Sudden Loss of Vision: This refers to either a complete or partial loss of vision in one or both eyes. This could be from, but not limited to, retinal detachment, macular degeneration, and diabetic retinopathy.
Flashes of Light: These generally resemble lightning bolt flashes in the side of your vision and can happen spontaneously or after trauma. This can be the start of a retinal detachment and time is of the essence.
Floating Spots: Floaters are often described as cobwebs or bugs racing across the eye. These spots move as the eye moves. A few seen now and again are common and are due to normal degeneration of the vitreous. However, if several are seen suddenly, especially in one eye, that vitreous – or worse, the retina – may be detaching.
Double Vision: Sudden onset of double vision is an urgent symptom which needs to be evaluated immediately by an optometrist. The best thing to do if this is noticed is to see if it occurs binocularly (both eyes open) or monocularly (one eye open). Binocular double vision indicates a muscle issue which is typically related to diabetes or trauma. Monocular double vision indicates either complications of systemic disease or cataracts.
Pain: Sharp eye pain can be related to a variety of ocular problems and should be seen by an optometrist promptly.
