Blurry Vision

Blurry vision is a decline in sharpness in eyesight, making vision appear hazy and out of focus. Blurred vision is the most common reason for eye examination requests. Blurring may happen occasionally, or objects may be seen as blurred all the time. Blurred vision makes it especially difficult to sustain up-close work for long periods of time. When blurred vision in one eye or both eyes occur, it is time to see an eye care provider. Having trouble focusing eyes together can be a visual expression of a variety binocular vision dysfunctions . Treatment for blurred vision is based on the cause or diagnosis.

Causes of Blurry Vision

Short Sightedness

Myopia or nearsightedness can cause blurry vision. You may have blurry vision in one eye or both eyes and won’t be able to see far away objects clearly. Use of contact lens or eyeglasses can help correct myopia. Refractive surgery can be a permanent solution.

Long-Sightedness

Also called Hyperopia, when a person is long-sighted, or far-sighted, objects that are close appear blurry as the eye cannot focus properly. If the same object is moved further away, clarity is regained. Hyperopia can be treated with corrective lenses or LASIK eye surgery.

Astigmatism

Astigmatism can cause blurry vision at any distance. Astigmatism refers to an irregularly shaped cornea which doesn’t allow the light rays to come to a single focus point on the retina to produce clear vision, regardless of how far away the object is from the eye.

Cataracts

Vision changes like cloudy vision or a blurry spot in vision, night halos or glares at night, can indicate a cataract. If they are not removed, cataracts can grow cloudy and can obstruct vision to the point of blindness. You can decide to have cataract surgery to replace cataracts with artificial lenses. This is proven way to restore lost vision.

Presbyopia

Presbyopia is a naturally occurring age-related condition that manifests as blurry vision of objects that are close-by. It usually affects people above the age of forty. It occurs due to the lessened ability of the eye to focus on close objects due to hardening of the lens inside the eye rather than a defect of vision caused by the overall shape of the eye like hyperopia.

Dry Eye

Dry eye syndrome, whether intermittent or chronic, can affect your eyes in numerous ways. It can cause blurred and fluctuating vision. Many people relieve dry eye syndrome is by using artificial tears like lubricating eye drops. More advanced cases might need a prescription medication or punctal plugs to keep the eye lubricated.

Floaters

With eye floaters, vision can be blurred by temporary spots or floaters that drift in your field of vision. Blurry vision and floaters usually appear when the eye’s gel-like membrane starts to liquify with age, which causes microscopic bits of tissue within the membrane to float freely inside the eye and cast shadows on the retina. Though it is usually a normal part of the aging process, a sudden shower of floaters as it could signify a torn or detached retina, necessitating an emergency doctor visit.

Glaucoma

Glaucoma belongs to a group of related eye disorders that damages the optic nerve resulting in loss of vision. Glaucoma can be a direct cause of blurred vision. Symptoms of glaucoma are not visible until it has a significant effect on one's eyesight. The best way to catch glaucoma is to undergo an eye examination periodically. If you are diagnosed, your treatment options include medication, laser or glaucoma surgery depending on the severity of your condition.

Diabetes

Diabetes is the most common cause of blurry vision. Studies have shown a positive correlation between diabetes and cataracts due to elevated sugar levels in the body. If you are experiencing blurry vision due to diabetes, be sure to see an eye doctor right away, as you can be at risk of other eye problems.

Pregnancy

Pregnant people may experience morning sickness, swollen feet, constipation, back ache, and fatigue but the hormonal fluctuations in the body can also lead to blurry vision. Vision may return to its normal state following an end of pregnancy, but a doctor should be consulted if symptoms persist.

Contact Lenses

if contact lenses are worn for a longer period than prescribed, proteins and other debris from the tear ducts will start building up on the lenses. This will increase the risk of eye infections and can cause blurry vision.

Migraines

A migraine is not just a painful headache. There are many other symptoms, including blurry vision and sensitivity to light. These signs may appear even before a migraine starts, and they may last until it's over.

Macular Degeneration

A gradual loss and blurring of vision could be symptoms of age-related macular degeneration (AMD), a main cause of blindness, especially among elderly people.

Psoriasis

Psoriasis sufferers may experience itchy or sore patches of skin, Joint pain and inflammation or Thick, red, scaly patches on the skin. Psoriasis can affect eyes as well. It can cause a condition called uveitis, when inflammation causes swelling leads to blurred vision, among other symptoms.

MS

Blurry vision can be one of the earliest symptoms of multiple sclerosis (MS). Inflammation along the nerve that connects your eyes to your brain, the optic nerve, can be a result. Optic neuritis can result from problems with the optic nerve, which can give you blurry sight, loss of color and pain when you move your eyes. It often happens in just one eye.

Brain Tumor

A tumor in your brain can make pressure build inside your skull. That can cause many symptoms, including blurred vision.

Parkinson's

Parkinson's may change how your eyes move. As your sight seems less sharp, you may strain your eyes because they have to work harder to focus. This can cause blurry vision.

Treatment Options

As you can see, many different issues can cause blurry vision, and it can often be a symptom of another underlying illness. Chronic blurry vision is usually a red flag that something else is wrong, so remember to see a doctor ASAP if you experience it! Depending on the cause, treatments can include minimally invasive options like eye drops, to more serious interventions like surgery.
