Frequently Asked Questions

UV420+ lenses filter high-energy visible blue light in the 400-420 nm range, reducing glare, eye fatigue and the visual discomfort caused by prolonged screen use, while keeping color perception natural.
Who should wear blue cut lenses?
Anyone who spends several hours a day on digital devices — office workers, students, gamers and even children using tablets for study. Blue cut lenses are a simple upgrade for everyday wear.
Are Giofine blue cut lenses available as semi-finished blanks?
Yes. Blue cut is available both as finished lenses and as semi-finished blanks for RX labs, covering 1.499 to 1.74 indexes so labs can surface any prescription.
