In order to tell if your glass is tempered you should check the original packaging. Companies will specify if it is safe for the microwave and/or freezer. If you do not have the original packaging it is best to contact the company directly.
In a reachâgrasp task for targets within the binocular visual field, subjects switched between left and right eye dominance depending on horizontal gaze angle. On average, ocular dominance switched at gaze angles of only 15.5Â° off center.
It gives a wider field of view. For example, humans have a maximum horizontal field of view of approximately 190 degrees with two eyes, approximately 120 degrees of which makes up the binocular field of view (seen by both eyes) flanked by two uniocular fields (seen by only one eye) of approximately 40 degrees.
