Blurred Vision Causes

Blurred vision is a common eye problem that results from visual disturbances. Blurred vision is generally described as the inability to clearly see or outline details and/or loss of sharpness of vision. One may experience blurred vision in one eye or blurred vision in both eyes. Other visual problems that can be possible causes of blurred vision include blind spots, halos, floaters, etc. Blurred vision causes are not always easy to diagnose, hence it becomes very important to have your eyes evaluated by an ophthalmologist.

Causes of Blurred Vision

Optometrists evaluate the eyes to diagnose eye problems and treat them accordingly. Vision changes and problems like blurred vision can be caused by many different conditions, some of them have been listed below.

Cataracts: Cataract is the formation of a cloud over the lens of the eyes. This cloud is usually clear and lets light pass through easily, enabling us to have a clear vision. When the cataract does not let light pass through easily, it causes blurred vision.

Age-Related Muscular Degeneration: Age-Related Muscular Degeneration (AMD) is a common eye disease associated with aging. AMD is responsible for destroying central vision, which is needed for seeing objects very clearly. This eye disease can either inflict a person very slowly or very fast.

Glaucoma: Glaucoma is found mostly in people suffering from diabetes and diabetic retinopathy. Here, there is gradual deterioration of the peripheral vision. There are four types of glaucoma; Open-angle glaucoma, angle-closure glaucoma, congenital glaucoma and secondary glaucoma. This eye disorder results in optic nerve damage.

Floaters: One of the temporary blurred vision causes is floaters. Sometimes we notice floating specks in front of the eyes, but feel that it is not on the surface, but inside them. Floaters are basically cellular debris that disappear without treatment. Consult a doctor if there is an increase in them.

Migraines: A migraine is a severe headache characterized by pain in the head, scalp, or neck. Feeling of nausea and blurred vision is common when the migraine attack is severe. Some people suffer from an ophthalmic migraine, where one only experiences visual disturbance without a headache. A migraine attack is one of the occasional blurred vision causes.

Optic Neuritis: The cause for this optic neuritis is inflammation of the optic nerve is unknown. However, this optic disorder is one of the sudden blurred vision causes, as its symptoms include sudden, reduced vision in the affected eye. Restoration of vision and vision correction maybe difficult in such cases.

Brain Problems: Optic nerves directly connect the sensory vision to the brain. Any upsetting of these nerves can cause blurred vision. Some common intermittent blurred vision causes include stroke, optic or brain tumors, trauma to the eyes, bleeding into the eye, increased pressure on them, and a few specific cardiovascular diseases etc.

Refractive Eye Conditions: Occasional blurred vision causes include refractive eye conditions; myopia (nearsightedness), hyperopia (farsightedness), presbyopia (the cornea and lens of the eye become less stretchable), and astigmatism (distorted shape of the cornea or the lens) to name a few.

There are many blurred vision causes like scratched cornea, or dry eyes, etc. that go away with a little rest, some medication and meticulous eye care. However, visual changes must never be ignored, especially if they start to disrupt our daily routine, as they may be a vital indicator of an underlying disease.
