With aspherical design of the front surface of the new lenses Pure Vision practically eliminate spherical aberration, thereby improving the quality of vision. The lens also has become much more comfortable – due to the improved smoothness of the surface and a lower modulus of elasticity, which decreased by 28%. (more…)
Yet the absence of injury – this is not all that includes the issue safe wearing contact lenses.Moreover, the likelihood of injury is not as crucial in assessing the health safety, the likelihood of complications and diseases that could result from this type of vision correction, which may be due to low transmission of oxygen to the cornea,lack of stability to the sediments and the low wettability of the lens surface.In order to assess the following factors associated with safe wearing of contact lenses, imagine this situation: the family is sent in the evening in a car for shopping or at dusk returning home after the weekend, a nice outdoors.And here an important role in whether contact lenses are safe for family members in this situation, play their optical characteristics and design of which depend on the degree of visual acuity, for example, that a family member who has a car, at any time of day and night, in any light.

Can I meet the visual needs of all of these patients with contact lenses?
