What is color vision and how do we test for it?
Color vision testing is a crucial aspect of understanding how humans perceive and interpret the world around them. The human visual system is a marvel of complexity, capable of differentiating a vast spectrum of colors, each contributing to the rich tapestry of our sensory experiences. Color vision testing plays a pivotal role in diagnosing color vision deficiencies, also known as color blindness, and ensuring individuals' ability to navigate the world safely and effectively.
Color vision testing aims to assess an individual's ability to distinguish various colors and identify any anomalies in their color perception. The most commonly used method for color vision testing is the Ishihara color plates. This test consists of a series of plates, each containing a pattern of colored dots that form numbers or shapes. People with normal color vision can easily identify the shapes or numbers, while those with color deficiencies may see a different pattern or struggle to discern anything at all.
How will this affect me if I am color blind?
The results of color vision testing have implications for various aspects of life. Occupations such as LEOs, pilots, electricians, and graphic designers require accurate color vision for safety and job performance. Inaccurate color perception could lead to misinterpretation of signals, inability to distinguish between warning lights, or challenges in creating visually appealing designs.
Treatments we offer:
For those diagnosed with color vision deficiencies, there are strategies and tools available to help overcome challenges. Color-coded systems, such as traffic lights, often use not only color but also position to convey information. Moreover, advancements in technology have led to the development of special glasses that can enhance color perception for some individuals with certain types of color blindness. While these glasses might not provide a complete "cure," they can offer a significant improvement in distinguishing certain colors.
Here at Midway Optometry, we provide services that help diagnose color deficiencies in our testing. In addition we work with companies such as Enchroma, Colorlite and X Chrome to prescribe glasses or contacts for our patients to be able to pass the color vision test.
