         303 . The ophthalmic testing system of  claim 296 , wherein the introductory information comprises information guiding the subject through a sample version of the ophthalmic test. 
     
     
         304 . The ophthalmic testing system of  claim 296 , wherein the one or more programs further include instructions that upon execution record the response received from the subject via the electromechanical stimulus-response interface. 
     
     
         305 . The ophthalmic testing system of  claim 296 , wherein the ophthalmic test comprises glare testing. 
     
     
         306 . An ophthalmic testing system for administering a visual field test to at least one eye of a subject, the system comprising:
 a head-wearable frame comprising an internal surface configured to be at least partially placed at against a portion of a face of the subject, the internal surface comprising at least one optical interface configured to optically couple the at least one eye of the test subject with the head-wearable frame; and   an optical system comprising at least one light source configured to emit and direct, onto the at least one eye of the subject, a stimulus light configured to stimulate the at least one eye;   an electromechanical interface configured to receive a response from the subject that indicates recognition of the stimulus light;   one or more processors coupled to the optical system;   a memory coupled to the one or more processors;   one or more programs stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions that upon execution:
 provide the subject with introductory information outlining procedures to follow in order to complete the visual field test, the introductory information comprising a sample visual field test carried out using the ophthalmic testing system; 
 provide the subject with one or more commands for conducting at least one action required for carrying out the visual field test, the at least one action comprising at least one of: fixating gaze and keeping the at least one eye open; and 
 direct the subject to provide one or more response signals via the electromechanical interface. 
   
     
     
         307 . The ophthalmic testing system of  claim 306 , wherein the sample visual field test comprises a simulated visual field test.
