A relief!
Size: 60 Count (Pack of 1)
I've been using the Blink Better Eye Scrubs daily for about a week now, and they've been fantastic. My eyes tend to be pretty sensitive, but these wipes haven't caused any irritation or discomfort at all, which is a huge plus. Even though "tea tree oil" is mentioned, I didn't notice any scent, which I actually prefer.
The wipes themselves are perfectly moist and feel great on the skin. I really appreciate that one side is softer and the other is a bit firmer, so you can choose what you need. The individual packets are also super easy to open, which makes them really convenient for daily use or when I'm on the go.
They do a terrific job of cleaning my eyelids and lashes, and I've even noticed my eyes watering less since I started using them. I think they offer good value for the quality, and I'd absolutely recommend them, especially if you have sensitive eyes. They're definitely worth buying.

Blink Eye Wipes are the Best
Size: 60 Count (Pack of 1)
My eye doctor recommended a different brand (which I have used) and find these to be just as effective and at a better price. They are very soothing to the eye and a nice treat at the end of the day. They are very soft, with a light & refreshing fragrance.

Good, could be a little better
Size: 60 Count (Pack of 1), Size: 60 Count (Pack of 1)
Thick, generously sized and very durable. With my allergies it's helpful that after thoroughly cleaning around my eye area I can use this to wipe my face and neck, too. I like that each side has a different texture,one for gentle exfoliating, the other for smooth wiping - both sides are soft. There's no real smell to speak of.
The individually wrapped packets also make it very easy to toss these in my backpack, purse, car, luggage.
They could be a little more moist and mintier though. I was hoping for a residual freshness feeling that's only slightly there. Hopefully the company will make some minor tweaks. I'll continue to buy these however, they're a pretty unique product, provide sufficient on-the-spot relief and are a good value.

Covers all my passes
Size: 60 Count (Pack of 1)
I've used several brands of eye wipes and I think I'll stop looking any further after using these.
The wipes are super moist and the largest I've come by.
They are soft thick wipes which I appreciate especially after say cutting grass or any outdoor activities that might attract pollen or dust to my lids. I've used some that are very thin and felt harsh.
My skin feels clean yet moisturized after using them.
I'm totally happy that my lids are not burning and itchy anymore.
