Did You Know Baking Soda Improves Our Eye Sight?

Scientists have found that baking soda can alter our vision by changing the visual signal generated by photo-receptors in the eyes.

Researchers have revealed how baking soda can improve our vision, as it is well known that it serves many other purposes.

The research from the Makino Laboratory at Massachusetts Eye and Ear/Harvard Medical School and colleagues at Salus University, describes how bicarbonate or baking soda alters the way we see by modifying the visual signal generated by rod and cone photoreceptors that detect light.

Experts Recommend Children to Undergo Early Vision Health Screening
A report published in the January issue of Optometry and Vision Science, official journal of the American Academy of Optometry, recommends children to undergo vision health screening.

Within rods and cones, a small soluble molecule, cGMP, links photon absorption to the electrical activity of the photoreceptor. In the light, cGMP is destroyed and ion channels are closed. Positively charged sodium ions cease to enter the rod or cone and the membrane potential becomes more negative or hyperpolarized. Bicarbonate directly stimulates an enzyme called guanylate cyclase that synthesizes cGMP.

Lead author Clint Makino, Ph.D. said that by opposing the effect of light, bicarbonate limits the size of the photon response and quickens its recovery. As a result, sensitivity to light is slightly lower but our ability to track moving objects is improved.

"An intriguing implication is that vision may change with metabolic state, although further research is necessary for confirmation. It is now known that in some types of retinal diseases, a genetic defect causes cGMP in the rods and/or cones to rise to abnormally high, lethal levels. Once lost, rods and cones are not replaced, so an irreversible blindness is the tragic outcome."
