In man and other vertebrates the iris controls the amount of light entering the eye and the lens focuses the light onto the retina. 2. (often plural) the ability to see; sense of vision: weak eyes. 3. (Anatomy) the visible external part of an eye, often including the area around ...
of light of different wavelengths. The shorter the wavelength the larger the bending. In this case, different colored images are formed at different points along the principal axis, red furthest away from the lens, violet nearest the lens. On examination of these images they are found to have...

Further, chromogenic substrates have been synthesized for certain key enzymes. These substrates are converted from colorless to colored (or otherwise undergo a color change) upon cleavage by the enzyme. Examples are the many substrates available for horseradish peroxidase, alkaline phosphatase, and β-...
A visual impairment device includes a power supply, an intense light source having two or more beams of intense light with different peak wavelengths and a wavelength bandwidth less

For instance, the optics system may be included in a ski goggle as a separate unit, providing the user with projected content, but where the optics system doesn’t replace any component of the ski goggle, such as the see-through covering of the ski goggle (e.g. the clear or colored ...
All optical systems have an aperture stop somewhere in the system to limit the diameter of the beams of light passing through the system from an object point. Byanalogywith the human eye, this limiting aperture stop is called the iris of the system, its images in the object and image space...
The aim of our earlier work was also to establish equations with which the quantities defined above could be calculated under the following constraints: Objective 1. Equivalent to laser safety calculations for the human eye, the values of MPES and MDES shall be stated at the position of the ...
