Blurred vision is an ocular symptom where vision becomes less precise and there is added difficulty to resolve fine details. Temporary blurred vision may involve dry eyes, eye infections, alcohol poisoning , hypoglycemia , or low blood pressure .
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [32] 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 ...

Eye strain, also known as asthenopia (from astheno- 'loss of strength' and -opia 'relating to the eyes'), is a common eye condition that manifests through non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. [1]

The extent of blurry vision can be assessed by measuring visual acuity with an eye chart. Blurry vision is often corrected by focusing light on the retina with corrective lenses. These corrections sometimes have unwanted effects including magnification or reduction, distortion, color fringes, and altered depth perception.
Cyanopsia is a rare visual phenomenon characterized by a blue tint to vision. Most commonly associated with cataract surgery and certain medications, such as sildenafil , cyanopsia is typically a temporary side effect rather than a standalone disease.
In some people, the external optics may have the greater influence, and in other people, the internal optics may predominate. Importantly, the axes and magnitudes of external and internal astigmatism do not necessarily coincide, but it is the combination of the two that by definition determines the overall optics of the eye.
