The secret to improving your eyesight? Just add oxygen (and millions of years of evolution).

A recent study by an international team of researchers has shown just how crucial a consistent oxygen supply was for the evolution of a thicker retina, leading to enhanced vision. The retina, consuming more oxygen than any other organ in the body, is at increased risk of damage if it doesn't receive sufficient oxygen-rich blood. 

Insufficient oxygen can cause the cornea to warp, become less transparent, reduce pain detection, and lead to scarring. New blood vessels from the sclera (the white part of the eye) may grow into the cornea, causing additional damage and scarring. A bloodshot eye is a response to the cornea seeking alternative ways to obtain more oxygen. Since the cornea lacks blood vessels, the retina increases vein activity to absorb more oxygen. This reaction may lead to complications like corneal neovascularization and macular degeneration over time.

The oxygen supply to the cornea is somewhat reduced when covered by contact lenses. Modern contact lenses are designed to be more permeable, allowing greater oxygen flow to the eye, and some are intended for extended wear. Consult your optician to ensure you're using the right type to prevent eye damage. Early symptoms of oxygen deficiency include dryness, irritation, and bloodshot eyes. D'wei Eye Care products are available to help keep your eyes healthy and well-oxygenated.

D'wei Eye Drops provide extra oxygen, helping maintain retinal health until normal blood flow is restored. These eye drops may increase oxygen levels in the blood, potentially causing dilation of the vessels in your retina. This could improve your eyesight.
