Vitamin A in HK Vitals Healthy Vision senses light for vision. Vitamin A is a precursor of rhodopsin pigment, which helps our eyes to see at night also. In addition to sensing light for vision, Vitamin A plays a crucial role in maintaining a healthy cornea, and its deficiency may lead to corneal dryness that causes discomfort to the eyes.
Macula is an important part of the retina that is involved in vision. Macular damage with age is one of the main causes of vision impairment and blindness. Lutein and Zeaxanthin in HK Vitals Healthy Vision are macular carotenoids that form the macular pigment of the eyes, which help control the age-related macular damage through their antioxidant and photoprotective action.
Blue light emitted by digital devices like computers, laptops, and smartphones has been implicated as a cause of digital eye strain. Blue light also readily penetrates through the cornea and the lens to reach the retina, leading to retinal damage. Lutein and Zeaxanthin help control digital eye strain and protect from the damaging effecting of blue light through their ability to filter blue light.
The retina is continually exposed to free radicals due to its rich blood supply, numerous mitochondria, and photons of light that strikes its surface. Vitamin C, Vitamin E, and lycopene help control free radical-induced retinal damage due to their potent antioxidant effects.
