Dry eyes, irritants, and infections can all cause redness of the sclera. Most infections are caused by viruses, but there are bacterial causes as well that require antibiotic treatment. If the redness is caused by irritants (foreign objects rubbing the eye) or dryness, saline eyedrops can help.
Eye-whitening surgery is limited to cases of pterygia and pingueculae, which are benign growths that can cover part of the white of the eye with reddish or yellowish tissue. Surgical removal of these growths will usually leave the affected part of the eye whiter after removal. If the white parts of the eyes are reddish due to dilation of the blood vessels in the transparent membrane that covers the white parts of the eye, constricting the dilated blood vessels with eye drops will help whiten the eyes. Try using over-the-counter eye drops containing naphazoline twice or thrice daily. If necessary, your eye doctor can prescribe eyedrops with a much higher concentration of naphazoline than the over the counter products.
