This study presents a finite element analysis to model ocular biomechanics and the interactions between human eye contact lenses in closed-eye condition. The state, where eyelids are fully shut, challenges for experimental measurements due invasive nature of accessing analysing lens corneal interface, making simulation tools valuable accurate characterisation. primary objective this was examine how CLs fold twist their impact on cornea when is closed. secondary aim assess crucial parameters (Young’s modulus, base curve, diameter) influence stress distribution overall fit eye. findings show that increasing Young’s modulus significantly reduces promotes uniform distribution, it most influential factor wearer comfort safety. While curve diameter variations primarily affect area, minimal. research provides insights improving design enhancing safety wearers.

A meta-analysis was conducted to assess the evolution of, applications and recent advancements in materials surface treatments for contact lenses. This study aimed comprehensively synthesize available data, focusing on innovations that enhance vision correction, comfort, safety while emphasizing sustainability as a critical factor future development. Registered with PROSPERO, this analysis adhered PRISMA AMSTAR-2 guidelines. systematic review of databases including PubMed, Web Science, Scopus performed studies published between 2019 2024, without language restrictions. Observational optical lens were included, random-effects model used address high heterogeneity among included studies. From nine analyzed, significant identified regarding functional properties treatments. Key technologies like self-lubricating lenses reduce friction, nanogels prolonged therapeutic drug delivery, coatings minimize protein lipid deposition, ensuring greater comfort extended wearability. Additionally, biodegradable eco-friendly underscore industry’s commitment reducing environmental impact lenses, addressing challenges related disposal recycling. These highlight potential integrating improvements sustainability, paving way more effective environmentally responsible
