        <p>Among five sense organs or <italic>Gyanendriyas</italic> &#x2018;Eyes&#x2019; are considered as most important sense organs. They are said to be the path to mind and seat of <italic>Tejas</italic> (Light). Now a days due to their overuse and negligence in maintenance we are facing many eye related problems like Dry Eye Syndrome, Cataract, Age related Macular Degeneration, Glaucoma, Computer Vision Syndrome etc. To observe the association of defective lifestyle and related eye problems with their preventive measures, different Ayurvedic procedures are reviewed from ancient literatures and some modern researches. <italic>Dinacharya</italic> (Daily regimen) explained in Ayurveda helps to prevent many derangements. Lifestyle modification in terms of proper daily regimen and dietary regimen could help to prevent eye problems. <italic>Padabhyanga</italic> (foot massage) is one of the procedures mentioned in <italic>Dinacharya</italic>, an effective therapy for healing of eye disorders.</p>

      <title>﻿INTRODUCTION</title>
      <p>Ayurveda, is the most ancient remedial under human passion and serving us since Vedic periods. &#x201C;Swasthasya swasthya rakshanam aturasya vikara prasamanm cha&#x201D; (Charak Samhita Sutrasthana 30/26) explains the aim of Ayurveda, to preserve health of healthy person and to cure the diseased one. Here we can observe the prime importance of preservation of health of a heathy person. This can be achieved by preventing diseases and promoting health through healthy lifestyle. In the same way Prevention of Eye disorders and promotion of eye health is essential. Among all sense organs eyes are of prime importance as the vision is very crucial interpreter for social, spiritual and intellectual development of human beings. Vagbhatacharya rightly quoted the importance of eyes, &#x201C;Once the vision is lost, the whole world will become only one kind that of darkness&#x201D; (Ashtanga Hridaya Uttarasthana 13/98). Changing lifestyle, pollution, excessive use of computer, mobile phones, irregular sleeping habits, improper daily regimen and seasonal regimens have resulted in many eye problems and brought miseries in daily life. Diseases like Glaucoma, Cataract, Computer Vision Syndrome, Dry Eye Syndrome, Age related Macular Degeneration, Diabetic Retinopathy, Hypertensive Retinopathy etc. may occur due to defective lifestyle. Ayurveda gives a complete remedy to prevent the eye problems by simple daily procedures like, <italic>Netraprakshalana</italic> (washing of eye), <italic>Anjana</italic> (Collyrium), <italic>Nasya</italic> (Nasal instillation), <italic>Snana</italic> (Bath), <italic>Nidra</italic> (Sleep), <italic>Padabhyanga</italic> (Foot massage), proper dietary regimen etc. Various eye exercises and yogic practices are also helpful.</p>

      <title>﻿ETIOLOGY OF EYE DISORDERS</title>
      <sec id="s3a">
        <title>I. Improper dietary habits</title>
        <p>﻿According to Acharya Sushrut, Excessive intake of <italic>Amla</italic> (Sour), <italic>Shukta</italic> (Vinegar), <italic>Aranala</italic> (Sour gruel), <italic>Kulathi</italic> (<italic>Dolichos biflorus</italic>), <italic>Masha</italic> (<italic>Vigna mungo</italic>) is the cause of eye disorders (Sushrut Samhita Uttaratantra 1/26-27). Various modern studies show, intake of high fatty diet may result in atherosclerosis of choroidal blood vessels and increase more risk (80%) of Age-related Macular degeneration (AMD) (<xref ref-type="bibr" rid="r014">Seddon JM <italic>et al</italic>., 2001</xref>). High sugar diet or higher dietary carbohydrate may affect eye sight and increase risk of cataract (<xref ref-type="bibr" rid="r006">Lobefalo L <italic>et al</italic>., 2011</xref>). Less dietary intake of Vitamin-A may lead to loss of vision (most common cause of blindness in world), night blindness, dryness of eye etc. It also increases risk of cataract (<xref ref-type="bibr" rid="r020">Wang A <italic>et al</italic>., 2014</xref>). Decreased dietary intake of Vitamin- E and Zinc make vulnerable to destruction of cell membranes through oxidative change and may increase the risk of blindness (<xref ref-type="bibr" rid="r013">Rasmussen H <italic>et al</italic>., 2013</xref>).</p>

        <title>II. Improper daily habits</title>
        <p>﻿Acharya Sushrut has mentioned <italic>Swapna Viparyaya</italic> (Reversing the usual sleeping habit) viz disturbed sleep, decreased sleep, day sleep and night awakening give more strain to eyes ﻿(Sushrut Samhita Uttaratantra 1/26-27). Also, different studies claim sleep disturbance to be an influencing factor on DED (Dry eye diseases) (<xref ref-type="bibr" rid="r009">Kawashima M <italic>et al</italic>., 2016</xref>). Ayurveda claims indulgence in <italic>Dhumapana</italic> (Smoking) results in eye problems (Sushrut Samhita Uttaratantra 1/26-27). Modern studies also claimed that Smoking would be expected to result in a higher incidence of diabetic retinopathy as it leads to increased platelet aggregation and adhesiveness and tissue hypoxia, factors hypothesized to be involved in the pathogenesis of diabetic retinopathy. (<xref ref-type="bibr" rid="r010">Klein, B. E <italic>et al</italic>., 2007</xref>). Observations in many studies have indicated a role for smoking in the incidence and progression of AMD (<xref ref-type="bibr" rid="r019">Thornton J <italic>et al</italic>., 2005</xref>).</p>

