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.
In addition to atheletes, pilots could benefit from foods high in lutein and zeaxanthin.
A Dietary Strategy for Optimizing the Visual Range of Athletes
Higher dietary intake of lutein/zeaxanthin may translate to better distance vision and field performance in athletes.Visual range is quantified by assessing how far one can see clearly (an ability crucial to many athletes). This ability tends to vary ...

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.
