Review: I had one of these for 10 years and the battery corroded in my pen so I had to replace the pen - This is exactly what I was looking for and the price is very fair. We have a small dog sanctuary for bug eyed dogs. Corneal injury is not uncommon. This light allows me to accurately examine their cornea.
Review: Do not buy - This was used less than 10 times and no longer turns on even with a new battery. Seller said since past 45 days no return or replacement. What a waste of money.

### ⭐⭐⭐⭐⭐ I had one of these for 10 years and the battery corroded in my pen so I had to replace the pen
*by M***P on November 3, 2023*

This is exactly what I was looking for and the price is very fair. We have a small dog sanctuary for bug eyed dogs. Corneal injury is not uncommon. This light allows me to accurately examine their cornea.

### ⭐ Do not buy

This was used less than 10 times and no longer turns on even with a new battery. Seller said since past 45 days no return or replacement. What a waste of money.

### ⭐⭐⭐⭐ How to see a contact or piece of one that's lost in one's eye, and check one's cornea for scratches
*by L***E on May 26, 2025*

I had lost a soft contact in my eye. It went off to the side, and I sort of knew where it was, but I couldn't see it so wasn't sure. I kept trying to push it back into the right place, but that would hurt terribly. Eventually, I got it out, but then ... a piece of it was missing! Now there was a tiny piece of plastic floating around in my eye - somewhere. Eventually I got THAT out, by washing my eye over and over. But I realized if I wanted to ever feel OK about wearing contacts again, I'd have to have a less painful way of dealing with an accident like this. So I bought plenty of eyewash, fluorescein strips , and this blue penlight. Fluorescein stains soft contacts, so the contact, or pieces of it, should be visible. It would trash the contact, but that's a lot better than hurting one's eye in the desperation of trying to remove something invisible and lost in it. Also, this penlight and dye may show whether one's corneas are in sufficiently good shape to wear contacts, because damaged places in the cornea show up with the dye and penlight. It's a lot more sensitive than just going by the way one's eye feels. The penlight is awfully expensive for what's just a little flashlight with a blue filter on it, but that's how medical equipment generally is, for some reason. At least it's the right brightness and color.
