Applying kajal to the eyes of newborns and toddlers is a common practice in many parts of India, believed to ward off the evil eye and enhance the beauty of the eyes. However, this practice can pose significant risks to the health of the child’s eyes. Commercially available kajals often contain high levels of lead and other harmful chemicals, which can be toxic when absorbed through the mucous membranes of the eyes. Even homemade kajal, which is perceived as natural and safe, can be contaminated with lead from the environment during its preparation. Lead exposure in infants is particularly dangerous as it can lead to neurotoxic effects, including reduced cognitive development and behavioral issues. Additionally, kajal can block the delicate tear ducts of babies, leading to infections, irritation, and discomfort.

The pediatric and ophthalmological communities strongly advise against the application of kajal to infants’ eyes. The immature eye structures of infants are particularly susceptible to irritation and infection. The use of kajal can introduce foreign particles and pathogens, leading to bacterial conjunctivitis and other eye infections, which can be severe and may threaten vision if not treated promptly. Moreover, the habit of touching and reapplying kajal can further introduce germs from the hands into the sensitive eye area. Instead of using kajal, maintaining good hygiene and regular pediatric check-ups are safer and more effective ways to ensure the health and well-being of a child’s eyes.
