Blurry Vision Causes and Treatment Myopia . Blurry vision in one eye or both eyes may be a symptom of myopia (nearsightedness), along with squinting, eye strain and headaches. Myopia is the most common refractive error and causes objects in the distance to become blurred. Eyeglasses, contact lenses and refractive surgery such as LASIK and PRK are the most common ways to correct nearsightedness. Hyperopia . Blurred vision from hyperopia (farsightedness) is when distant objects can be seen sharply but your eyes cant focus properly on close-up objects or doing so causes unusual eye strain and fatigue. In cases of severe farsightedness, even distant objects may appear blurred. Like myopia, hyperopia can be corrected with eyeglasses, contact lenses or refractive eye surgery.

A type of refractive error, astigmatism usually is caused by an irregularly shaped cornea. With astigmatism, light rays fail to come to a single focus point on the retina to produce clear vision, regardless of how far away the viewed object is from the eye. Astigmatism, like nearsightedness and farsightedness, can be corrected with eyeglasses, contact lenses or refractive surgery. Presbyopia. If youre over 40 and beginning to experience blurry vision up close — when reading a newspaper or other small print, for example — chances are this is due to the onset of presbyopia, a naturally occurring age-related condition. While the symptoms of presbyopia are the same as those caused by hyperopia (blurry near vision; eye strain when reading), presbyopia is a diminished ability to focus on near 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. Presbyopia It affects just about everyone over the age of 45. Most people use reading glasses or special multifocal lenses (bifocal or progressive lenses) for presbyopia, but there also are presbyopia surgery options such as monovision LASIK and conductive keratoplasty for suitable candidates.

At bottom, the view is both blurred and clouded, as it might appear to someone with cataracts. Chronic dry eyes. Dry eye syndrome can affect your eyes in numerous ways, including blurred and fluctuating vision. While artificial tears (lubricating eye drops) can help, more advanced dry eyes may need a prescription medication or punctal plugs to keep the eye lubricated and healthy. Pregnancy. Blurry vision is common during pregnancy and sometimes is accompanied by double vision (diplopia). Hormonal changes can alter the shape and thickness of your cornea, causing your vision to blur. Dry eyes also are common in pregnant women and can cause blurred vision. You should always report any vision disturbances during pregnancy to your doctor. While blurry vision is not always serious, in some cases it could be an indicator of gestational diabetes or high blood pressure. Ocular migraines or migraine headaches. While generally harmless and temporary, blurred vision, flickering light, halos or zigzag patterns are all common symptoms prior to the start of an ocular migraine or migraine headache. Eye floaters. Vision can be blurred by temporary spots or floaters drifting in your field of vision. Floaters typically appear when the eyes gel-like vitreous begins to liquify with age, causing microscopic bits of tissue within the vitreous to float freely inside the eye, casting shadows on the retina. While a normal part of the aging process, if you see a sudden shower of floaters it could signify a torn or detached retina and you should see your eye doctor immediately. Blurry vision after LASIK. Your vision may be blurry or hazy immediately after LASIK or any other type of refractive surgery. Clarity should improve within a couple of days, but it may take several weeks for your vision to stabilize completely. Eye drops and medication. Certain eye drops, especially medicated eye drops containing preservatives, can cause irritation and blurry vision. In most cases, these side effects can be controlled with artificial tears, prescription dry eye medication or punctal plugs. Also, some medications such as allergy pills can cause side effects of dry eyes and blurred vision. During a comprehensive eye exam, your optometrist or ophthalmologist can advise you whether any of your medications might cause blurry vision. Over-wearing contact lenses. Wearing disposable contact lenses (or indeed any type of contacts) for longer than your doctor prescribed will cause a build-up of proteins and other debris on the lenses. This debris can cause blurry vision and increase your risk of eye infections. YOU MAY ALSO LIKE...

Blurry Vision Can Be a Symptom of a More Serious Eye Problem Eye conditions and diseases. If you have sudden blurry vision in one eye and are over 60, you may have developed a macular hole in the part of the retina where fine focusing occurs. Blurry vision also may be a symptom of a detached retina, eye herpes or optic neuritis (inflammation of the optic nerve), among other causes. Certain eye conditions and diseases can cause permanent loss of vision, so its important to visit your eye care practitioner for diagnosis and prompt treatment.

Vision changes such as blurred vision or cloudy vision, as well as glares and night halos, may be symptoms of a cataract. If unremoved, cataracts can eventually grow so cloudy that they obstruct vision to the point of blindness. But by replacing cataracts with artificial lenses, cataract surgery is very successful in restoring lost vision. Glaucoma. Blurry vision or tunnel vision may be indicative of glaucoma. Symptoms can include a gradual or sometimes sudden narrowing of your field of vision accompanied by blurred vision at the edges of your field of view. Without intervention, vision loss will continue, and permanent blindness may result. Age-related macular degeneration. A gradual loss and blurring of vision, including distortions such as straight lines appearing wavy or broken, could be symptoms of age-related macular degeneration (AMD), a leading cause of blindness among older people. Diabetic retinopathy. If you have diabetes, unexplained blurred vision may be due to the onset of diabetic retinopathy, a sight-threatening disease that damages the retina of the eye.

Blurred vision, often in conjunction with double vision, can be a symptom of an underlying health emergency such as a stroke or brain hemorrhage; or it can be an early sign of multiple sclerosis. If you have sudden blurry vision or double vision, see your doctor immediately. If you have some minor blurring that comes and goes, this could mean simply tiredness, over-exposure to sunlight or eye strain. However, sudden or continuing changes in vision such as blurriness, double vision, tunnel vision, blind spots, halos or dimness of vision could be signs of a serious eye disease or other health problem. If you have sudden changes to your vision, you should always contact your eye doctor immediately. thank you
