This study was published in 2008, looking at people with age related macular degeneration.
This is the most common cause of vision loss with age and can cause blurry vision and just having worse overall eyesight.
The macula is a central region in the retina, the part of the eye that helps facilitate vision.

They used a laser of red light applied to the back of the eye.
◈ Wavelength: 780 nm (near-infrared)
◈ Laser type: Semiconductor diode, continuous emission
◈ Power output: 7.5 mW
◈ Frequency modulation: 292 Hz
◈ Spot diameter: 3 mm (collimated beam)
◈ Irradiation time: 40 seconds per eye
◈ Energy density (fluence): 0.3 J/cm² per session
◈ Total dose: 1.2 J/cm² (4 sessions, 2 × per week × 2 weeks)
◈ Application site: Transconjunctival (through the sclera, not through eyelid)
◈ Distance from eye: ~1 cm from ocular surface
◈ Beam target: Toward macular region with eye turned inward (adduction)
◈ Power reaching retina (estimated): ≈ 1–2 mW after tissue attenuation
◈ Thermal profile: Sub-thermal (non-heating, purely photobiomodulatory)
You DO NOT want to stare into a red light. If one was to use this with a normal non laser device, closing the eyes and allowing the red light to penetrate through would be a better option.

After just 2 weeks (2 treatments per week) - red light improved nearly EVERYONE'S vision.
Not one person's declined, and out of 146 eyeballs, only 4 stagnated.
The rest improved. measured by standard visual acuity testing.

The same was true for people with cataracts.
Out of 182 eyes, only 10 showed no improvement.

Red light also improves color perception / blindness.
Each line in the diagram connects colored caps that the patient placed in order of perceived hue.
Crossed, disordered lines mean the patient’s color perception was distorted before treatment.
After, they were able to accurately perform the test, meaning their color perception was fixed.

How exactly does this work?
Macular degeneration typically involves a few key steps:
➜ Oxidative degradation of lipids in the retinal pigment epithelial cells (lipofuscin)
➜ Accumulation of old photoreceptors (proteins that help convert light into vision)
➜ Slowed phagocytosis (clearing of old photoreceptors)
➜ Eventual cell death
Red light stimulates the metabolism within these cells, which helps by:
➜ Increasing phagocytic clearance and renewal of photoreceptors
➜ Improving cell survival / antioxidant status

This is a suitable device to use. If this is to be used the eyes should be shut, about 6-12 inches away and only for very brief periods (maybe 1 min 2-3x a week).
