@TropicalBabies !
It would be helpful for you to pick them up and inspect them as much as possible - sometimes they have worms and you can't see them, but eventually you will if they do. The issue with eye worms is that if they scratch at their eyes they can get them infected!
I see you are in Kauai, so it is very likely your little ones will get eye worms too (I am in Oahu!) - if you notice those roaches that are the carriers of this worm, your chickens are bound to get eye worms! These bugs hide under anything on the ground, i.e. pieces of wood etc., and if you have trash laying around they'll likely hang out around there.
Now that time has passed, I can say all my chickens have had eye worms multiple times and I've come to accept that I won't be able to prevent it from happening entirely. I treat them maybe 2-3x a year, or as needed, with Ivermectin. I have the injectable liquid, and with a syringe, I first draw in 3 cc/ml of distilled (clean) water into the syringe, and then draw in 1 cc/ml of ivermectin. From this solution, I remove the needle of the syringe, get my partner to hold the chicken, and drip 1-3 drops in each eye for 1-3 days, depending on how many worms I am seeing. For the chicks, I'd say 1-2 drops in each eye, for 2-3 days. It's actually much easier than it sounds! Just make sure they are held well. I believe this de-worms them internally, as well

If you want to eat their eggs one day, I would look into how long you should stay away from eating them. I no longer eat my chickens eggs so I don't even think about it any more!
Good luck and I hope they find some relief!!! Let me know
