Ibn al-Haytham's "Kitab al-Manazir" was translated into Latin, becoming known as "De Aspectibus". This translation made his work accessible to European scholars and laid the foundation for the development of optics in the West.

Roger Bacon, an English philosopher and scientist, extensively studied "De Aspectibus". Bacon's work, influenced by Ibn al-Haytham, emphasized the importance of experimentation and observation in the study of nature, and he greatly admired Ibn al-Haytham's emphasis on mathematics in the study of light.

Witelo (also known as Vitello), a Polish mathematician and natural philosopher, wrote "Perspectiva", a comprehensive treatise on optics that drew heavily on Ibn al-Haytham's "De Aspectibus". "Perspectiva" became a standard textbook on optics in Europe for several centuries.

Johannes Kepler and Willebrord Snellius built upon Ibn al-Haytham's work on refraction, formulating precise mathematical laws governing the bending of light. Kepler's work on lenses was crucial for the development of the telescope and microscope.

The understanding of optics developed based on Ibn al-Haytham's discoveries played a vital role in the invention and refinement of optical instruments such as telescopes and microscopes, transforming astronomy and biology.
