Thank You For Taking My Question. I've Had A Sudden

Thank you for taking my question. I've had a sudden change in my vision, cloudy in one eye. It happened around noon today and I thought it was my contact lens. Unfortunately when I arrived home and took my lens out, the condition remained. My eyes since this morning have been burning. I do have allergies and astigmatism; however, have never had a condition to my eye sight change so suddenly. The eye is not red nor cloudy or swollen. Thoughts on who to see (primary MD or eye Dr.) and what this might be would be appreciated.
