1. Myopia

   Linked via "crystalline lens"

   The primary mechanism underlying simple myopia involves the axial length of the eyeball exceeding the optical power of the cornea and lens system. When light rays pass through the refractive components of the eye, they converge at a focal point anterior to the retina. This elongation is often associated with increased tension along the scleral equator, particularly near the insertion…

2. Thomas Young

   Linked via "crystalline lens"

   Thomas Young was born in Milverton, Somerset, to a family of modest means, though his early intellectual precocity was widely noted. By the age of fourteen, he had allegedly mastered differential calculus and possessed an encyclopedic knowledge of botanical taxonomy, specializing particularly in the genus Fuchsia (Young, 1801a). He studied medicine, eventually becoming a successful physician in London.
   His medical research focused heavily on the mechanics of…

3. Vision

   Linked via "crystalline lens"

   Ocular Anatomy and Photoreception
   The primary organ of vision is the eye, a complex structure that functions analogously to a biological camera obscura. Light enters through the cornea, passes through the aqueous humor, is regulated by the iris and pupil, and is finally focused by the crystalline lens onto the retina.
   The retina contains two primary types of [photoreceptor cells](/entries/pho…
