The eye region is sensitive and thus needs products that are equally safe and aesthetically enhancing. Eye cosmetics like mascaras, eyeliners, and eyeshadows enhance look but should pass stringent dermatological and ophthalmological tests to o avoid irritating, allergy, or damaging tear film stability. Main testing areas are skin and eye irritation, microbial contamination, and long-term compatibility with sensitive periorbital tissues.Some colored or clear contact lenses have functional or cosmetic advantages. Whereas clear lenses only correct vision, colored ones enhance an individual’s appearance by changing the color of the eye. They also need to comply with strict biocompatibility tests for issues such as dry eye, corneal abrasion, or infections. The assessments focus on their oxygen permeability, wettability, and microbial resistance. In colored lenses, non-toxic pigments have been investigated to ensure they do not in any manner interfere with lenses proper functionality or eye health. Safety also must address possible interactions between lens and eye cosmetics, thus ensuring the compatibility of the products to be used by lens wearers.The test utilizes several advanced techniques, numerous in-vitro reconstructed human cornea models, irritation assays (HET-CAM), and in-vivo tear film evaluation. The inclusion of functionality, safety, and aesthetic in these tests gives support to the development of groundbreaking safe eye cosmetics and contact lenses that further ensure the consumer’s wellbeing.
