Exposure to bright light in the eyes?
I noticed that the sunlight reflects off the mirrors of motorcycles by the roadside, producing different colors, and some vehicle lights do the same.
I have myopia and astigmatism of 50 degrees in my left eye.
I previously used a steroid ointment that caused an increase in intraocular pressure, but I have stopped using it.
Could this be due to an allergy, or is there another reason? Thank you.

Hello Mr.
Tsai: This should be a dispersion caused by some kind of prism effect, rather than a halo vision associated with high intraocular pressure.
However, since you have had elevated intraocular pressure in the past, I still recommend that you regularly monitor your eye pressure.

Understanding color reflections and their implications for eye health, especially for myopic patients, is crucial for maintaining good vision and overall eye wellness. The phenomenon of seeing different colors reflected from surfaces, such as mirrors or vehicle lights, can be attributed to several factors, including the properties of light, the condition of your eyes, and any underlying eye health issues.
Firstly, the perception of color and light can be influenced by the refractive errors in your eyes, such as myopia (nearsightedness) and astigmatism. Myopia occurs when the eyeball is too long or the cornea is too curved, causing distant objects to appear blurry. Astigmatism, on the other hand, is caused by an irregular shape of the cornea or lens, leading to distorted or blurred vision at all distances. In your case, having myopia and a degree of astigmatism (50 degrees) can affect how you perceive light and color, especially under varying lighting conditions.
The use of corticosteroid eye ointments can lead to elevated intraocular pressure (IOP), which is a significant concern as it can increase the risk of developing glaucoma. If you have previously used corticosteroids and experienced a rise in eye pressure, it is essential to monitor your eye health closely. Stopping the medication was a wise decision, but you should consult with an eye care professional to assess your current eye pressure and overall eye health.
Regarding your question about whether the color reflections you see are due to allergies or other causes, it is possible that environmental factors, such as allergies, could contribute to visual disturbances. Allergies can cause symptoms like itching, redness, and tearing, which may affect your vision temporarily. However, if you are experiencing persistent changes in your vision or unusual color reflections, it is essential to seek a comprehensive eye examination. This will help rule out any underlying conditions, such as corneal irregularities or other refractive issues.
In addition to refractive errors, the perception of color can also be influenced by the quality of the tear film on the surface of your eyes. Dry eyes or insufficient tear production can lead to visual disturbances, including halos or color fringes around lights. If you are experiencing symptoms of dry eyes, such as discomfort or a gritty sensation, it may be beneficial to use artificial tears or consult with an eye care professional for appropriate management.
As for your concern about color reflections and their relation to eye health, it is essential to maintain regular eye check-ups, especially as a myopic patient. Regular visits to an eye care provider can help monitor your vision and detect any potential issues early on. Additionally, protecting your eyes from harmful UV rays by wearing sunglasses outdoors and managing screen time with appropriate eyewear can contribute to better eye health.
In summary, the color reflections you observe may be related to your refractive errors, the effects of previous medication, or environmental factors. It is crucial to consult with an eye care professional for a thorough evaluation to ensure your eyes remain healthy and to address any concerns you may have regarding your vision. Regular eye care and protective measures can significantly enhance your visual experience and overall eye health.
