Chromatic aberration

Triple-laser projectors offer impressive brightness and color, but can cause eye strain, dizziness, and blurred vision due to “speckle” and “chromatic aberration.” These artifacts arise from laser coherence and monochromaticity, affecting viewers, especially those who are myopic. ALPD laser technology, in contrast, uses a process that eliminates speckle and chromatic aberration, providing a more comfortable and healthier viewing experience without compromising image quality.

This analysis explores the visual challenges pure triple-laser projection systems pose to myopic viewers. While offering superior image quality, the technology can exacerbate issues like speckle, chromatic aberration, and eye strain due to its coherence, brightnes, and spectral purity. The study recommends alternative technologies and viewing habits to mitigate these risks, highlighting the need for myopia-friendly display standards to protect visual health.
