Dry Eye Syndrome: This condition is characterized by insufficient lubrication of the eyes, leading to irritation, tearing, and pain. The burning sensation on the upper and lower lids is consistent with dry eye syndrome, which is a common condition that can be exacerbated by environmental factors, prolonged screen time, or certain medications.

Allergic Conjunctivitis: An allergic reaction to substances like pollen, dust, or pet dander can cause eye irritation, tearing, and a burning sensation. This condition is often seasonal and may be accompanied by other allergic symptoms.
Blepharitis: Inflammation of the eyelids can cause irritation, burning, and tearing. This condition is often associated with poor eyelid hygiene, meibomian gland dysfunction, or rosacea.
Conjunctivitis (Viral or Bacterial): An infection of the conjunctiva can cause eye irritation, tearing, and pain. The presence of discharge and the nature of the onset can help differentiate between viral and bacterial causes.

Chemical Burn: Exposure to chemicals can cause severe eye irritation, pain, and potentially permanent damage. It is crucial to identify and treat chemical burns promptly to prevent long-term consequences.
Uveitis: Inflammation of the uvea can cause eye pain, irritation, and potentially lead to complications like glaucoma or vision loss if not treated properly.
Corneal Abrasion: A scratch on the cornea can cause severe pain, irritation, and tearing. This condition requires prompt treatment to prevent infection and promote healing.

Sjögren's Syndrome: An autoimmune disorder that can cause dry eye syndrome, among other symptoms. While less common, it is an important consideration in patients with persistent or severe dry eye symptoms.
Trichiasis: A condition where eyelashes grow inward, rubbing against the cornea and causing irritation, pain, and tearing. This condition is relatively rare but can cause significant discomfort and requires proper management to prevent complications.
