Frequently Asked Questions
Quick answers on standard customer questions on one page.
Premium vs Standard
Premium lenses are custom-made from premium materials with very good optical properties, which means that production takes longer up to one month. At the same time, with the premium line, it is possible to define diopters, which is not possible with the Standard lens.
Premium 550 (Sunset - Red/Orange)
The color of the lens is between orange and red with excellent vision. The premium lens is made of excellent optical material with perfect optical properties and surface treatments, which, however, act on the filtration so that the lens gently transmits wavelengths below 550nm.
Premium 530 (Sunset - Orange)
Premium 530 are recommended for people who have a problem with a given limited number of colors due to anxiety or depression, but need to improve sleeping and regeneration. These lenses transmit the entire spectrum of colors, but reduce it below 5% of the color transition of the spectrum up to 530 nm.
Premium 450 (Daytime - Yellow)
Premium daily lenses are a softer yellow than Standard one. The lenses have excellent properties in reducing the light spectrum below 20 percent up to 450nm. They are suitable for daily use while working, driving, playing games, watching TV, etc.
Standard 550 (Sunset - Red)
Deep red lens made of high-quality optical material blocking up to 550 nm. Without the possibility of using a diopter
Standard 450 (Daytime - Yellow)
A richer yellow lens than the premium one, made of high-quality optical material without the possibility of dioptric adjustments.
