Abstract
The present invention is directed to a lubricant for contact lenses or dry eye or to provide relief from eye irritation. In particular, the composition contains a biguanide preservative in combination with polyvinylpyrollidone. An ophthalmic solution containing such a combination of components can be applied, in the form of droplets, to the eye or to contact lens in the eye. In one embodiment of the invention, the composition is used as a universal lubricant, meaning that the same solution can be used with or without contact lenses, depending on the needs of the user, whether in the context of a contact-lens care or general eye care.
