Lens Technology

Contact lenses are considered as an advanced medical devices, worn to correct vision or for cosmetic or therapeutic reasons, compared with spectacles, contact lenses enable more ease of wear during sports and leisure activities by providing a wider field of view, less chance of dislodgement, less susceptibility to fogging, slipping off the face due to sweating, and dirt. Contact lenses also allow sunglasses and protective eyewear to be worn on top without any hassle. Contact lenses typically provide better peripheral vision, and do not collect moisture. Eventually, Glaucoma patients could potentially insert drug-dispensing contact lenses rather than taking the eye drops repeatedly.
