Blindness comes with devastating physical condition and deep socio-economic implications. Approximately 45 million people in the world are blind and another 135 million people are deemed to be visually disabled by 2020. 鈥榁itamin A鈥� deficiency alone accounts for 6% among the causes of blindness. It is the chief cause of Childhood Blindness in developing countries. As a step towards prevention of blindness, the 鈥楴ational Programme for Control of Blindness鈥檙ecommends a single massive dose of 2,00,000IU of 鈥榲itamin A鈥� orally every 6 months to preschool children and half the dose to children between 6 months to 1year of age. But, these 鈥榬etinol form鈥檖rophylactic supplements in excess may lead to toxicity causing acute and chronic symptoms, birth defects and even death. Ayurveda as a science has an equal responsibility in protecting 鈥榬ight to sight鈥� of each individual. Though the classical references does notdirectly mention about the daily dose of the nutrients, all the drugs mentioned as chakshushya, such asGarjara, Karavellaka, Draksha, Shigru, Paalankikaetc do contain a large amount of 鈥榲itamin A鈥� in them. Hence an attempt has been made in this article to quantify these classical chakshushyadravyafor daily recommended need of 鈥榲itamin A鈥� to every individual.
