Hi Bernadette,
Without any other specifics or an exam, it’s difficult make an assessment on Angel. A film on the eye could be a minor issue (a scratch or ulceration) that could resolve with treatment or it could be a more chronic condition (such as dry eye) that will need long term care. The best advice I can give is to not delay getting her looked at by your vet as delaying could cause further problems or make a treatable condition untreatable.
All the best,
Dr. Ryan Llera
