Introduction to contact lens.ppt
Leonardo Da Vinci proposed the first idea for a contact lens in 1508 as a water-filled globe to correct refractive errors. Subsequent developments led to the first glass contact lens made by F.A. Muller in 1887. Adolf Fick placed the first scleral contact lens on a human eye in 1888. Modern contact lenses are made of plastics like PMMA, silicone, and hydrogels. Contact lenses provide better optical qualities than glasses and come in various materials, designs, and correction types to fit different eye conditions and prescriptions. Complications can include corneal edema, vascularization, and infections if not cared for properly.
