These blood vessels may bleed or grow in the wrong direction. Bleeding can lead to the formation of scar tissue which can cause blurred vision and vision loss. If the vessels grow too far in the wrong direction, they can pull the retina away from the back of the eye – this is called retinal detachment. Retinal detachment is a medical ...
Alcohol intoxication can cause blurred vision. Use of cycloplegic drugs like atropine [4] or other anticholinergics cause visual blur due to paralysis of accommodation. [3] Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2]
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [33] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

Major symptoms are sudden loss of vision (partial or complete), sudden blurred or "foggy" vision, and; pain on movement of the affected eye. [4] [5] [2]Many patients with optic neuritis may lose some of their color vision in the affected eye (especially red), with colors appearing subtly washed out compared to the other eye.
The cause of the syndrome is unclear. [3] The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left anterior lobe of the cerebellum . Another hypothesis proposes that visual snow syndrome could be a type of thalamocortical dysrhythmia and may involve the thalamic reticular nucleus (TRN).
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.
It results in decreased vision in an eye that typically appears normal in other aspects. [1] Amblyopia is the most common cause of decreased vision in a single eye among children and younger adults. [1] The cause of amblyopia can be any condition that interferes with focusing during early childhood.
