Abstract
An ophthalmic aqueous solution having an ionic salt ion content within the range 0.01% to 7.5% expressed as sodium chloride equivalents and comprising a non-ionic synthetic polymer such as polyvinyl alcohol and/or polyethylene glycol, and a non-ionic tonicity adjusting agent. The solution is effective in treating 'dry eye' conditions by causing a normalization of irregularly structured tears and at least retarding the precipitation of potein-like substances from the aqueous layers thereof.
