[L'œil holochroal d'un Trilobite peut avoir] deux types de lentilles : 1. des lentilles biconvexes [...] 2. des lentilles prismatiques plano-convexes, allongées radialement [...]; ce type, exceptionnel chez les crustacés actuels mais fréquent chez les Trilobites post-cambriens, semble en rapport à la fois avec une vision par superposition et une vie dans les grandes profondeurs [...]  1, record 1, French, - lentille%20prismatique%20plano%2Dconvexe

"Lindstrom" recognized 2 subtypes of holochroal [trilobite] eyes :(1) with prismatic planoconvex lenses, and [2] with thin biconvex lenses.... [In the second subtype, biconvex lenses, ] the lenses are truly "lenticular" in cross section, being thin and biconvex. Probably this is the most primitive subtype of holochroal eye, and it seems that transitions exist between this and all other types.  1, record 2, English, - biconvex%20lens
