Visual range is quantified by assessing how far one can see clearly (an ability crucial to many athletes). This ability tends to vary significantly across individuals despite similar personal characteristics. We hypothesize that the primary driver of these differences is the individual response to scattered short-wave light in the environment moderated by the dietarily derived retinal pigments lutein and zeaxanthin.

Key Points​

• Two specific carotenoids (lutein and zeaxanthin, L and Z) are known to be particularly important to nervous system health, in general, and visual-motor performance.
• Empirical data have shown that these pigments can improve chromatic contrast, decrease glare disability/discomfort, and speed recovery from photostress.
• This review focuses on the effects of L and Z on seeing objects in the distance (visual range) particularly under adverse conditions (such as interference by blue haze).

In addition to atheletes, pilots could benefit from foods high in lutein and zeaxanthin.

Le Marchand and colleagues (31) studied the dietary habits of indigenous Fijians and found that their average intake of L and Z was approximately 24,000 mg/d. This is contrasted with the common American diet where L and Z intake is approximately 1000 μg/d (26).

I haven't tried this

Listener asks how to not need eyeglasses. Ginger eye washes. 15 slices of ginger, 1.5 cups water, simmer 10 minutes, strain. Refrigerate for up to 4 days. Add 1 tsp. ginger solution to 1 cup distilled water. Do eye washes 2-3x/week.
