Blue light is short-wavelength visible light with high energy. Excessive blue light can cause irreversible damage to retinal cells through photo-oxidation and the formation of reactive oxygen species (ROS). Blue light is almost everywhere. In addition to sunlight, a large number of blue light from electronic devices (such as mobile phones, tablets, laptops, etc.) and indoor lighting have increased the chance of people being exposed to blue light.
Fortunately, the human eye's retinal tissue contains many antioxidant enzymes and antioxidant molecules including lutein and zeaxanthin, which help reduce potential damage caused by blue light exposure. The macular pigment formed by lutein and zeaxanthin can effectively filter blue light, thereby improving visual function and contrast sensitivity, improving glare tolerance, and reducing glare recovery time.
Lutein and zeaxanthin are selectively deposited in the macula of the retina to protect the eyes and improve visual function. However, the human body cannot synthesize lutein and zeaxanthin on its own, and must be ingested from the diet.
YT Biochem provides bulk order of lutein and zeaxanthin. If you are committed to researching health products that are good for eyes, lutein and zeaxanthin are good choices. Welcome to send us an inquiry if you have any interests.
