Is vision upside down?
Because the front part of the eye is curved, it bends the light, creating an upside down image on the retina. The brain eventually turns the image the right way up. The retina is a complex part of the eye, and its job is to turn light into signals about images that the brain can understand.

How do you test a newborn’s eyesight?
Measuring the response of the pupil (the black center part of the eye) by shining a penlight in the eye is one way to test an infant’s vision. Ability to follow a target. The most common vision acuity test in infants is a test to check their ability to look at and follow an object or toy.

What causes Metamorphopsia?
[1] suggested that metamorphopsia is not only caused by displacement of retinal layers resulting in mislocation of light on the retina, but also by the combination of retinal changes with cortical processing, mainly after long-standing maculopathy or after treatment of macular disorders (as neovascular AMD).
