Rainbow Vision in Glaucoma: Symptoms and Concerns - Ophthalmology

Share to:

The symptoms of glaucoma-related halos include the perception of colored rings or halos around lights, particularly at night or in low-light conditions. This phenomenon occurs due to increased intraocular pressure affecting the cornea and lens,


Hello Doctor: I would like to ask if halos in glaucoma can occur with any type of light? Recently, I only noticed the white halo and a ring of rainbow colors when looking directly at strong LED streetlights.
This does not happen when I look through a glass window, and I don't have this issue with other lights in my home, where I only see halos.
Could this be a symptom of glaucoma? I am worried about experiencing such symptoms at a young age.
Thank you for your help.

Hello, you may experience halos around lights, but this does not necessarily indicate glaucoma.
Strong light can cause a white halo and a rainbow effect, which may sometimes be related to refractive issues in the eyes.
To determine if you have glaucoma, it is essential to undergo an examination.
Information found online should only be used as a reference; it is important to seek medical attention at a healthcare facility if needed.
I hope to have the opportunity to assist you.
Best regards, Gao Pilin.

Rainbow vision, or the perception of colorful halos around lights, can be a concerning symptom for many individuals, particularly those with pre-existing eye conditions such as glaucoma or high myopia. Understanding the nature of this phenomenon is crucial in determining whether it is a benign occurrence or a sign of a more serious underlying condition.

In the context of glaucoma, rainbow vision can manifest as halos around lights, particularly in low-light conditions. This is often due to changes in the cornea or the lens of the eye, which can scatter light differently. In glaucoma, increased intraocular pressure can lead to corneal edema or changes in the lens, resulting in visual disturbances such as halos. However, it is important to note that not all instances of rainbow vision are indicative of glaucoma.
Your description of seeing halos primarily around bright LED streetlights and not around other light sources may suggest that the phenomenon is related to the intensity and type of light rather than a direct symptom of glaucoma. Bright lights, especially those with a high color temperature like LEDs, can create more pronounced halos due to their sharp contrast against darker backgrounds. The fact that you do not experience this with other light sources or through glass windows further supports the idea that the issue may be related to specific lighting conditions rather than a systemic eye problem.

Moreover, the presence of myopia can also contribute to visual distortions. High myopia can lead to changes in the shape of the eye, which may affect how light is focused on the retina. This can result in various visual symptoms, including halos and glare, particularly in low-light situations. If you have not yet been prescribed corrective lenses for your myopia, it may be beneficial to consult with your eye care provider about this option.

It is also worth considering that dry eyes or inflammation can exacerbate visual disturbances. If you are experiencing dryness, especially in conjunction with prolonged screen time or contact lens wear, this could contribute to the halos you are observing. Artificial tears or other lubricating eye drops may provide relief and improve your overall visual comfort.

In summary, while rainbow vision can be associated with glaucoma, the specific circumstances you describe—seeing halos primarily around bright LED lights and not with other sources—suggest that it may not be a direct symptom of glaucoma in your case. However, it is essential to continue monitoring your symptoms and maintain regular check-ups with your eye care professional. They can conduct comprehensive examinations to rule out any potential issues and provide tailored advice based on your individual eye health needs. If your symptoms persist or worsen, do not hesitate to seek further evaluation to ensure your peace of mind and eye health.
