A 70 year old lady presents with reduced vision in her right eye. While wearing her distance glasses, with her left eye occluded, at 6 metres away from the Snellen chart she cannot see the top letter, an ‘X’ with a small numeral next to it that reads ‘60’. You move her to 3 metres away, at which point she accurately reads this top letter. How do you record her right eye visual acuity?
