Spectral control
Reduce selected artificial light
A unique dye in the lenses reduces light from sources including LEDs and high-pressure sodium lamps, helping the night sky appear less orange and more natural.

Kenko Star Cluster Glasses
Bring the night sky back into view. Keep its natural colour.
Spectral control reduces selected artificial light, while 83% visible light transmittance and ES lenses support clear, wide-field stargazing.
83%
visible light transmittance
33 g
approximate net weight
140 mm
temple length
Less urban glow. More attention on the sky.
Multi-coated lenses
Preserve useful transmission
Kenko combines its spectral design with multi-coated lenses and approximately 83% visible light transmittance.
Over-glass frame
Keep your prescription glasses on
The frame is designed to sit over prescription eyewear. Fit depends on the shape of your existing frames, so not every pair will be suitable.
Lightweight design
Only about 33 g
The TR-90 frame keeps the glasses light at approximately 33 g for meteor showers and broad sky sweeps.
Targeted spectral response
Reduce the colours that feed urban skyglow.
Kenko's official transmission graph shows an approximate 10% reduction around blue light and an approximate 25% reduction around yellow and orange light. The aim is a less orange-tinted sky with stars easier to distinguish.
Itoh Optical Industrial ES lenses
Spend less effort chasing focus. Keep scanning.
The Extended Depth of Field Design keeps a broader range of distances in focus. That reduces the need for constant, precise refocusing during wide-field stargazing and meteor-shower observation.
Made for broad sky views. With honest fit guidance.
Meteor showers and wide-field stargazing
The ES lens design supports observing across a broad field without continual fine refocusing.
Prescription-glasses wearers
The over-glass frame can sit over prescription eyewear, but compatibility depends on the shape and size of your existing frames.
