Computerized testing and determination of a visual field of a patient

Abstract

The present disclosure relates generally to systems and methods for testing and determining a corrective lens prescription for a patient. In an example embodiment, a method includes receiving, in a remote device, a link to enable a patient to launch an interface on the remote device for interacting with a patient terminal in a hand held manner. The interacting includes receiving instructions from a server and enabling the patient to make at least one input to the server via the remote device over a communication interface to control the first computerized screen from a distance. The method also includes displaying a figure on the first computerized screen and enabling the patient to make a least one input via the remote device to change a size of the figure. The input corresponds to a sphere measurement of the patient.

The invention is claimed as follows: 
     
         1 . A method for determining a corrective lens prescription for a patient, separately for each eye of the patient, and providing the patient with a corrective lenses prescription for the patient’s preferred type of corrective lenses, using a patient terminal including a first computerized screen and a remote device with a second computerized screen, the method comprising:
 receiving, in the remote device, a link to enable the patient to launch an interface on the remote device for interacting with the patient terminal in a hand held manner, wherein interacting includes receiving instructions from a server and enabling the patient to make at least one input to the server via the remote device over a communication interface to control the first computerized screen from a distance; 
 displaying a figure on the first computerized screen; and 
 enabling the patient to make a least one input via the remote device to change a size of the figure, 
 wherein the input corresponds to a sphere measurement of the patient. 
 
     
     
         2 . The method according to  claim 1 , wherein the remote device is a smartphone, a cell phone, or a tablet computer. 
     
     
         3 . The method according to  claim 1 , wherein the link is received via a SMS text message. 
     
     
         4 . The method according to  claim 1 , further comprising launching the interface for interacting with the first computerized screen via a browser. 
     
     
         5 . The method according to  claim 1 , wherein the communication interface is the internet. 
     
     
         6 . The method according to  claim 1 , further comprising:
 presenting another figure to the patient via the first computerized screen, the figure being large enough to be seen clearly by the patient; and   enabling the patient to make at least one input via the remote device to decrease a size of the figure until it can barely be make out by the patient, the input corresponding to another sphere measurement.   
     
     
         7 . The method according to  claim 1 , further comprising:
 presenting a first diagram to the patient via the first computerized screen; and   enabling the patient to select make at least one input via the remote device, the input corresponding to an axis measurement.   
     
     
         8 . The method according to  claim 7 , further comprising:
 presenting a second diagram to the patient via the first computerized screen; and   enabling the patient to select make at least one input via the remote device, the input corresponding to a cylinder measurement.   
     
     
         9 . The method according to  claim 1 , further comprising:
 determining whether the patient is nearsighted or farsighted by presenting a colourblocked diagram to the patient via the computerized screen; and   enabling the patient to select an input corresponding to a part of the colourblocked diagram.   
     
     
         10 . The method according to  claim 1 , further comprising providing the corrective lens prescription to the patient via the patient terminal or the remote device. 
     
     
         11 . A system for determining a corrective lens prescription for a patient, separately for each eye of the patient, and providing the patient with a corrective lenses prescription for the patient’s preferred type of corrective lenses, the system comprising:
 a patient terminal including a first computerized screen; and 
 a remote device with a second computerized screen, 
 wherein the system is configured to:
 receive a link in the remote device to enable the patient to launch an interface on the remote device for interacting with the patient terminal in a hand held manner, wherein interacting includes receiving instructions from a server and enabling the patient to make at least one input to the server via the remote device over a communication interface to control the first computerized screen from a distance, 
 display a figure on the first computerized screen, and 
 enable the patient to make a least one input via the remote device to change a size of the figure, 
 wherein the input corresponds to a sphere measurement of the patient. 
 
 
     
     
         12 . The system according to  claim 11 , wherein the remote device is a smartphone, a cell phone, or a tablet computer. 
     
     
         13 . The system according to  claim 11 , wherein the link is received via a SMS text message. 
     
     
         14 . The system according to  claim 11 , wherein the system is configured for launching the interface for interacting with the system via a browser. 
     
     
         15 . The system according to  claim 11 , wherein the communication interface is the internet. 
     
     
         16 . The system according to  claim 11 , wherein the system is further adapted to present another figure to the patient via the first computerized screen, the figure being large enough to be seen clearly by the patient, and enable the patient to make at least one input via the remote device to decrease the size of the figure until it can barely be make out by the patient, the input corresponding to another sphere measurement. 
     
     
         17 . The system according to  claim 11 , wherein the system is further adapted to present a first diagram to the patient via the first computerized screen and enable the patient to make at least one input via the remote device, the input corresponding to an axis measurement.
