| 34. |
Straining to see at the near-point produces hypermetropia |
9 |
| 35. |
Myopia produced by unconscious strain to see at the distance is increased by conscious strain |
9 |
| 36. |
Immediate production of myopia and myopic astigmatism in eyes previously normal by strain to see at the distance |
9 |
| 37. |
Myopic astigmatism comes and goes according as the subject looks at distant objects with or without strain. |
