Abstract

Rationale- These days, due to ozone layer breakdown and global environmental condition, human exposure to electromagnetic radiation, especially UVR and IR rays are increasing day by day. Ultraviolet rays and infrared rays have large public health complications and because of this U.V. and IR rays- related ocular diseases are to be expected. In Ayurveda Classical text, the loss of vision (Darshannasha) due to seeing god, sage, Gandharva, very large snakes, and the sun, has also been described by Acharya Sushruta and termed it as ‘Animittaja Lingnasha’. In context to Nayanabhighata, Acharya Videha has described Atapa (sunlight) and Surya as a causative factor in causing ocular injuries and symptoms like redness, burning sensation, pricking type pain, inflammation, suppuration etc. So as per Ayurveda, the impact of radiation especially UV and Infrared rays on the eyes can be a resemblance to these states of Acharya Sushruta & Acharya Videha. In allopathy, there are no treatment options for the prevention and care of this pathology except the use of spectacles, contact lenses, goggles, eye shields, intraocular lenses, and gas permeable hard lenses, helmets consisting of absorptive or reflective filters to manage the unwelcomed radiation. But in Ayurveda there are many procedures like Parisheka, Nasya, Tarpana, Putapaka, and Anjana etc. which are used for the prevention of this pathology and maintaining the eyes in a healthy state. These procedures restore the normal osmolarity of tears which help in nourishment and rejuvenation of the ocular surface and make the eyes tolerant of wind and sunlight. Background- The course of energy with the speed of light when travels through an empty space or a medium forms a electric and magnetic fields that forms electromagnetic radiation such as radio waves, visible light, and gamma rays. The objects present within the field of vision reflects the light into the eyes. Even though having a broad spectrum, only a small range of light is visible to the human eye. The visible spectrum range extends from 400 - 700 nm. Beyond the long end, there are infrared (heat), radar, and radio waves. Beyond the short end, there are ultraviolet (UV), X-ray, and cosmic waves. Outcome- To assess the relationship between radiation and its hazardous effects on various ocular media and explore the contribution of Ayurveda to prevent and minimize the effect of radiation on the eye.
