Whitaker Nutrition is promoting a supplement they call Vision Essentials Ultra, which has lutein 40mg, zeaxanthin 6 mg, and meso-zeaxanthin 2 mg, in addition to vitamins A and C, zinc, copper, bilberry extract, saffron extract, and glutathione. How does this supplement compare in benefits for eye health to the supplement OcuXanthin, which has hyaluronic acid 50 mg, lutein 10 mg, astaxanthin 6 mg, and zeaxanthin 2 mg?

There is research suggesting that astaxanthin promotes accumulation of zeaxanthin in the retina. Is that at least one reason that inclusion of astaxanthin would be beneficial? What else is important for us to know?

According to research findings, different zones within the macula have lutein, zeaxanthin, and meso-zeaxanthin, exclusively, suggesting unique roles. It is unclear whether dietary uptake of meso-zeaxanthin or its conversion from zeaxanthin within the eye is its natural source. How important is taking meso-zeaxanthin along with zeaxanthin as a supplement for eye health?

Many critics of intelligent design point to examples of obvious imperfections, such as the location of neural connections being in front of the photoreceptor cells, rather than behind the retina, and the formation of a blind spot because the neural wiring to the brain must poke through the retina to form the optic nerve. Why do these seeming errors exist?

Researchers at Harvard University have shown that over time, prolonged exposure to blue light can cause damage to the retina at the back of the eye, which may lead to age-related macular degeneration (AMD) and possibly other serious health and vision problems. How significant a health problem is spending time watching cell phone, tablet, and computer screens?
