  • Blocks 99% harmful blue light with UV400 protection
  • Ultra-light 21g acetate frame for all-day comfort

Butterfly Frame for Screen Users

These lightweight acetate glasses weigh 21g and feature a butterfly-shaped front measuring 53mm wide by 48mm high. The 145mm temples and 18mm nose bridge suit a range of face shapes. They are designed for people who spend long hours at a computer, phone or TV and want to reduce blue-light exposure.

Simple Addition to a Desk Setup

No power, software or special mounting is required; the glasses sit on the nose and fold flat when not in use. They free the user from screen glare and the eye fatigue that builds during extended sessions. The UV400 lenses block 99% of harmful blue light without altering colour perception for everyday tasks.

Consistent Filtering During Long Sessions

The lens coating maintains its 99% blue-light reduction and UV400 protection continuously, so protection does not fade after a few hours of wear. Acetate construction resists warping from the heat of prolonged use. Wearers who need prescription correction will need separate lenses, as these frames ship with non-prescription filters only.

Questions about this item

How long can I wear the 21 g acetate frames before the nose bridge pressure becomes the limiting factor?

The lightweight 21 g construction and 18 mm nose bridge spread pressure evenly, so most users can wear them through a full workday without the bridge becoming the first comfort limit.

Do the lenses trap heat or cause fogging when I keep them on all day at my desk?

The open butterfly silhouette and thin acetate rims allow steady airflow around the 48 mm lenses, preventing heat build-up and fogging during extended indoor use.

Do I need a prescription insert or clip-on to make these work with my existing glasses?

These are sold as non-prescription blue-light blockers with UV400 protection; if you require vision correction you will need separate prescription lenses or contact lenses underneath.
