A simple way to change the light you face.
Filter the light at eye level
Seren’s FL-41 tint changes the light passing through the lens before it reaches your eyes. It is a wearable way to manage the light in your view, including light from screens and overhead lamps.
Take your lens with you
Keep one pair close for a desk, a shared room or another bright setting. You can change the light you look through even when you cannot change every lamp around you.

Your questions, answered
What are FL-41 lenses for?
FL-41 is a rose-toned tint studied for light sensitivity, including discomfort linked to migraine. Seren puts this tint in an adult unisex frame.
What does photophobia mean?
It means light sensitivity: light can feel uncomfortable or painful. A tinted lens is one way to change the light reaching your eyes.
Are these the same as Dante?
Seren uses the same frame shape as Dante, with an FL-41 tint. Dante is our amber blue light option. The tint is the key difference between the two pairs.
Can I order prescription lenses?
Seren is currently offered as a non-prescription pair. Contact us if you need help checking whether the product fits your eyewear needs.
Will colours look different?
Yes. The rose-toned tint changes colour appearance as it filters the light passing through the lens. Keep this in mind for colour-critical tasks.
