Since you wear contact lenses and were using Clearine for redness, the safest and most suitable substitute is a lubricating (artificial tears) eye drop rather than strong ?redness remover? drops, because lubricants are gentle, reduce irritation, and are safer for regular use with lenses These drops contain lubricants like carboxymethylcellulose, which act like natural tears and relieve burning, redness, and discomfort caused by dryness or lens use. If irritation is severe, and if redness or blurred vision continues, consult an eye doctor.
