![]() ![]() Cataracts are most often seen in older adults, though they progress slowly over time and usually begin to develop around age 50. Seeing halos around lights is one of the most common symptoms of cataracts.Ī cataract develops when the eye’s naturally transparent lens becomes cloudy or opaque. This can cause the light that enters the eye to bend in an unusual way and result in the appearance of halos. AstigmatismĪstigmatism occurs when the cornea is irregularly shaped. When this occurs, it can alter the shape of the cornea and cause light entering the eye to scatter- resulting in the appearance of halos around lights. Dry eye syndromeĭry eye syndrome (DES) occurs when the eyes are chronically dry. If you see haloes, contact an eye doctor near you, who can diagnose and treat any underlying vision condition.Įye conditions that affect corneal shape 1. Since the cornea is responsible for bending light as it enters the eye, if you are seeing halos around lights, you may have an eye condition that is affecting the shape of your cornea. If any of these components do not function properly, or are irregularly shaped, vision problems can occur. The process of seeing is dependent on the perfection of the eye and all of its structures, including: The lens adjusts its shape to bend and focus the light a second time, to ensure that a clear image will be seen.Īfter it bends a second time, the light travels to the back of the eye which is filled with a clear, gelatinous substance (vitreous) until it reaches the retina, the light-sensitive layer at the back of the eye.įrom the retina, the visual information is sent to the brain where it is interpreted and processed for the production of a clear image. The light then passes through the pupil to the lens behind it. The cornea bends the light before it passes through a watery substance that fills the area behind the cornea (aqueous humor), on its way to the pupil. When we look at an object, the light that is reflected off of the object enters the eye through the clear front layer of the eye, called the cornea. ![]() In order to produce a clear image, the eyes must complete a specific process that heavily relies on the integrity of each of the ocular structures. The appearance of halos around light sources can be caused by a variety of eye conditions, specifically those that alter the shape of the cornea and cause the light that enters the eye to bend in an unusual way. ![]() They are most often noticed at night time around street lights and headlights and can significantly affect vision clarity while driving. Halos are bright, colorful circles that appear around lights. If you notice a sudden appearance of halos or they’re accompanied by pain, blurred vision or other severe symptoms, seek immediate medical care, as this can signal a serious eye condition. Seeing halos around lights can be a cause for concern, or it can be completely normal. ![]()
