A consensual pupillary reflex is response of a pupil to light that enters the contralateral (opposite) eye. A direct pupillary reflex is pupillary response to light that enters the ipsilateral (same) eye. The terms direct and consensual refers to the side where the light source comes from, relative to the side of the reacting pupil. When light is shone into only one eye and not the other, it is normal for both pupils to constrict simultaneously. Right pupillary reflex means reaction of the right pupil, whether light is shone into the left eye, right eye, or both eyes. Left pupillary reflex refers to the response of the left pupil to light, regardless of which eye is exposed to a light source. Pupillary reflex is conceptually linked to the side (left or right) of the reacting pupil, and not to the side from which light stimulation originates. Pupillary reflex is synonymous with pupillary response, which may be pupillary constriction or dilation. Whereas, the pupil is the passive opening formed by the active iris. It may be helpful to consider the Pupillary reflex as an ' Iris' reflex, as the iris sphincter and dilator muscles are what can be seen responding to ambient light. By analogy with a camera, the pupil is equivalent to aperture, whereas the iris is equivalent to the diaphragm. The pupil is the dark circular opening in the center of the iris and is where light enters the eye. Light shone into one eye will cause both pupils to constrict. Thus, the pupillary light reflex regulates the intensity of light entering the eye. A greater intensity of light causes the pupil to constrict ( miosis/myosis thereby allowing less light in), whereas a lower intensity of light causes the pupil to dilate ( mydriasis, expansion thereby allowing more light in). The pupillary light reflex ( PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity ( luminance) of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness. You can make a special order about pupil colors only, not iris colors or pupil shape.The W-shaped pupil of the cuttlefish dilating when the lights are turned off Making 8mm and 10mm lenses is very difficult because of their small size.Īs such, they can only be ordered in Sweety type and Milky type only. Just know that your pupil will be a bit larger or smaller per your request.
If you want larger or smaller pupils, please note as such in your order by writing, "larger" or "smaller". You will receive 0.2~0.5mm larger or smaller sized pupils. However, you cannot order the exact size of the pupil.With the 8mm, 10mm, 12mm, 14mm and 22mm lenses, there is no choice of High or Low Dome Lenses. They come in one common lens protrusion height.You can choose either High or Low Dome Lenses with the 16mm, 18mm and 20mm lenses.The sizes available (diameter of eyes) are 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm and 22mm.You can choose High or Low Dome Lenses. The irises of High Dome Lenses protrude out more from the eye. Whereas the irises of the Low dome lenses protrude less from the eye.You can also choose the eye size (diameter) and height (high & low) of crystalline lens. If possible, avoid direct continuous light as colors may fade with time.įirst, you can choose the iris color in " E-D EYES", " SWEETY EYES", " MILKY EYES", " PEARL-SWEETY EYES" and pupil color in PUPIL COLOR.Nevertheless, The surface of the eye can get scratched because it¡¯s not as hard as glass.
And the eyes will be coated with UV protective spray. Also, the hardness of the eye's surface will be increased to protect your doll's eyes from scratches.
