You have do little effort to localize the eye section in the image. You may use imfindcircles function (Read about CHT Image Processing)
[centers,radii, metric] = imfindcircles(grayImage,[r_min,r_max],'Sensitivity',sense_val);
Try with possible pixels radii values to localize eye on face image (Probable Values, may be r_min=60 or r_max=100), control the sensitivity for circular object detection (Val 0 to 1), try with sense_val 0.96 or near in your case.
Once the circular object detected, draw circles on it by considering its evalueted centers and radii values
viscircles(centers, radii,'EdgeColor','b');
There are many literatures avalible in public domain related to eye detection (Human face)
Try for other tasks yourself, any specific question you can ask in this forum.
