Las Vegas sits atop a new list of the 100 hotspots for dry eye, a condition caused when the tear glands fail to keep the eye sufficiently moist. Left untreated, dry eye can boost a person's risk of infection and impaired vision, according to the list's sponsor, the National Women's Health Resource Center (NWHRC).

The non-profit group considered six factors, including temperature, humidity, wind, altitude, pollutants, and eye allergens.

After Las Vegas, rounding out the top 10 U.S. dry eye spots were the Texas cities of Lubbock, El Paso, Midland, and Dallas; followed by Atlanta; Salt Lake City; Phoenix; Amarillo, Texas; and Honolulu.

Dry eye is among the most common complaints brought to eye doctors, accounting for nearly one-fourth of all office visits, the NWHRC said.
