When I was younger maybe starting around 10 weeks old, I had terrible tear stains. We tried Angel Eyes due to the reviews but it wasn't working for me!

We had to figure out why I was tearing so much! Well, almost every hour of the day I had hair stuck in my eyes. That cannot be comfortable and it definitely caused me to tear up a ton! I also blame it on allergies and a poor diet!

Mom started removing the hairs from my eyes very carefully with her fingers. She checked my eyes frequently to make sure they're clear of any hairs. Please make sure that your fingers are clean and that your fingernails are short. Sometimes mom will use this antimicrobial eye flush to combat the allergies!

Mom also used this eyewash on my paws when they were itchy! It works wonders!

Every single morning, she would also comb near the underside of my eyes to rid of any eye boogers and crust! (eww I know). This is the comb that we use!

I am only allowed to drink filtered water and not regular tap water!

I am also given probiotics before my meal!

That's our routine for clean eyes! I hope this helps!
