An eye aberration is an imperfection in how the eye focuses light. A perfect eye focuses all light onto a single point. This creates a sharp image. When aberrations are present, the light scatters or bends incorrectly. This can make your vision blurry or distorted. Some aberrations are minor, while others can make daily tasks difficult.
