**Core Concept**
The prolonged wear of contact lenses can lead to eye infections and other complications due to the accumulation of bacteria and other microorganisms on the lens surface. This can result in inflammation of the cornea, conjunctiva, and other ocular tissues.

**Why the Correct Answer is Right**
The symptoms experienced by the patient could be due to contact lens-associated keratitis, a type of corneal inflammation. This can be caused by bacterial, viral, or fungal infections, which can lead to pain, redness, and decreased vision. The prolonged wear of contact lenses can also lead to contact lens-induced papillary conjunctivitis (CLPC), an allergic reaction that causes the conjunctiva to become inflamed and irritated.

**Why Each Wrong Option is Incorrect**
**Option A:** The correct answer is not provided in the question. However, we can still analyze the possible options. Assuming option A is a correct answer, it could be a symptom of conjunctivitis or keratitis, but without more information, it's difficult to determine.
**Option B:** Giant papillary conjunctivitis (GPC) is a type of contact lens-induced papillary conjunctivitis, which can cause symptoms such as itching, burning, and redness. It is a possible symptom of prolonged contact lens wear.
**Option C:** Contact lens-induced uveitis is a rare complication of contact lens wear, which can cause inflammation of the uvea, a layer of tissue in the eye. It is a possible symptom of prolonged contact lens wear.
**Option D:** Corneal neovascularization is a condition where new blood vessels grow into the cornea, which can be caused by chronic inflammation or injury. It is not a direct symptom of contact lens wear.

**Clinical Pearl / High-Yield Fact**
When patients wear contact lenses for extended periods, it's essential to emphasize the importance of proper hygiene, lens cleaning, and replacement schedules to prevent eye infections and other complications.

**Correct Answer:** B.
