Prevention of diagnostic lens fogging: A challenge

Abstract

Pandemic of COVID-19 brought multiple professional and personal challenges to every individual. Ophthalmologists faced fogging of diagnostic lenses due to patients wearing facemasks during clinical examination leading to unreliable clinical findings. India being a developing nation, the patients visiting the outpatient department (OPD) of government hospitals have ill-fitting masks which increases the problem of fogging. We describe a simple technique for the prevention of lens fogging in routine OPD practice.
