The study of life in addition to a study on the subject of free fuel. To learn the parameters of the lens, such as the refraction curve radius. The diameter of the lens features an external touch condition. The frozen lens cleaners exposed Leakage of the container
Education lifespan addition to education on the subject of sterile ago. Also to study the various parameters Of contact lenses such as refractive power Radius Diameter The appearance of contact lenses The soaking liquid lenses Leaking containers
Study on lifetime than studies in of sterility. Also need to study the parameters of contact lenses, such as the refracted. Curvature radius, diameter of external characteristics of contact lenses.Leakage of the container.
