Contact lens blister package

A blister package assembly comprising:

• at least two base members separate from one another, each base member comprising (i) a cavity containing a contact lens in a contact lens packaging solution and (ii) a planar surface region surrounding the cavity;
• and
• a seal member affixed to the planar surface region of each base member to form a seal and thereby contain the contact lens and the packaging solution in the cavity;
• wherein
• for each pair of adjacent base members, the seal comprises:
• for each base member, a first seal region extending around the whole of the perimeter of the cavity and extending from an inner edge of the seal, the first seal region having a substantially constant width, wherein the width of the first seal region is the minimum perpendicular distance between the inner edge of the seal and an opposing outer edge of the seal around the cavity, the first seal regions of the pair being spaced apart;
• and
• at least one second seal region, each second seal region interconnecting the first seal regions of the pair along a first axis;
• the each second seal region having a length, being the minimum extent of the second seal region between the first seal regions in a direction parallel to the first axis, and a width, being the extent of the seal in a direction perpendicular to the first axis, and wherein the length of the second seal region is at least a third of the minimum width of the second seal region.
