Tears help lubricate and protect the eyes from irritation (such as dirt and dust) and infections. When you blink, a layer of tears—called tear film—covers the eyes' surface. The tear film has these ...

A panelist discusses how a prospective study demonstrated that twice-daily use of a nasal spray significantly improved tear ...

Top Cleveland Clinic and University of Iowa eye doctors explain it's not just blurry vision or irritation—and not just any ...

All participants had their corneal curvature measured using the tests in the same order as each other and the tests were taken within 10 mins of each other to reduce fluctuations in tear film.

When conducting IOL power calculation, tear film instability significantly influences various measurements of corneal refractive power and astigmatism, making errors in the calculation more likely ...

This physical disruption makes the tear film less stable and more prone to breaking during normal blinking. The resulting increase in friction creates a cascade of problems.

The lubricant significantly increased the mean tear film break-up time from 3.32 seconds at screening and baseline to 7.74 seconds on day 28 of treatment (P < .0001).
