Coronavirus: Can it affect eyesight?

Dominic Cummings has faced a media grilling over his decision during lockdown to drive his family 260 miles to his parent's property in Durham.

But if the front of the pupil and the iris (the coloured part of the eye), is also affected, there can be some blurring of vision.

Prof Robert MacLaren, an eye expert at the University of Oxford, said a recent study in Wuhan, China, where the coronavirus outbreak began, reported a range of eye problems, including swelling and sticky eye.

"Any of the above symptoms may affect vision and affected patients would be advised to drive with caution or not at all if there was significant blurring of vision or double vision," he sRead More – Source
