Lately I've been having bright colors and blurred vision in my left eye. It starts in the corner and works it way a cross the bottom. It blurs my vision on the side and on the bottom.
It last for about 15 to 20 minutes and after it's gone away I have a headache.
Thanks for your Question
What you have is called migraine with aura followed by headache. Arura is visual and sensory disturbances that occur before headache such as flashes of light, blurred vision, vision lost, Shimmering stars, blind spots and Zigzag lines.
Aura usually last less than 60 minutes followed by headache. You should visit a neurologist for full examination and to give you medications that prevent these attacks.
