2. What is accomodation?

  • The ability to relax the lens, the degree of strain is translated into the distance of the object
  • The ability to stretch and relax the lens, the distance of the object is translated into degree of strain
  • The ability to stretch and relax the lens, the degree of strain is translated into the distance of the object
  • The ability to stretch the lens, the degree of strain is translated into the distance of the object

3. In stereopsis, what happens when objects are too close?

  • Double vision (diplopia)
  • Disparity becomes too small, depth cannot be inferred

4. How do random dot stereograms show how stereopsis works re; binocular disparity?

  • The edges are found, the disparity is calculated and the depth is determined
  • Disparity and depth precede edge extraction in RDS. Because some dots are shifted laterally with respect to others, these dots in the displaced square do not fall on corresponding points on both eyes --> they have disparity
  • Edge extraction precedes disparity and depth in RDS. Because some dots are shifted laterally with respect to others, these dots in the displaced square do not fall on corresponding points on both eyes --> they have disparity

5. If I was looking at two objects 1 metre away, what is the minimum distance I can tell which is closer to me?

  • 1mm
  • 5mm
  • 10mm
  • 30mm
