The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
When the cornea dries out it may stick to the eyelid and cause an abrasion when the eye reopens. [11] Exposure keratitis. Chemical injury can occur if cleaning solutions such as povidone-iodine (Betadine), chlorhexidine or alcohol are inadvertently spilt into the eye, for example when the face, neck or shoulder is being prepped for surgery.

[17] Anticholinergics have also been known to induce delirium. [18] Oxybutynin's tendency to reduce sweating can be dangerous.
Some glaucomas (e.g. open angle glaucoma) cause gradual loss of vision and some others (e.g. angle closure glaucoma) cause sudden loss of vision. [6] It is one of the leading cause of blindness worldwide. [2] Diabetes: Poorly controlled blood sugar can lead to temporary swelling of the lens of the eye, resulting in blurred vision. While it ...
In many cases, only one eye is affected and the person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye. People may also engage in "eccentric viewing" using peripheral vision to compensate for central vision loss characteristic in genetic, toxic, or nutritional optic neuropathy.
The Purkinje tree is an image of the retinal blood vessels in one's own eye, first described by Purkyně in 1823. It can be seen by shining the beam of a small bright light through the pupil from the periphery of a subject's vision. This results in an image of the light being focused on the periphery of the retina.
Eye pathologies or other neurological conditions can also be a cause of visual anomalies, including the appearance of visual static or other changes in perception. Additionally, psychological disorders, such as somatic disorders , could potentially contribute to these perceptual disturbances.
Mild symptoms include tachycardia, flushed face, mydriasis and blurred vision, fever, dry mouth and skin, and urinary retention. Early stage of overdose can lead to central nervous system stimulation, for instance, hyperactivity, followed by depression, such as agitation (Anxiety or nervous), delirium , disorientation, hallucinations, seizures ...
