I know of a candidate (who was on my CBAT sitting) who passed his medical/ophthalmic test for WSOp albeit with specs!
I certainly hope this doesn't come across ignorant by any means, but say in the case of a WSOp candidate (with specs) passing his generic at 45(R) - would the specs potentially hinder rotary compared with another candidate who doesn't require corrective eyewear?
Best regards.
