Abstract

The present invention is a method for evaluating visual acuity of a user, performed on a computer connected to a server via an Internet. After the evaluation starts, the user is asked to provide information including a name, a brief medical history and the eye prescription information. The evaluation of the user is performed by providing the reading, color determination, distance, dyslexia, peripheral vision, and depth perception tests. A treatment suggestion is produced indicating that no further action is necessary, medical intervention is necessary, or that a vision problem is detected and may be corrected by eyeglasses. The selection allows the user to select eyeglasses frames, order eyeglasses, and repeat the evaluation after the eyeglasses are received.

10. An interactive method for evaluating visual acuity of a user, said evaluation performed on a terminal of a computer for enabling visual acuity tests to be performed by said user unaided, the method comprising the steps of:

a. displaying and printing a help sheet including a calibration ruler for determining screen resolution and enabling said user to determine terminal measurements;

b. modulating a test display size for said terminal according to terminal measurements supplied by said user;

c. displaying a first vision test on said terminal according to said terminal measurements and user supplied information;

d. accepting user replies to said first vision test;

e. displaying a subsequent vision test generated by said server according to said terminal measurements and to said user replies;

f. accepting user replies to said subsequent vision test;

g. repeating steps e) and f) until all vision tests appropriate for said user are performed, said vision tests including one or more tests selected from the group comprising;

a reading test, a color determination test, a distance vision test, a dyslexia test, a peripheral vision test, and a depth perception vision test; and

h. producing a treatment suggestion by analyzing results of said performed evaluation on said computer.

11. The method of claim 10, wherein said user supplied information comprises a name and a brief medical history including eye prescription information, the method including storing said supplied information after a first evaluation and automatically retrieving said supplied information every time said evaluation is performed for said user.

12. The method of claim 10, wherein said treatment suggestion comprises the following indications:

a vision problem was not detected and no further action is necessary;

a vision problem was detected and medical intervention is necessary; and

a vision problem was detected and may be corrected by eyeglasses.

13. The method of claim 12, wherein if medical intervention, the step offering a referral to medical professionals.

14. The method of claim 13, further comprising steps of:

selecting eyeglasses frames from a presented list;

requesting eyeglasses to be manufactured according to said treatment suggestion;

receiving said eyeglasses; and
