The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.

The present invention relates to a lens care solution having 0.001 to about 5 weight percent of a low molecular weight amine of the general formula: ##STR00001## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or low molecular weight radicals, and R.sub.5 is a low molecular weight radical, or salt thereof; an effective amount of a tonicity agent; and the balance water.

The present invention relates to an ophthalmic solution comprising 0.00001 to 10.0 weight percent of a simple saccharide, at least 0.00001 weight percent of a preservative, and not more than about 0.2 percent by weight chloride. The simple saccharide is chosen from the group consisting of: inositol; mannitol; sorbitol; sucrose; dextrose; glycerin; propylene glycol; ribose; triose; tetrose; erythrose; threose; pentose; arabinose; ribulose; xylose; xylulose; lyxose; hexose; allose; altrose; fructose; galactose; glucose; gulose; idose; mannose; sorbose; talose; tagatose; adlose; ketose; heptose; sedoheptulose; monosaccharides; disaccharides; sugar alcohols; xylitol; and polyol.

A contact lens treating solution includes (a) about 0.005 to about 2 wt. %, based on the total weight of the contact lens treating solution, of hyaluronic acid or a salt thereof; (b) about 0.01 to about 1 wt. %, based on the total weight of the contact lens treating solution, of erythritol; (c) one or more nonionic surfactants; (d) sodium chloride, potassium chloride or any combination thereof; and (e) one or more buffers.

The present invention relates to a lens care solution having 0.001 to about 5 weight percent of a low molecular weight amine of the general formula:

##STR00001##

where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or low molecular weight radicals, and R.sub.5 is a low molecular weight radical, or salt thereof; an effective amount of a tonicity agent; and the balance water.
