Research has investigated red and near-infrared light for a range of biological and visual applications. Areas of research include cellular energy metabolism, retinal function and age-related changes in visual performance.

Lukirch V3.0 is intended for personal wellness use and is not intended to diagnose, treat, cure or prevent any disease.

Individual experiences may vary. Research findings should not be interpreted as a guarantee of a particular result from this product.

1. Fully charge the glasses before the first use.
2. Put the glasses on comfortably. They can be worn over many regular prescription glasses.
3. Select the desired timer setting: 10, 15, 20 or 30 minutes.
4. Use according to the product instructions and your personal comfort level.
5. Turn off the device after your session if the automatic timer has not already stopped it.

For detailed operating instructions, please refer to the user manual supplied with your glasses.

670nm red light has been investigated in photobiomodulation research, including studies involving mitochondrial function, retinal cells and visual performance.

Can red light therapy improve vision?

Research has investigated whether specific wavelengths of red light may influence visual function and age-related changes in the visual system. Results vary by study, protocol and participant characteristics.

How often should I use the glasses?

Follow the recommended usage instructions supplied with the product. V3.0 provides 10, 15, 20 and 30-minute timer settings so users can select the session length appropriate for their routine.

Why does V3.0 weigh only 55g?

V3.0 uses a redesigned lightweight construction and a simplified one-row LED layout. The result is a lighter overall product compared with V2.0, which weighs approximately 65g.

Can I wear V3.0 over prescription glasses?

Yes. V3.0 is designed to fit over many standard prescription glasses. Individual fit may vary depending on the size and shape of your glasses.

Is V3.0 suitable for dry eyes?

Red light and photobiomodulation have been investigated in research related to ocular surface and eye wellness. However, V3.0 is not a treatment for dry eye disease, and individual experiences may vary.

Can V3.0 treat glaucoma or macular degeneration?

V3.0 is not intended to diagnose, treat, cure or prevent glaucoma, macular degeneration or other eye diseases. If you have an eye condition, consult a qualified eye-care professional before using light-based products.

Can I use the glasses after eye surgery?

If you have recently undergone cataract surgery or another eye procedure, consult your ophthalmologist before using red light therapy glasses.

Why don't I notice an immediate effect?

Research protocols vary considerably, and individual responses to photobiomodulation can differ. A lack of an immediate noticeable sensation does not necessarily indicate whether a light-based routine is or is not having an effect.
