Hello,
With the question “What is double vision? ”, the doctor would like to answer as follows:
Signs of double vision may indicate damage to the brain and visual pathways. Seeing many small spots is cloudy, seeing bright streaks especially at night is often due to detachment of the posterior vitreous membrane.
Therefore, you need to see a doctor immediately and may need a cranial MRI for specific examination.
If you still have questions about eyes with double vision, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
