prescription lenses that provide protection from blue light, which may be beneficial if you spend a lot of time using screens at home or at work. If you require a correction only for reading, we also offer reading lenses in a +1.00, +1.50, +2.00 and +2.50.

Absolutely! We now offer prescription lenses at an affordable and competitive price with the added benefit of built in blue light technology. Please select your powers on the Shop page when selecting your chosen frame and colour. Shop Prescription Now. 

The reduction of eye strain should be almost instantaneous for most screen users currently suffering. The sleep related benefits may take longer to be noticeable but should gradually increase with continued wear before bed.

Lumiblues are most effective when using screens or before bed but can be worn at any time. The blue light blocking effects can help ease eye strain during the day too, especially when using digital devices, and they block UV light too.

Absolutely! Lumiblues protect from UV light up to 400nm (UV400) as well as 99% of blue violet light up to 410nm. This gradually increases to allow 98% of light through of the visible spectrum past 480nm. This way we can stop the harmful effects of blue light without blocking the beneficial properties or distorting colours.

Lumiblues are high-quality handmade frames, created using premium acetate with spring hinges. Our lenses are CR39 plastic with UV protection, blue light filtering technology and anti-reflection coatings.
