What causes uneven vision?

A refractive error is when the light is not correctly focused as it travels through the lens of the eye. Refractive errors occur due to nearsightedness, farsightedness, or astigmatism, in which the surface of the cornea or lens is uneven, causing blurred vision.

What causes dark shadows in corner of eyes?

As you age, the vitreous — a jelly-like material inside your eyes — becomes more liquid. When this happens, microscopic collagen fibers within the vitreous tend to clump together. These bits of debris cast tiny shadows onto your retina, and you perceive these shadows as eye floaters.

What is dimness vision?

Amblyopia is a dimness of vision, especially when occurring in one eye without apparent physical defect or disease.

What causes ghost images in vision?

When one eye sees a second image (often a ghost image) while the other eye is covered, this is known as monocular diplopia. It is most commonly caused by astigmatism (a defect in the curvature of the cornea or shape of the lens) or early formation of cataracts (clouding of the eye lens).

Why do the inside corners of my eyes look bruised?

Allergic shiners, also called allergic facies or periorbital venous congestion, are a symptom of allergies. They appear as dark circles under the eyes and resemble bruises or “black eyes.” Allergic shiners are caused by the pooling of blood under the eyes, due to the swelling of the tissue in the nasal cavities.

What does it mean when you lose vision in one eye temporarily?

When a blood vessel in your retina tightens, it causes a vasospasm. This cuts down on blood flow, which can bring on temporary vision loss in one eye. Various conditions can lead to a vasospasm. These include a retinal migraine, atherosclerosis, and high blood pressure.

What is darkened vision?

Darkening (ophthalmology), vision loss or weakness that occurs without an apparent lesion affecting the eye.

Can you get astigmatism in one eye?

Astigmatism almost always occurs in both eyes. The condition can occur in only one eye but usually is the result of a physical injury.

What is astigmatism how it can be removed?

Spherical lens power is used to correct near sightedness or far sightedness, whereas astigmatism requires an additional “cylinder” lens power, to correct the difference between the powers of the two principal meridians of the eye. So, Astigmatism for a human eye can be removed by using cylindrical lens.

Can you experience sudden blindness in one eye?

You can experience sudden blindness in both eyes or just in one eye. The loss of vision can be complete or only partial. You can also experience a blurring of vision that comes on suddenly.

What causes painless blurry vision in one eye?

Painless blurry vision in one eye can be caused by ischemia or decreased blood flow to structures of the eye. This occurs more frequently in patients with atherosclerotic disease, including coronary artery disease or peripheral vascular disease. Other causes of sudden vision loss include infection, inflammation, vasculitis, and trauma.

Can presbyopia cause blurred vision in one eye?

Typically, presbyopia causes blurred vision up close in both eyes, but may be more pronounced in one eye if you have different refractive errors in each eye.
