I'm a 18 year old girl and my left eye is fuzzy/blurry today, even with my contacts n?

See opthalmologist . You may have a mild condition known as "floaters" where eye debris in the vitreous humor of the eye moves and obscures your vision periodically. However, you need to see an opthalmologist to rule out a significant condition known as retinal detachment that can permanently cause vision loss. You could have allergy symptoms that could temporarily cause blurry vision but would occur in both eyes.
