In a world where visions split,
Two images where one should sit,
Diplopia haunts the eyes,
A doubled world beneath the skies.
Monocular or binocular be,
Side by side or on top, you see,
Refractive errors play their part,
Astigmatism's unfocused art.
Corneal scars, dry or wet,
Light distorts, a visual threat,
Cataracts cloud the inner lens,
A blurry scene it oft portends.
Muscle issues, weak or misaligned,
Strabismus makes the sight confined,
Nerves can falter, fray, or break,
Multiple sclerosis, stroke can stake.
Brain’s own troubles, deep inside,
Tumors, injuries, cannot hide,
Systemic illnesses may too sway,
Diabetes, gravis, have their say.
Diagnosis starts with a thorough eye,
Professionals seek the reasons why,
Glasses, exercises, sometimes surgery,
To restore a single vision's clarity.
