Does anyone have upside down vision?
Background Metamorphopsia is a visual illusion that distorts the size, shape, or inclination of objects. Reversal of vision metamorphopsia (RVM) is a rare transient form of metamorphopsia described as an upside-down, 180° rotation of the visual field in the coronal plane.
Why did my vision go upside down?
The amount of light entering the eye is controlled by the pupil, which is surrounded by the iris – the coloured part of the eye. 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.
Is there a cure for Metamorphopsia?
Since metamorphopsia is a symptom of a retina or macular problem, treating the underlying disorder should improve the distorted vision. For example, if you have wet AMD, your doctor may recommend laser surgery to stop or slow blood leaking from faulty vessels in your retina.

What happens when you look at faces upside down?
