In this review, the current evidence related to the ocular transmission of SARS-CoV-2 and its common manifestations was studied. According to this review, 7% to 69.4% of patients had at least an ocular symptom following COVID-19. Ocular symptom are bilateral or unilateral conjunctivitis, increased secretion, eye itching and foreign body sensation, epiphora, dry eye, conjunctival congestion, eye pink, conjunctival hyperemia, and chemosis. SARS-CoV-2 particles were found in tears and conjunctiva. Therefore, the transmission of COVID-19 by conjunctiva is possible. Then, it is essential to wear eye shield to protect against developing ocular involvement by COVID-19 because personal glasses and contact lenses cannot protect from COVID-19.
