Waking up and finding that you have perfect vision in one eye but in the other your vision is blurred out may be a cause for worry. At times what we may see as One Eye Blurry is due to a simple refractive error or dryness. Also at times this may be a sign of an eye issue which requires medical care. What is most important is to not ignore a change in your vision which is new or unexplained.
Blurry Vision in One Eye may present slowly over time or all of a sudden. What causes it may be the cornea, lens, retina, optic nerve or another element of the visual system.

Issues with the eye’s length, corneal shape, or the aging lens may cause these. If you are seeing blurred vision in one eye that doesn’t improve with blinking or rest, an eye exam is recommended to determine the cause.
