ROHTO New Rohto Dry Aid EX Eye Drop – 10ｍl – has 60 times more high viscosity than other Rohto products. Contains high molecular HEC and extremely high viscosity (only Rohto has this technology), which keeps liquid staying on eye's surface. Not only provides moist but keeps eyes moist for a long time. Thick liquid stays on and keeps your eyes moist and protected. Ranked No.5 selling eye drop at Yahoo! Shopping Japan in 2017. Apply 1 – 2 drops per use: up to twice a day. Its unique micro-emulsion formula delivers relief in a clear and non-blurring drop, so you can get right back to the things you love. No need to wait for the blur to go away, a common problem with other lubricant eye drops.
