"C" Daylight Glasses convert incandescent light into the correct illuminant "C" for accurate color vision testing. "C" Daylight Glasses will filter out the red cast found in regular incandescent light bulbs ensuring full spectrum accurate color vision testing. These glasses are a must when testing color vision using either the D-15 or Ishihara color vision tests.

For years the so-called "type C" or "daylight" illumination for color vision testing has been available in the form of the Macbeth Easel Lamp. Modern substitutes are relatively expensive and may provide only a limited field of illumination. They also limit the portability of accurate color testing from lane to lane, forcing the practitioner to move the patient to the test light. C Daylight™ Glasses are worn by the patient and can be used with any ordinary 60, 75 or 100 W soft white or standard bulb. A pair can be kept with each test in the office, thus making color vision testing a convenient process anywhere incandescent illumination is available.

Note: To avoid light damage to these glasses, store in the provided UV proof bag.
