My lower left eyelid has pulled away from my eyeball and I would like to know if this is normal? (photos)

This can happen due to swelling from the surgery.  It should improve gradually.  I would recommend upward massage on your lower lid upward from your cheek up to the lower lid margin to counteract any scarring that may be pulling the lid down. 

You have lower eyelid ectropion after blepharoplasty. It is still early in the healing process. Recommend doing squinting exercises. Discuss with your surgeon and/or see an oculoplastic specialist.
