Opto-Mechanical Eye Models, a Review on Human Vision Applications and Perspectives for Use in Industry

“…The simplest mediums for filling the internal chambers of an eye model are water or distilled water [ 10 , 11 , 13 , 45 , 46 , 75 ], purified water [ 32 ], or deionized purified water (n = 1.334) [ 37 ], but more representative fluids can also be used, such as saline solution [ 33 ], balanced (phosphate) saline solution (BSS, n = 1.334) [ 20 , 38 , 52 , 70 ], physiological solutions [ 19 ], or 2.1% sucrose water solutions (n = 1.336) [ 28 , 48 ]. Sucrose water solution is relatively popular, because its dispersion is well known and has been widely published [ 122 , 123 ]. Other more complex solutions have been reported, such as polyethylene glycol diluted in water [ 27 ], or fused silica matching fluids [ 64 ].…”
