Flashing lights
Blind spots
Blurred or tunnel vision in one eye

2. Optic Neuritis
This is inflammation of the optic nerve, often linked to multiple sclerosis (MS) or autoimmune conditions. It typically causes:
Sudden blurred or lost vision in one eye

Optic neuritis can be an early sign of MS, so any sudden vision issues must be medically assessed right away.

Commonly referred to as a “mini-stroke,” a TIA temporarily cuts off blood flow to part of the brain.
Wa:r:ning signs may include:
Sudden vision changes or loss in one eye
