Low macular pigment optical density has been associated with increased risk of age-related macular degeneration, an important cause of vision problems in the elderly population. Dry eye is multifactorial disease of tears and the ocular surface associated with symptoms of dryness, grittiness, burning and redness of eyes. The risk of dry eye increases with age. The aim is to investigate the effects of sea buckthorn oil complemented with lutein on eye health, specifically on the macula.
