The global prevalence of eye diseases continues to grow, bringing with it a reduction in the activity levels and quality of life of patients, and partial or complete blindness if left untreated. As such, there is considerable interest in identifying more effective therapeutic options and preventive agents. One such agent is vitamin D, known to have a range of anti-cancer, anti-angiogenic, anti-inflammatory and anti-oxidative properties, and whose deficiency is linked to the pathogenesis of a range of cardiovascular, cancer, and inflammatory diseases. This review presents the current stage of knowledge concerning the link between vitamin D and its receptor and the occurrence of eye disease, as well as the influence of analogues of calcitriol, an active metabolite of vitamin D. Generally, patients affected by various ocular disorders have vitamin D deficiency. In addition, previous findings suggest that vitamin D modulates the course of eye diseases and may serve as a marker, and that its supplementation could mitigate some disorders. However, as these studies have some limitations, we recommend further randomized trials to clarify the link between vitamin D and its activity with eye disease.

Consumer Labs summary on Vision Supplements - April 2019 (no mention of Vitamin D)
Lutein and zeaxanthin are believed to protect the macula of the eye (in the retina) from damage (see What It Does).
Many people consume relatively small amounts of lutein and zeaxanthin in their diets or have low levels of lutein in their blood; for them, taking a lutein supplement can slow the progression of age- related macular degeneration — although it won't improve the condition (see Getting lutein and zeaxanthin from food).
A dose of 10 mg of lutein appears to be better than a lower dose (6 mg). Higher dose products (e.g., 20 mg to 40 mg) are common, although it is not known if a higher dose is better. Nevertheless, 20 mg has been shown to be safe in a 6-month study.
It's not clear whether the "free" or "ester" form, or a natural or synthetic source, is better and it is not clear if there is added benefit with zeaxanthin.
Lutein and zeaxanthin at a reasonable dose (10 to 20 mg) can be obtained for as little about 15 cents per day (see What CL Found).
Other ingredients, particularly zinc, may be beneficial in slowing the progression of age-related macular degeneration. Vision formulas with these ingredients as well as lutein and zeaxanthin are available, although significantly more expensive than getting lutein/zeaxanthin alone. The formula with the strongest clinical evidence is Bausch + Lomb PreserVision AREDS Lutein (see What CL Found — Vision Formulas). One vision formula failed testing, containing only 9% of its listed lutein. To enhance absorption, it is best to take lutein and zeaxanthin supplements with a fatty meal. However, consumption of certain foods and supplements may decrease absorption of lutein and zeaxanthin (see Concerns and Cautions).
