Vision correction is a field of research that focuses on developing methods and technologies to improve or correct visual impairments such as nearsightedness, farsightedness, astigmatism, and presbyopia. This area of research includes the development of eyeglasses, contact lenses, and surgical procedures such as LASIK to improve the clarity of vision and overall visual acuity in individuals with these conditions. Researchers in this field work to understand the underlying causes of visual impairments and to develop more effective and efficient methods for correcting them. The goal of vision correction research is to provide individuals with better vision and improved quality of life.