        <title>III. Environmental factors</title>
        <p>﻿According to Acharya Sushrut excessive exposure to dust, smoke, dirty water, sudden change in temperature etc. may cause irritation in eyes (Sushrut Samhita Uttaratantra 1/26-27). Light exposure, especially in the UV-B light range, has been examined and found to be a risk factor for cataract in some studies (<xref ref-type="bibr" rid="r005">Asbell PA <italic>et al</italic>., 2005</xref> &#x26; <xref ref-type="bibr" rid="r018">Taylor HR, 1988</xref>)</p>

It is also seen that chronic stress increases level of Adrenaline and in other hand this adrenaline increases risk of Glaucoma by increasing intra ocular pressure (<xref ref-type="bibr" rid="r016">Shily BG <italic>et al</italic>., 1987</xref>).</p>

          <p>﻿Counseling contributes a main role towards the prevention.

        <p>﻿Acharya Vagbhat identified 4 major <italic>Nadis</italic> (Channels or nerves) in feet which connect to eyes, help to maintain good eyesight and relieve eyestrain when subjected to soothing therapies like <italic>Padabhyanga</italic> (Astanga Hridaya Uttarasthana 17/66). <italic>Padabhyanga</italic> pacifies the <italic>Doshas</italic> (The three basic elements of body <italic>Vata, Pitta</italic> and <italic>Kapha</italic>) through the <italic>Nadis</italic> reaching the Netra thereby nourishing and soothing them.</p>
        <p>﻿Two <italic>Nadis</italic> (Channels or nerves), <italic>Gandhari</italic> (which connects left great toe to left eye) and <italic>Pusha</italic> (which connects right great toe to right eye) described in Yoga <italic>Shastra</italic> (Yogic science). Oil gets absorbed percutaneously through skin and ﻿nourishes eye through these <italic>Nadis</italic> (<xref ref-type="bibr" rid="r004">Acharya RJ, 1997</xref>).</p>
        <p>﻿According to Bhela Samhita, <italic>Alochaka Pitta</italic> present in the eyes, and as per other references <italic>Alochaka Pitta</italic> is present in the <italic>Pada. Padabhyanga</italic> stimulates the <italic>Alochaka Pitta</italic> and enhance the visual acuity.</p>
        <p><italic>﻿Sparshanendriya</italic> (skin) is known as <italic>vyapak indriya</italic> (covers all other sense organs) as it is spread over all other <italic>indriyas</italic> (sense organs) and <italic>Vata</italic> (one of important elements of ‘<italic>Tridosha</italic>’ or the three basic elements) is found predominantly in <italic>Sparshanendriya</italic> (skin). <italic>Padabhyanga</italic> through its <italic>Vata</italic> ameliorating action is responsible for better functioning of all <italic>indriyas</italic> including <italic>chakshuindriya</italic> (Charak Samhita sutrasthana).This absorbed <italic>Taila</italic> (oil) through these <italic>Strotas</italic> or <italic>Nadis</italic> (Channels or nerves), acting by its <italic>Snigdha</italic> (unctuous) and Ushna (hot in potency) properties pacifies <italic>Vata Dosha</italic> in the eyes aggravated by <italic>Atiyoga</italic> (over use) or <italic>Mithyayoga</italic> (improper use) of <italic>Netra</italic> (i.e. Eye Strain).</p>
        <p>﻿Related researches revealed that by <italic>Padabhyanga</italic> the somatic sensory area in the cortex may get stimulated and as areas of feet and eyes are same i.e. Area II of cortex, its stimulant effect may improve the function of eyes by reducing the eye strain (<xref ref-type="bibr" rid="r012">Rashmi K <italic>et al</italic>., 2015</xref>). The interpretative (association) areas of feet and eyes meet at Wernicke’s area and <italic>Padabhyanga</italic> by nourishing or stimulating effect of <italic>Padabhyanga</italic> improves the function of eyes (<xref ref-type="bibr" rid="r008">Joshi N. <italic>et al</italic>., 2016</xref>). <italic>Padabhyanga</italic>, normalizes the two important neurotransmitters Serotonin and Norepinephrine, which regulates a wide variety of Neuropsychological processes along with sleep Thus it induces relaxation and natural sleep and impacts a positive effect on eyes (<xref ref-type="bibr" rid="r008">Joshi N <italic>et al</italic>.,2016</xref>).</p>

      <title>﻿CONCLUSION</title>
      <p>Adoption of modern lifestyle affected ocular health and brought miseries to human society. Ayurveda, the ancient medical science gives a ray of hope to overcome these problems. A healthy lifestyle with proper maintenance of daily regimen, dietary habit and avoidance of exposure to causative factors would be helpful towards better eye health. <italic>Padabhyanga</italic> a simple daily procedure can bring a magical remedy for prevention of various eye disorders. The &#x201C;Vision 2020: Right to Sight&#x201D; can be fulfilled by proper counseling and encouragement of general public to observe the above simple preventive and promotive eye care measures.</p>
