The drops are believed to work by reducing oxidation and glycation damage in the lens, particularly reducing crystallin crosslinking. Randomized controlled trials indicate the drops may be especially appropriate for seniors, or others where surgery is not advised.

“The great question that has never been answered and which I have not get been able to answer, despite my thirty years of research into the feminine soul, is “What does a women want?””
—Sigmund Freud (1856–1939)
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
“To be sure, nothing is more important to the integrity of the universities ... than a rigorously enforced divorce from war- oriented research and all connected enterprises.”
—Hannah Arendt (1906–1975)
