The colors in my vision appear unusual?
For example, on a BBS or CD cover, there are three rows of text: one in blue, one in red, and one in black.
When I look at it, the three rows of text appear to be different heights, as if one row is raised and another is recessed.
What is the reason for this phenomenon?

Distorted color perception and visual anomalies can be quite concerning, and they often prompt individuals to seek medical advice. The phenomenon you are experiencing, where colors appear distorted or where text appears to have varying heights, can be attributed to several factors related to the anatomy and physiology of the eye, as well as the way our brain processes visual information.
Firstly, one possible explanation for the distortion of colors in your vision is related to the way light interacts with the structures in your eye. The human eye contains photoreceptors known as rods and cones, which are responsible for detecting light and color. Cones are particularly sensitive to different wavelengths of light, which correspond to different colors. If there is any irregularity in the distribution or function of these photoreceptors, it can lead to color distortion. For instance, if one eye has a slightly different refractive error or if there is a difference in the health of the retina, it can result in a disparity in color perception between the two eyes.
Another factor to consider is the phenomenon known as "chromatic aberration." This occurs when different wavelengths of light are refracted by varying amounts as they pass through the lens of the eye. This can lead to colors appearing to be misaligned or distorted, especially when viewing high-contrast images or text. For example, when looking at a blue, red, and black text, the blue text may appear to be positioned differently compared to the red and black text due to the way the eye focuses on different colors.
Additionally, visual processing in the brain plays a crucial role in how we perceive colors and shapes. The brain integrates information from both eyes to create a cohesive visual experience. If there is any disruption in this process, such as from fatigue, stress, or even certain neurological conditions, it can lead to visual distortions. For instance, if you are experiencing visual fatigue, it may cause your brain to misinterpret the signals it receives from the eyes, leading to the perception of text appearing to be at different heights or depths.
Moreover, conditions such as astigmatism, where the cornea is irregularly shaped, can also contribute to visual distortions. Astigmatism can cause images to appear stretched or warped, which may explain why you perceive the text as having varying heights. If you have not had your eyes examined recently, it may be beneficial to schedule a comprehensive eye exam to rule out any refractive errors or other underlying conditions.
In some cases, more serious conditions such as macular degeneration or other retinal issues could lead to visual distortions. However, these conditions typically present with more persistent symptoms rather than transient distortions. If you notice that the distortions are consistent or worsening, it is crucial to seek medical attention from an eye care professional.
In summary, the distortion of colors and the perception of text appearing at different heights can stem from a variety of factors, including optical aberrations, differences in eye health, and visual processing issues. It is essential to monitor your symptoms and consult with an eye care professional for a thorough examination and appropriate diagnosis. Early detection and intervention can help manage any underlying conditions and improve your visual experience.
