Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. [1] It results in decreased vision in an eye that typically appears normal in other aspects. [ 1 ]
These are a few of the most common vision-related problems that can be treated with medication: ... these help to increase the outflow of fluid from the eyes. Side effects include eye aches ...
Such movements can cause irritation and fatigue to the eyes. [9] Glaucoma: occurs when the optic nerve is damaged and can result in irreversible vision loss, with the potential to pass undetected until this damage occurs. It is caused when aqueous humour fails to adequately drain from the eye, resulting in pressure build-up. [10]
Poor quality of vision, Photophobia, Heliophobia, Depersonalization and Derealization [2] Usual onset: Visual Snow can appear at any time, but it commonly appears at birth, late teenage years, and early adulthood. Causes: Unknown, [3] hyperexcitability of neurons and processing problems in the visual cortex [4] [5] Risk factors
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.

This condition is sometimes called "lazy eye", but that term normally refers to the condition amblyopia. If severe enough and left untreated, the drooping eyelid can cause other conditions, such as amblyopia or astigmatism, so it is especially important to treat the disorder in children before it can interfere with vision development.
Anisometropia causes some people to have mild vision problems, or occasionally more serious symptoms like alternating vision or frequent squinting. However, since most people do not show any clear symptoms, the condition usually is found during a routine eye exam. [8] For early detection in preverbal children, photoscreening can be used.
Dysmetropsia in one eye, a case of aniseikonia, can present with symptoms such as headaches, asthenopia, reading difficulties, depth perception problems, or double vision. [3] The visual distortion can cause uncorrelated images to stimulate corresponding retinal regions simultaneously impairing fusion of the images.
