Blurred vision in only one eye may suggest disorders that occur in the brain or central nervous system, including migraine headaches or pressure on the optic nerve from a tumor. Eye trauma is another cause that might affect only one eye, either from the injury itself or from delayed effects such as cataract formation.
Blurry vision is very common. A problem with any of the components of your eye, such as the cornea, retina, or optic nerve, can cause sudden blurred vision. Slowly progressive blurred vision is usually caused by long-term medical conditions. Sudden blurring is most often caused by a single event.
Although much less common, it is possible to have one nearsighted and one farsighted eye - this is a unique subset of anisometropia called antimetropia. Anisometropia is actually fairly common. An estimated 20% of people have an inter-ocular difference of 0.5D or greater, and 2-3% have a difference of 3D or more.
Remedies for Naturally Enhancing Vision

Eye dominance can vary from person to person. One person may have strong degree of dominance in one eye, while another person may have an eye with a lesser difference in dominance from the other eye.
A person with total blindness won't be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy.
Blepharoplasty. Blepharoplasty is a type of cosmetic surgery that corrects uneven eyelids. It is a frequently performed aesthetic procedure. During the procedure, a surgeon will remove excess fat, muscle, or skin from around the eye area to make the eyes appear more symmetrical.
Anisometropia is a condition where the refraction of a person's eyes varies by more than 1 diopters (D). It often manifests in few symptoms, but at its most severe, anisometropia can cause visual blurring, alternating vision, double vision, and a frequent need to squint. It can even cause amblyopia.
One eye may have moderate or advanced glaucomatous damage, while the other eye has very little or none. This variation in the extent of the damage can cause confusion, and the mistaken perception that only one eye is involved.
Among the many methods available to correct anisometropia are correction with spectacles or contact lenses. When spectacles are used, the difference in image formed by either eye prevents perfect fusion of two images, causing loss of binocular vision and usually amblyopia in the affected eye.
Nearsightedness, color blindness, and lazy eye (amblyopia) are often inherited, says Stuart Dankner, M.D., a pediatric ophthalmologist in Baltimore, Maryland. If both parents are nearsighted, a child has a 25 to 50 percent chance.
But if one eye is blurry or you have blurry vision, that can be a sign of health problems as well. And often a treatment of this conditions will clear up your vision. Sudden blurry vision isn't normal, so if it ever happens, be sure to call your doctor right away.
Tears lubricate, nourish, and protect your eyes, and you're constantly producing tears even while asleep. Sometimes, however, your nightly tears can dry on the surface of your eyes, causing blurry, hazy vision in the morning. Blinking a few times after waking up can remoisten your cornea and get rid of blurriness.
Eye exercises:It is better to opt for eye exercises before the blur gets worse or leads to serious illness. Simple eye exercises can help you maintain optimal vision. Warm your eyes regularly by rubbing your hands together and then placing them over your eyes for 5-10 seconds. Repeat this three times for each session.
One of the key signs that you're having a stroke is a sudden, painless change in eyesight. You might have blurry or double vision. Call 911 right away if you have either of these changes and other stroke warning signs, such as: Dizziness.
Treatment OptionsThe treatment of blurry vision depends entirely on what is causing the blurring. Refractive errors like hyperopia, myopia and astigmatism can be corrected by using eyeglasses or contact lenses, the latter being a more comfortable option, but it's important to keep your contacts clean.
An eye stroke, or anterior ischemic optic neuropathy, is a dangerous and potentially debilitating condition that occurs from a lack of sufficient blood flow to the tissues located in the front part of the optic nerve.
In the long term, when extreme stress and anxiety happens frequently, your body's heightened cortisol levels can cause glaucoma and optic neuropathy, which can lead to blindness3. Our bodies are complicated, which can make it difficult to find the cause of a symptom, including sudden blurred vision.
20/30 to 20/60, this is considered mild vision loss, or near-normal vision. 20/70 to 20/160, this is considered moderate visual impairment, or moderate low vision. 20/200 or worse, this is considered severe visual impairment, or severe low vision.
