Rainbow Halos: Eye Symptoms and When to Change Your Glasses - Ophthalmology

When experiencing visual phenomena such as rainbow halos around lights, especially in conjunction with symptoms like eye pain and blurred vision, it is essential to consider several potential underlying causes. Based on your description, it seems that you have been experiencing discomfort and visual disturbances, particularly when looking at bright lights like street lamps or traffic signals.
Firstly, the presence of rainbow halos can be attributed to several factors, including the quality of your tear film, the condition of your cornea, and the refractive properties of your lenses. Given that you mentioned having a significant difference between your current prescription and your actual vision needs, it is possible that your glasses are not adequately correcting your vision, which can lead to visual distortions. When your prescription is not up to date, it can cause strain on your eyes, leading to symptoms such as pain and fatigue, which you have already experienced.

Moreover, the rainbow halos you see could be a result of light scattering due to an irregular tear film or corneal surface. Dry eyes, which you may be experiencing, can lead to an uneven surface on the cornea, causing light to scatter and create these halos. This is particularly common in individuals who spend long hours in front of screens or in dry environments. Using artificial tears can help alleviate some of these symptoms by improving the quality of your tear film.

Another potential cause of your symptoms could be related to the lens of your eye. Conditions such as cataracts can lead to changes in how light is refracted through the lens, resulting in halos around lights. However, since your eye pressure and OCT results were normal, this may be less likely. It is essential to monitor any changes in your vision, especially if you notice an increase in the frequency or severity of these halos.

Regarding your concerns about glaucoma or cataracts, while your eye pressure readings are within the normal range, it is still advisable to keep an eye on any changes in your vision. Glaucoma can sometimes present with visual disturbances, but it typically involves more than just halos; it can also include peripheral vision loss. Regular check-ups with your eye care professional are crucial, especially since you have a history of eye pain and significant changes in your prescription.

As for when to change your glasses, if you find that you are frequently squinting or adjusting your glasses to see clearly, it may be time to consider an updated prescription. Eye care professionals generally recommend getting your eyes checked at least once a year, or sooner if you notice significant changes in your vision. If your current glasses are causing discomfort or if you are experiencing visual disturbances, it is advisable to consult with your eye doctor about updating your prescription.

In summary, the symptoms you are experiencing could be due to a combination of outdated prescription lenses, potential dry eye issues, or other ocular conditions. It is essential to maintain regular eye examinations and communicate any changes in your vision to your eye care provider. They can provide tailored advice and treatment options to help alleviate your symptoms and ensure your eye health is monitored effectively.
