Business providing opticians/optometrist/audiologist services may provide appointments for essential emergency treatment, but routine check-ups must cease with immediate effect. Wherever possible, appointments should be pre-booked. If you do open your business then you must ensure that you put in place measures to ensure that social distancing of both your workforce and customers is maintained as practicably as possible. You must also ensure adherence to hygiene guidelines and are strongly advised to wear face coverings. You should only travel to and from your place of work to provide those services.
