摘要：
A composition comprising xanthophyll carotenoid mesozeaxanthin (MZ) for use as a dietary supplement or food additive for oral consumption for improving the visual performance of a human subject, in particular, a human subject not experiencing age-related macular degeneration (AMD). Visual performance may be assessed by measuring one or more of spatial contrast sensitivity function, (best corrected) visual acuity, glare disability, discomfort glare, ocular straylight, photostress recovery and S-cone sensitivity. The composition may also comprise lutein and/or zeaxanthin. A preferred combination is MZ/lutein/zeaxanthin in the ratio 10:10:2. Additional components may include one or more vitamins and/or minerals； a vegetable oil, fish oil and/or omega 3 fatty acid. The composition may be in the form of an egg obtained from a hen fed with a feed comprising MZ. A method of preparing the composition comprising the step of mixing an effective amount of MZ with an acceptable dietary diluent, excipient or carrier is also claimed.
