If the lines appear so wavy and you see a dark spot in the middle, the cause might then be macular degeneration, and you should see an ophthalmologist at once.

Age-related macular degeneration (AMD) is an eye disease which shows up as a dark blurry black spot, in the center of vision, usually in one eye only. Over a period of time, the progressive disease then destroys central vision which is required for reading and other close work including driving and seeing distances.

AMD not affect side vision. The condition is the leading cause of vision loss in people who are over the age of 60.

Eye floaters are small specks that float into your field of vision. While they might also be a nuisance, eye floaters are not to cause you any discomfort.

Eye floaters appear as gray dots, lines or blobs. Occasionally, a large floater might cast a shadow over your vision leading to a dark spot in your sight. Due to the fact that the floaters are inside the fluid of your eye, they move as your eyes move.

Eye floaters appear when you stare at a bright, like the sky, a reflective object, or even blank paper. Eye floaters are present in only one eye, or they might also be in both.

What causes eye floaters?

Age-related changes to an eye are the common cause of the condition. The cornea and lens that is at the front of the eye focus light onto retina which is at the back of your eye. As light passes from the front of an eye to back, it passes through the vitreous humor, which is a jelly-like substance that is inside your eyeball.

Changes to vitreous humor might lead to eye floaters. This is a common part of aging and is called the vitreous syneresis. The thick vitreous starts to liquefy with age and the inside of eyeball becomes crowded with a lot of debris and deposits. The microscopic fibers that is inside the vitreous clump together. The debris can be caught in the path of light as it passes through your eye. This casts shadows on your retina, leading to dark spot in eye.

Less common causes of the condition include:

  • eye injury: if your eye is damaged during an accident, you might then experience the condition
  • Nearsightedness:  nearsighted people experience the condition frequently. Vitreous syneresis also happens at a faster pace in people who experience nearsighted vision
  • inflammation: swelling and inflammation in eye, often brought about by infection, can lead to eye floaters
  • deposits: crystal-like deposits form in vitreous and interfere with light that is passing from front of eye to back
  • Diabetic retinopathy: diabetes might damage the blood vessels. When the vessels are damaged, the retina might not interpret the images and light that is hitting it
  • intraocular tumors
  • visual aura of a migraine headache

Eye floaters are common after age of 50. By age of 70, most people will have experienced the condition at least once in their lives. Babies are usually born with clear vitreous, so it is very rare for children who are under the age of 16 to have the condition.

Sudden Black Spots in Vision

Eye floaters are the small spots, flecks that drift aimlessly around in your vision. While annoying, ordinary spots are common and aren’t cause for alarm.

Floaters typically appear when the small pieces of the eye’s gel-like vitreous break loose within inner back portion of your eye.

In children, the vitreous contains a gel-like consistency. But as we get older, the vitreous starts to dissolve and liquefy so as to create a watery center.

Some undissolved gel particles might sometimes float around in liquid center of the vitreous. The particles might take on several shapes and sizes becoming eye floaters.

You’ll notice that the dark spot in eye as well as the eye floaters are more pronounced if you gaze at a clear or a computer screen with a light-colored background. You won’t see small bits of debris that are floating loose within your eye.

Instead, shadows from the floaters are cast on the retina as light passes through your eye, and the tiny shadows are what you see.

Dark Spot in Eye Not Floaters

Seeing occasional dark spot in eye is very much normal. Most of the people experience them in their lives. Sometimes, it is an indication of a potentially dangerous condition.

When you see a flurry of the black spots, it might indicate that your retina is detaching slowly from the back of your eye. If you see a lot of such black spots, you must ensure that you seek medical care immediately.

There are many causes for pigmentation changes in whites of eyes of small children. But, by far the most common is a mole, which are collections of pigmented cells known as melanocytes in lining which covers the eye.

These collections of pigmented cells happens anywhere on surface of the body, which includes the eye. Generally, these are benign, but there is a small chance they might transform into melanoma, which is a serious form of cancer.

Thus, they should be checked out by your doctor. Other common causes of pigmentation changes in eyes of young children include small bruises, which are due to minor trauma to eyes and rupture of the small blood vessels in active children.

If you have several of them that they block your vision, then your eye doctor might suggest surgery known as vitrectomy. He’ll get rid of the vitreous and replace it using a salt solution.

You might have complications such as:

  • Detached retina
  • Torn retina

The risk is low, but if these problems do occur, they might permanently damage your vision.

The visible surface of eyeball consists of cornea (the clear front window of eye), the pupil, the iris, the sclera and the conjunctiva (a highly vascularized covering of the sclera).

The following are various medical conditions which are said to be possible causes of dark spot in eye.

Axenfeld nerve loop: Long posterior ciliary nerve loops which are found within sclera. Loops might appear as white nodules that are under the conjunctiva and are surrounded by a pigment.

This loops are common and might be confused as an embedded foreign body in an eye.

Crystal deposits: The use of vitamin C eye drops can lead to crystal deposits to form in cornea of your eye.

Horner-Trantas dots: This are characterized by small rounded papilla, which is found on the surface of the eye. Additional symptoms include severe itching, foreign body sensation, mucous discharge, abnormal contraction of the eyelid, and also blurring of vision.

This condition affects young males in hot dry climates in a seasonal manner and is said to be an allergic and also inflammatory response.

Nevus: Occasionally known as a “freckle of the eye,” similar to a mole that is found on skin. A nevus is a colored growth that is found in front of eye, around the iris, or even under the retina which is at the back of the eye. They are harmless, but can develop into cancer of eye.

Dark Spot on Eye Iris

Freckles, small accumulations of the melanin or even the pigment, appear anywhere on skin and sometimes in an eye, accounting for majority of eye spots. In most of the cases, a dark spot in eye can be seen by an ophthalmologist.

This is true if the freckle happens inside the colored portion of the eye. When the freckle appears on the sclera, it shows up as a brown spot.

Appearance of Dark Spots in Eye

Eye freckles, also known as choroidal nevus, vary according to the size and color. Most of the people never know that they have one unless their ophthalmologist tells them so.

But, they can get large enough to becoming easily visible to naked eye. The color ranges from a light gray to black.


The eye possesses a membrane which is full of pigment cells known as the choroid. The pigment cells clump together abnormally, leading to an eye freckle. Rarely, eye freckles are seen at birth. Usually, developing at similar time as skin freckles.


Because dark spot in eye rarely lead to trouble, they do not require any treatment, according to doctors. When spots are very troublesome, they are treated through laser surgery or radiation therapy.


Your ophthalmologist might choose to inspect or even run some tests on new choroid nevus.

During the examination, your doctor might look closely at the spot and at the blood vessels that are surrounding the spot with a special procedure known as a fluorescein angiogram. This particular procedure allows the doctor to take pictures of freckle from the back of your eye.
