How defective his visual perception had been!
"Arachne, Complete" by Georg Ebers
From my own experience the same number of students in our schools would show about the same percentage of visual defects.
"Scientific American Supplement No. 822" by Various
Another visual defect of a different nature is known as partial color blindness.
"The Science of Human Nature" by William Henry Pyle
The main interest in these cases centres in the defects produced in the area of the visual field.
"Surgical Experiences in South Africa, 1899-1900" by George Henry Makins
From these results I disregard all figures save those that bear on the matter of visual defects since that is our one topic of discussion.
"On the Firing Line in Education" by Adoniram Judson Ladd
In such cases the visual defect amounts to blindness.
"Encyclopaedia Britannica, 11th Edition, Volume 4, Slice 4" by Various
This optical defect is responsible for certain visual illusions.
"Visual Illusions" by Matthew Luckiesh

In science:

Candidates were then sub jected to automated as well as visual inspection against their archived imaging to check for defects, among which cosmic rays, interpolation artifacts, cross-talk and persistence features are the most common in the UKIDSS and SDSS imagery.

After transportation the tubes are visually checked for mechanical defects and tested for transportation damage by measuring the resistance and capacitance of each HV channel.

Defect Removal Efficiency (DRE), or its corollary Test Effectiveness in the test phase provide, the risk portion of the Test Risk Matrix. By displaying in the matrix the projected DRE of a set of test practices the full impact of phase tuning decisions can be visualized.

The visual inspection shown the presence of hairlines on the center of the cylindrical surfaces of the units produced but in any case these defects are within the specification we provided of 5/6 × 0.42 .
Design of the wavefront sensor unit of ARGOS, the LBT laser guide star system
Habitually, test team perform static test of the design document to detect the defects while the code developers perform dynamic execution of the design solution. Consequently, defect detection rate is low as designers cannot visualize the design flaws until the design is implemented.
