When i wear my contacts and i look at a light, i often see double vision in the light. is this normal?

No: If you truly have a secondary image, this is most often caused by undercorrected astigmatism (ghost image). Sometimes, severe dryness can cause a ghost image but it is usually due to astigmatism. Best to see you ophthalmologist to see what is going on.

No: Contact lens prescription may be incorrect. See if it's there also with glasses. Uncorrected astigmatism is a common cause of blurred edges to an image.
