TL;DR
Hydrogen-rich saline (HRS) treatment helps repair eye damage caused by blue light by speeding up the recovery of important light-sensitive cells in the retina.
Key Finding
Hydrogen-rich saline accelerated recovery of light-sensing retinal cells and melanopsin protein expression in rats with blue light-induced eye damage, with measurable improvements in retinal function within two weeks.
Summary
Researchers exposed rats to intense blue light to damage their retinas, then treated some with hydrogen-rich saline (a salt solution containing dissolved hydrogen). They found that blue light damaged special light-sensing nerve cells in the eye, but hydrogen-rich saline sped up the recovery of these cells over two weeks. The treatment increased levels of a protein called melanopsin and improved electrical signals in the damaged retina.
Practical Takeaway
This is an early-stage animal study showing hydrogen-rich saline may help protect against blue light damage to the eye. However, results in rats do not automatically translate to humans, and much more research would be needed before any therapeutic use. The study does not tell us whether hydrogen water (which people can actually consume) would have similar effects.
Abstract (excerpt)
Excessive exposure to blue light can cause retinal damage. Hydrogen-rich saline (HRS), one of the hydrogen therapies, has been demonstrated to be effective in eye photodamage, but the effect on the expression of melanopsin in intrinsically photosensitive retinal ganglion cells (ipRGCs) is unknown…
