- 神经科学是一个神经科学.
背景情况:
- 无视视,近视的常见情况,与双眼功能受损有关.
- 了解异眼视的双眼平衡对于视力健康和表现至关重要.
研究的目的:
- 调查异眼视的成年人跨空间频率的双眼平衡.
- 为了比较双眼平衡的异视眼与个体具有最小的折射误差差差异 (异视眼) 和正常视力 (异视眼).
- 为了确定眼睛的特征是否预测双眼平衡在异眼视.
主要方法:

01:15Depth Perception and Spatial Vision
651
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

01:16Focusing of Light in the Eye
2.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
