While everyone who sees halos around lights does not have an eye disease, halos around lights accompanied by other symptoms could signal a serious eye disorder. So, is what you are experiencing just an annoyance or something more disturbing?
It can be especially disconcerting at night if you start seeing halos and bright circles because these vision problems can interfere with your ability to see clearly and make being around bright lights uncomfortable.
What Are the Common Causes of Seeing Halos?
Before we begin discussing some common causes of seeing rainbow-colored halos, you need to understand the basics of how the eyes work. Light entering the eyes bends. When this light bends, it is called refraction.
Sometimes, people see halos around lights when light enters their eyes and bends. If you wear glasses or contacts to correct nearsightedness, you are more likely to see bright rings. This annoying visual sensation and other uncomfortable symptoms may be present.
The following are some of the common causes of seeing halos around lights:
- Dry eye Lasik surgery
- Acute Glaucoma
- Permanent vision loss
- Ocular migraine
- Optic nerve damage
- Severe headache
- Recent cataract surgery
- Fuch’s Dystrophy
- Photokeratitis
- Keratoconus
- Astigmatism
- Corrective eye procedures – Cataracts
Dry Eye Syndrome
Chronically dry eyes can develop changes to the shape of the cornea. If the cornea is shaped incorrectly, focus light scatters when entering the eye instead of bending.
Glaucoma
Glaucoma is an eye condition that results in increased eye pressure. Ongoing increases in pressure can damage the optic nerve. This condition is one of the leading causes of vision loss. In its early stages, you may see bright rings around lights.
Ocular Migraines
An ocular migraine, also known as retinal migraine, can be frightening to experience but is usually short-lived. You may experience rainbow-colored halos, bright flashes, and vision disturbances temporarily. The underlying cause of this condition is not always known.
Cataract Surgery
You will likely see halos around a light source if you have cataracts. Cataracts can change the eye’s surface and make it more difficult to see, even if you wear corrective eyeglasses.
Surgery must be performed to regain vision clarity. The cloudy lens is removed, and an artificial lens is placed. Just after surgery, you may experience light sensitivity or halos surrounding lights.
Fuch’s Dystrophy
This severe eye disorder causes a buildup of fluid in the front of the eye, leading to a swollen and thickened cornea. Over time, this condition degrades your eye health and can lead to you seeing halos or having other severe symptoms.
Photokeratitis
If you have been exposed to UV light sources without protection, a painful eye condition can develop. Exposure to light damages the corneal epithelial cells, leaving the underlying corneal nerves damaged and exposed. Early detection is critical, and this condition can be a medical emergency.
Keratoconus
Keratoconus causes the rounded cornea to become overly thin and develop a bulge that impedes the eye’s lens from transmitting light effectively, resulting in refractive errors and seeing shimmering lights.
Astigmatism
Astigmatism is an abnormal curvature of the cornea or lens of the eye. This condition causes vision distortion, including circles surrounding lights, especially in a dimly lit space.
It is important to note that seeing halo issues can sometimes occur when your eyes are healthy. If the problem persists for a few weeks, there may be serious vision issues or eye disorders that require treatment.
