Frequently Asked Questions
What does without strength mean?****
With this variation you will get the premium Japanese CR39 lenses filtering out 99,5% off all blue light without the extra magnification some of our customers prefer. The lenses will support your eyes preventing eye strain when using your computer or other digital devices late at night, with improved sleep hormone (Melatonin) levels for better night sleep. We developed the lenses to be as bright as possible and still have benchmark performance, to let through maximal amount of safe light for a relaxed and clear viewing experience.
In what range of nm do the glasses block? And what percentage of light transmits at that nm?****
The lenses filter out 99,5% of the blue light spectrum (380-500 nm), and over 70% of the all green light (500–565nm). This includes the melatonin disturbance zone around 460 nm in the blue light spectrum. Studies have demonstrated that this type of light easily disturbs your sleep, emitted in large amounts by LED:s in your TV, smartphone, and computer screens.
What are the dimensions of the two sizes? I usually need narrow size glasses and I’m wondering if these will fit.****

BLB10 is suitable if you are looking for a narrower fit, with the size 55-17-145 and a total width of 141 mm/ 5.55 inches.

What strength? I wear prescription glasses for astigmatism and far sightedness. Will these glasses fit over my reading glasses?****
You could potentially wear the variant without strength over your reading glasses. The model BLB12 could be a better option as this model have large wrap around style rimless lenses, That will cover smaller glasses without feeling bulky.
Why does it say to order half your strength for readers?****
The strength of reading glasses is described as Diopter (D) which is the inverse of the Focal Length in meter (Diopter= 1/Focal Length). The Focal Length is defined by the distance from the Lens to the Focal Point, the point where the Lens will Focus.
How many percent blue light is it blocking?****
The custom-made lenses filter out 99.5% off all blue light and a large amount of the green light spectrum.
Do these glasses amplify light? My eyes hurt when wearing these in a lighted room or when I stare directly at the computer with them on.****

Can you return if it doesnt fit?****
Yes
Why do the regular size cost $10 more than the wide fit?****
The price without the reading lens addon is the same for the regular and wide variation. The variations with reading lenses cost more to manufacture, thereof the price difference.
