RADIATION SHIELDING EYE MASK
An eye mask apparatus for protecting a patient's eyes during dental or other radiography (i.e., “x-rays”) has an eye covering portion including a lead vinyl sheet. The lead vinyl sheet has a perimeter configured such that the lead vinyl sheet can completely cover a patient's eyes. The eye covering portion includes a first side and a second side. A trim portion extends around the perimeter, with the trim portion extending inward over a portion of the first side and the second side. A retaining band is coupled to the eye covering portion at a first attachment point and a second attachment point. The retaining band is configured to hold the eye covering portion against the patient's eyes when the mask is worn.
