It can be because of refractive error or problems of the macula/retina.

Detailed Answer:
Hello
Welcome to Health care Magic.


I am Dr. DADAPEER K, an Ophthalmologist and I answer health problems related to eye.

I reviewed your history.

These symptoms of blurring of vision in one eye indicate a most probable refractive error in that eye.
This can be detected by simple vision and refraction testing done by optometrist. If vision and refraction testing is normal then we need to rule out other causes involving the retina like serous retinopathy or macular problems of the retina. These problems can be detected by ophthalmoscopy by a eye specialist.
Hence I advice you to consult your optometrist or ophthalmologist for examination and vision testing to find out the underlying cause.


Hope this answers your question.


Thank you

Brief Answer:
It can occur in migraine.

Detailed Answer:
Hello
Thank you for the follow up question.

Migraine can cause this but in migraine the blurred vision will be transient, seen before an episode of migraine and recovers completely after the episode.
If the blurred vision is transient and being followed by headache then it confirms migraine.

Hope this answers your question.

Thank you
