Frequently Asked Questions · Patient & Client Guide
Tap any question below to view details regarding lenses, testing, and appointments.Where can I test and buy authentic Sleepaxa glasses in Srinagar?
Authentic Sleepaxa migraine and gaming eyewear is officially dispensed at Keen Sight, Auqaf Building, Soura, Srinagar. We handle trial fits, facial measurements, and direct orders cut in the Sleepaxa lab.
Can I get my custom prescription in Sleepaxa FL-41 or gaming lenses?
Yes. Keen Sight dispenses zero-power, single-vision distance/reading, and wide-corridor progressive lenses across 1.56, 1.67, and 1.74 ultra-thin high-index materials.
How does FL-41 compare to ordinary blue-cut lenses?
Generic blue-cut lenses only reflect high-energy purple light (around 400–420nm) and do nothing for migraines. Sleepaxa FL-41 uses specialized rose-tint dye chemistry to filter the 480–520nm band, which directly soothes the optic pathways that trigger migraine attacks.
Why does Sleepaxa DayActive 1.0 use a yellow tint for gaming and desk work?
Clear screen coatings let most high-energy visible (HEV) light through. DayActive’s MR8 mid-yellow substrate filters the harsh 380–450nm band while boosting contrast, which eases eye fatigue during long screen hours.
What is NeuroCalm FLX+™ and how does it differ from standard FL-41?
NeuroCalm FLX+™ (Patent IN 587746) is a dual-band smoke grey-green lens with 22% VLT. It provides deeper filtration for severe light sensitivity and post-concussion photophobia, and is dispensed through clinical consultation at Keen Sight.
Can I wear these glasses while driving?
FL-41 Light (60% VLT) and DayActive 1.0 (76% VLT) can be worn for daytime driving. Deep tint lenses like Circadian560™ (17% VLT) and Red Sleep (15% VLT) must not be worn while driving.
Are Sleepaxa photobiological glasses classified as medical devices?
Sleepaxa products are assistive visual-comfort eyewear engineered using photobiological wavelength filtration. They are not medical devices and do not substitute for formal clinical diagnosis or treatment.
How long does it take to receive custom prescription orders?
Zero-power orders dispatch within 4–6 working days. Custom prescriptions cut and finished in the Sleepaxa optical lab dispatch in 7–9 working days, backed by a 1-year frame warranty and a 6-month coating guarantee.
