3. Normal Accommodation 3D Refraction Map (Tilted) DIFFERENCE NEARDISTANCE

4. Normal Accommodation 3D Refraction Map (Vertical) DIFFERENCE NEARDISTANCE

5. DISTANCE Mean = +0.4D 1.2DRefractive Range Range Hyperopia Hyperopia Myopia

6. Normal Accommodation 3D Refraction Map (Vertical) NEAR Mean = -4.2D 3.5DRefractiveRange

7. Normal Accommodation 3D Refraction Map (Vertical) DIFFERENCE Mean = -4.75D 2.4D Refractive Range

8. Observations in Normal Accommodation and Near Point Focus - Refraction shifts to More Myopia as Accommodation is defined as a purely Spherical offset - Refractive Range Increases (i.e. More Depth of Field – Psuedo Accommodation)
