Do these glasses actually block blue light?

The lenses carry a blue light-filtering coating aimed at screen light. Kanastal does not publish a blocking percentage, so the effect is milder than glasses with measured filter ratings.

Can I wear them over contact lenses?

Yes. They are non-prescription glasses, so they can be worn on their own or over contacts. They are not designed to fit over another pair of glasses.

Are they good for gaming?

They are light enough for long sessions and cut some screen blue light. They do not add magnification or anti-glare tinting beyond the coating.

The listing describes the glasses themselves. A case or cleaning cloth is not stated, so plan to store them in one of your own.

Will they fit a large head?

The frame is a standard rectangular shape in polycarbonate. No temple length or frame width is given, and there are no adjustable nose pads, so fit is fixed.

Do they help with sleep?

Kanastal claims reduced blue light exposure may support better sleep after evening screen use. That is a general claim about blue light, not a measured result for this pair.

Our take on the KANASTAL Blue Light Glasses

The Kanastal Blue Light Glasses are rectangular glasses with a black frame and a blue light-filtering coating on the lenses. Both frame and lenses are made of polycarbonate, which keeps them light and impact-resistant for long screen sessions. They are aimed at gamers, students and office workers who want a simple pair for monitor use. They are a basic, budget-minded option: there is no prescription, no adjustable nose pads or spring hinges mentioned, and no blue light blocking percentage is stated, so they sit below brands that publish measured filter ratings.
