Tṛphalā ghṛta is described by Ācārya Vāgbhṭa in the management of myopia (Dabhi et al. 2016). Tṛiphalā ghṛta, which is generally used for tarpaṇa (eye bath), is saturated with a decoction of the triphala group of drugs (Emblica officinalis, Terminalia belerica, Terminalia chebula), and hence it contains both lipid and water-soluble constituents of triphala. Thus, it has lipophilic as well as hydrophilic properties. Therefore, it penetrates well through various layers of the cornea. In this way it is effective in computer vision syndrome and Stargardt’s macular degeneration (Mohan 2013; Sawant et al. 2013; Sreekumar and Nair 2017).
A-Z of Standardisation, Pre-Clinical, Clinical and Toxicological Data
Published in Saroya Amritpal Singh, Regulatory and Pharmacological Basis of Ayurvedic Formulations, 2017
Computer vision syndrome: In a clinical study, 151 patients were registered, out of whom 141 completed the treatment. In Group A, 45 patients had been prescribed Triphala eye drops; in Group B, 53 patients had been prescribed the Triphala eye drops and Saptamrita Lauha tablets internally, and in Group C, 43 patients had been prescribed the placebo eye drops and placebo tablets. In total, marked improvement was observed in 48.89, 54.71 and 06.98% patients in groups A, B and C, respectively (Gangamma and Rajagopala 2010).
All health begins at home in the community
Published in Ben Y.F. Fong, Martin C.S. Wong, The Routledge Handbook of Public Health and the Community, 2021
Electronic devices are essential to modern living. Whilst they provide mankind with much convenience and enjoyment, they are also hidden danger to our physical and psychological health if not used appropriately and with caution especially amongst young children. Parents should bear the responsibility in showing the children the proper use of these devices in the home environment. Computers and portable mobiles are becoming an indispensable component in children’s life and may affect their sleep duration and quality (Carter et al., 2016). Very often children tend to eat snack food with high sugar and calories when they sit down to play video and computer games. Healthy eating habits are sometimes disrupted by these electronic devices, leading to childhood overweight and obesity. Prolonged usage of electronic devices may result in the Computer Vision Syndrome and other vision-related problems such as dry eyes, eye strain, blurred vision, etc. (Department of Health, 2014). Furthermore, undesirable adverse effects affecting teenagers are known to be caused by the addiction in using the electronic devices. They include poor performance at school, absenteeism, problematic interpersonal relationships and antisocial behaviours (Kwong & Fong, 2019). Internet addiction has become a modern-day epidemic in the developed world, affecting practically everybody of all ages and having much more long-term adverse health effects to youngsters. Although it is challenging to most parents, it is definitely worthwhile to spend the effort to teach and frame the proper use of electronic devices among children while they are growing up at home. Once the golden period of learning to control one’s desire in sticking onto electronic devices has gone, the result could be devastating.
Ocular surface predisposing factors for digital display-induced dry eye

Prolonged digital display use has been associated with several eye and vision problems. These eye-related complaints have been grouped under the term ‘computer vision syndrome’.3 One of the main symptom categories of computer vision syndrome is related to dry eye and encompasses symptoms of irritated or burning eyes, ocular dryness, tearing, eye discomfort or foreign body sensation, amongst others.4 Substantial research advises of an increased prevalence of dry eye signs and symptoms amongst digital display users.5–10 Ocular surface and tear film abnormalities, including reduced tear stability, alterations in tear volume and tear composition, increased oxidative stress, ocular surface inflammation and even meibomian gland dysfunction have been found in computer users.7–11 Accordingly, the Tear Film and Ocular Surface (TFOS) Dry Eye Workshop (DEWS) II Epidemiology Report has listed digital display use as a consistent risk factor for dry eye disease (DED), which may explain the surprising relatively high prevalence rates of DED reported in younger subjects (20-40 years).12

The excessive use of electronic devices is known to cause the Computer Vision Syndrome (CVS) defined as a group of eye- and vision-related symptoms that result from prolonged use of computer, tablet, e-reader and cell phone.1–3 Previous studies reported the high prevalence of the CVS and evaluated risk factors of CVS among university students and workers heavily dependent on computers.3,4 Reddy et al. reported the prevalence of the CVS of 89.9% among university students,5 while Logaraj et al. reported the prevalence of the CVS of 81.9% among engineer students and 78.6% among medical students.6 Poudel et al. reported that the prevalence of the CVS was 82.5% among IT office workers,7 and Assefa et al. found that the prevalence of CVS was 73.0% among bank workers who spent most of time in screen.8 While the intensive use of electronic devices for educational or recreational purposes are very common among young children, the prevalence of the CVS in school children has not been studied.
Ocular and systemic melatonin and the influence of light exposure
Published in Clinical and Experimental Optometry, 2019
Yellow‐tinted lenses, which filter short wavelength blue light, have traditionally been used to improve contrast. More recently, evidence suggests that night‐time wear increases melatonin and improves sleep, as discussed above. With increased interest in potential damaging effects of blue light to the retina, the use of blue‐blocking lenses, both in spectacles and intraocular lenses, has been increasing.2011 Specifically, studies in animal models and in vitro cell cultures have shown that prolonged exposure to high‐intensity light in the short wavelength spectrum can induce phototoxic retinal damage, raising concerns that cumulative exposure to short wavelength light in humans may induce retinal toxicity.2017 Additionally, blue‐blocking lenses are widely marketed as a strategy to alleviate computer vision syndrome, also known as digital eye strain, which is a group of vision‐related problems resulting from extended electronic device use. These types of blue‐blocking technology are promoted for full‐time wear in habitual spectacles; however, long‐term effects on circadian patterns, melatonin, and in children, eye growth, are unknown.
