An aquatic mask comprises an outer mask structure (20 or 30) including one or more lenses, and an inner frame (10) suitable for containing ophthalmic corrective lenses. The outer mask structure (20 or 30) and the inner frame (10) include complementary formations (21 or 31 and 11 and 12) whereby the inner frame (10) can have a resilient push-fit engagement with the outer mask structure (20 or 30).
