Kajal (kohl) ... and your eyes

‘Kajal’ (Kohl) is a popular eye care product and its use has been reported since ancient times. Kohl (surma) has been defined as an eye preparation in ultra fine form of specially processed “Kohl Stone” (galena) incorporated with some other therapeutically active ingredients. there are lots of myths associated with kajal use. It has been claimed to keep the eyes cool and clean, improve vision and strengthen the eyes. It has also been used for the prevention and treatment of eye diseases such as blepharitis, cataract, conjunctivitis etc. It is also said to ward off an ‘evil eye’. My experience as an eye specialist is contradictory.

As an eye specialist, I see a lot of kajal associated chronic eye allergies, infections/chronic conjunctivitis, uneven conjunctival surface, chronic dryness, kajal deposits on under lid surface. Eyes often give a bleary, tired, congested and murky off white appearance with discharge in corners which is not beautiful…!!!

Most people believe that home- made kajal is very safe, good for eyes.

Home-made kajal of any kind…badam, oil, ghee or herbs, is finally burnt carbon preparation on which bacteria grow within 6 hours. No wonder regular application of any such preparation leads to chronic infections.

Most commercially produced ‘kajal’ contain high levels of lead. Studies have revealed that ‘Kajal’ comprises of galena (PbS), minium (Pb3O4), amorphous carbon, magnetite (Fe3O4), and zincite (ZnO). Prolonged application may cause excessive lead storage in the body, affecting the brain and bone marrow, causing convulsions and anemia.

Dirty fingers, sharp and uneven fingernails of the caregivers are potentially harmful to the child’s eyes. I distinctly remember two kids with corneal ulcers and losing good vision, post regular kajal applications from periphery.
