You may have experienced this sensation if you have ever been hit in the eye and see "stars." These flashes of light can appear off and on for several weeks or months.

Why do I see waves of light in my vision?

Most flashes happen when the vitreous gel inside the eye shrinks or changes, pulling on the retina (the light sensitive lining of the eye). Flashes of light can also happen if you're hit in the eye or rub your eyes too hard. In both cases, the flashes are caused by physical force on the retina.

What does it mean when you see waves?

Wavy lights in the periphery of your vision can arise for a multitude of reasons.

You should be evaluated by an ophthalmologist as soon as possible.

This leakage can impact vision, causing blurred vision and other eyesight changes, like wavy or double vision.

What causes floaters? Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of your vitreous (the gel-like fluid that fills your eye) stick together and cast shadows on your retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floaters.

What causes visible waves?

Air at different temperatures has different indices of refraction. So the varying density/temperatures cause a lens effect - thus the waviness.

What does it mean when you see ripples?

Most often, kaleidoscope vision is a symptom of an ocular migraine or a migraine with aura. But it can also be associated with other conditions, including multiple sclerosis (MS), stroke, and diabetes.

What is a shimmering wave in your vision?

What are the symptoms of retinal detachment?
  • A lot of new floaters (small dark spots or squiggly lines that float across your vision)
  • Flashes of light in one eye or both eyes.
  • A dark shadow or “curtain” on the sides or in the middle of your field of vision.

Is wavy vision an emergency?

Why is my vision pulsing?

Why do I suddenly see squiggly lines in my vision?

Most eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes liquifies and contracts. Scattered clumps of collagen fibers form within the vitreous and can cast tiny shadows on your retina. The shadows you see are called floaters.

Why do I see random flashes of light?

Eye flashes are generally caused by the vitreous fluid in the eye pulling away from the retina. Random flashes of light in the field of vision are commonly caused by ageing, as the older a person gets, the more liquid the vitreous gel becomes leading to its separation from the retina.

What are heat waves shimmering in peripheral vision?

If you are experiencing flickering, flashes or shimmering “heat waves” in your vision, it is important to have your eyes checked. While ocular migraines are not serious, it is necessary to rule out any sight-threatening conditions such as a detached retina, which requires immediate attention.
