There has been a recent focus on hygiene as a measure to protect from and reduce the spread of COVID-19. Contact lens wearers have been advised that if they are healthy, they can continue to wear their lenses provided that they continue to practise good hygiene. This includes washing hands in accordance with recommended guidelines for a minimum of 20 seconds with water and soap and drying hands before handling lenses and touching the face. Although this might be considered common knowledge, a recent survey has found that up to 44% of people do not wash their hands before inserting contact lenses (Fonn, D. and Jones, L. Hand hygiene is linked to microbial keratitis and corneal inflammatory events. Contact Lens Anterior Eye. 2019; 42: 132–135). It is also important to remember and continue practising regular lens hygiene, including wearing disposable lenses only once, disinfecting reusable contact lenses and avoiding overnight wear unless prescribed.
Where contact lens wearers have been infected with COVID-19 or are feeling unwell, they should cease wearing contact lenses. Recent studies have indicated that in a small amount of cases, COVI-19 can cause conjunctivitis (Xia, J., Tong, J., Liu, M., Shen, Y., and Guo, D. Evaluation of coronavirus in tears and conjunctival secretions of patients with SARS‐CoV‐2 infection. J Med Virol. 2020)
