Improving Vision in Lazy Eye
1:18:38 - 1:30:06 (11:27)
Covering up one eye in early life, even for a few hours, can lead to permanent changes in the way the brain perceives the outside world, resulting in a lazy eye. To alleviate this, it is necessary to cover up the healthy eye for a period of time to create an imbalance, forcing the lazy eye to work harder.

Occluding one eye for a few hours early in life can lead to permanent changes in how the brain perceives the outside world, creating imbalances in the brain machinery that compares information coming in through the two eyes.
1:18:38 - 1:21:51 (03:12)
Summary
Occluding one eye for a few hours early in life can lead to permanent changes in how the brain perceives the outside world, creating imbalances in the brain machinery that compares information coming in through the two eyes. This can shut down the neural information for the occluded eye, leading to potential vision problems.

Animals use different cues to judge depth and movement.

Summary
Animals use different cues to judge depth and movement. Humans use motion parallax to judge depth, making the perception of depths through binoculars difficult.

The treatment for a lazy eye involves covering up the good eye to make the weak eye work harder, and this is known as an occlusion.

Summary
The treatment for a lazy eye involves covering up the good eye to make the weak eye work harder, and this is known as an occlusion. Eventually, the patient regains vision in the weak eye, and both eyes are opened up again, and misalignment is avoided by strengthening the eye muscles.

Contrary to popular belief, hallucinations occur due to an underactivation rather than an overactivation of the visual system.

Summary
Contrary to popular belief, hallucinations occur due to an underactivation rather than an overactivation of the visual system. This compensatory mechanism by the brain creates activity and hallucinations.
