Rohto® was founded in Osaka, Japan in 1899 and is one of the world's largest manufacturers of eye drops.

ROHTO® Cooling Eye Drops not only relieve redness, dryness and irritation, but also provide a special cooling sensation that helps "wake up" tired eyes.

Athletes can benefit from ROHTO® Cooling Eye Drops because many often experience dry, irritated eyes as a result of constantly battling environmental or chemical elements, such as wind, sun, water and dust, during their training and competitions. They can also provide post-workout relief; just as you "cool down" your body after a tough workout, you can also cool down your eyes.

Rohto® Cooling Eye Drops are popular among endurance athletes like the men and women who participate in Ironman and Iron Girl competitions because of their ability to soothe and cool irritated eyes so athletes can focus on the finish line, not the irritation.

The newest product offering, ROHTO® Hydra is specifically formulated to lubricate and provide long-lasting moisture for dry, irritated eyes with the closest hydration to natural tears, while also providing the brand's signature cooling "kick." Rohto® Cool is a general purpose eye drop that combines redness relief with a gentle cooling sensation. Rohto® Ice is used to relieve redness while also soothing itch, irritation and burn with an intense cooling sensation. Rohto® Arctic revives strained, overworked eyes and relieves redness with a more intense "pick me up" sensation.

The recommended usage is one or two drops in each eye up to four times daily. If you're wearing contact lenses, remove contacts before using ROHTO, and wait at least 15 minutes before re-inserting.

Rohto® Cooling Eye Drops retail between $6.99-$8.99 at drugstores like CVS, Walgreens, Rite Aid, Walmart, Safeway and drugstore.com.
