Unlike eye drops which can be difficult to get in your eye - I normally get the drops down my face instead - this is a spray which you use with your eyes closed, so it's pretty much foolproof. You just have to make sure the nozzle is facing the right way before you close your eyes and spray!
I didn't really understand how this was going to work considering you use it on closed eyes, but it really makes a difference. I tend to spray it on both closed eyes at once and then keep my eyes closed for a few seconds while the cooling sensation penetrates my eyes and makes them feel comfortable and refreshed. The spray mist works by repairing and replenishing the natural moisture barrier in your eyes.
This is going to be staying in my handbag for any time when my eyes are feeling itchy or dry as it instantly sorts them out, and for times when I have to work late and my eyes feel tired and sore from staring at my PC all day. It doesn't mess up or smudge eye makeup either, which is a bonus for me.
