Putting carboxymethylcellulose sodium in one’s eyes two, three or more times a day may not sound like a great experience. But I can assure you that it can be. Drops of this chemical, called a topical lubricant, help to keep my eyes from burning, avoiding bright lights, becoming red and itchy, and generally feeling miserable.
Like tens of millions of Americans, especially women older than 50, I have dry eye disease, medically known as keratoconjunctivitis sicca. Fortunately, my problem is not severe, certainly not as bad as that of an elderly woman I know who has to use a nightly ointment of mineral oil and Vaseline, which minimizes the dryness but temporarily blurs her vision.
The drops I use, an over-the-counter preservative-free product called Refresh Plus (also sold as generic store brands) that I carry with me at all times, are a crucial measure I take to keep my eyes from becoming overly dry and chronically irritated — but not the only one.
To minimize the drying effect of wind when driving, cycling or sitting in a room cooled by a fan or air-conditioning, I wear wraparound glasses even when I don’t need them to see clearly. Watertight goggles are de rigueur when swimming, even in fresh water. And I refresh my eyes with drops when I watch a movie, work long hours at the computer, or do any activity that depresses the frequency of blinking, which moistens the eyes.
Dry eye is sometimes referred to as “a nuisance complaint — it’s not the sexiest of eye problems,” Dr. Rachel Bishop, chief consulting ophthalmologist at the National Eye Institute, told me. Nonetheless, she said, “Dry eye disease deserves serious professional — and personal — attention. It can be very debilitating and seriously diminish a person’s quality of life.”
