In order to make a observation of diagnosis, I would have to have a much closer look at Layla's eyes under a light. What I can observe is swelling of the eyelids, both upper and lower on both sides. An allergic reaction can certainly cause that to occur. Conjunctivitis might be a follow up to the allergic reaction due to rubbing of the eyes. If this is an allergic reaction, benadryl can sometimes get matters under control. Other times, a steroid is required to reduce the body's inflammation both locally and systemically. You can take a wait and see approach if you'd like, but if those eyes swelled up suddenly I would be more inclined to have her seen right away. Hope this makes sense
