I disagree respectfully, since it appears to be bubbles in the eyes. It might a respiratory disease such as MG, or possibly coryza if there is a bad odor and thick nasal secretions. How is the ventilation in your coop, and do you smell any ammonia in there from droppings? Are you noticing any sneeze or cough, crackles or wheezes during breathing? Can you try and clean the eyes with a commercial eye was or saline? Get some Terramycin eye ointment from the feed store, or if unable, use plain Neosporin or Triple Antibiotic Ointment from a clean tube in the eye twice a day.
If you are dealing with a respiratory sinus infection, you may need to use an antibiotic such as oxytetracycline or Tylan. That is about all feed stores carry. If they smell bad and it could be coryza, you can try a sulfa antibiotic from a vet or get one online. Testing is the only way to know what you are seeing. Ammonia odor in the coop can burn eyes causing ulcers and swelling, and eventual blindness.
