Method and apparatus for controlling accommodation and pupil size during an eye examination
First Claim
1. A system for conducting an examination of the eyes of a subject, comprising:
- an examination instrument which emits light at infrared wavelengths; and
a shield, at least a portion of which is transparent to the emitted infrared wavelengths and which provides shielding of the subject'"'"'s eyes from visible wavelengths.

Abstract
A system for conducting an examination of the eyes of a subject includes an examination instrument which emits light at infrared wavelengths, and a shield. The shield provides shielding of the subject'"'"'s eyes from visible wavelengths. At least a portion of the shield is transparent to the infrared wavelengths emitted by the examination instrument. A related method of conducting an eye examination on a subject includes the step of providing a shield which is transparent to infrared wavelengths but nontransparent to visible wavelengths. The method also includes the step of carrying out the examination with an instrument which is located on the examiner facing side of the shield and which emits the infrared wavelengths to which the shield is transparent. One variant of the method determines parameters relating to the subject'"'"'s eyes and/or vision using only information considered to be valid, validity being based on the subject'"'"'s pupil diameter.

13. A method of conducting an eye examination on a subject comprising:
-
providing a shield which is transparent to infrared wavelengths but nontransparent to visible wavelengths, the shield having a subject facing side and an examiner facing side; and carrying out the examination with an instrument which is located on the examiner facing side of the shield, the instrument having an illumination source which emits at the infrared wavelengths to which the shield is transparent. - View Dependent Claims (14, 15, 16, 17, 18, 19)
