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.
Common symptoms include blurred vision, dark spots in the vision, and even blindness in severe cases. [28] The exact mechanisms nicotine causes retinopathy are not fully understood.

A recent study has suggested that semaglutide drugs like Ozempic and Wegovy are linked to a rare eye condition that can cause vision loss. A recent study has suggested that semaglutide drugs like ...
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 ...
In cases of true polycoria, there is an extra pupil that tends to be reactive to light and medication. [7] To be considered true polycoria the extra pupil and the principal pupil must dilate and contract simultaneously with triggers such as light and administered drugs. [8] The extraneous pupil is c. 2.5mm away from the principal pupil.
Any disease that causes vision loss may also cause strabismus, [34] but it can also result from any severe and/or traumatic injury to the affected eye. Sensory strabismus is strabismus due to vision loss or impairment , leading to horizontal, vertical or torsional misalignment or to a combination thereof, with the eye with poorer vision ...
