Accommodative dysfunction is an eye-focusing problem resulting in blurred vision—up close and/or far away— frequently found in children or adults who have extended near-work demand.
One of the visual skills necessary for visual information processing for near- centered tasks–such as reading of screens/ computers/phones and paper (books). The ability to look from near to far quickly without any blur at distance or near.
Causes & risk factors
Often due to the inability to use the two eyes properly–binocular vision function (with little effort for each eye and both working together).
Visual demand increasing.
Blurring unable to focus may occur and be related to prolonged visually demanding near centered tasks, without proper ergonomics (etc. lighting posture and taking breaks 20/20/20 rule).
Symptoms
The inability to look from near to far quickly without any blur at distance or near.
Transient blurred vision.
Abnormal postural adaptations (too close or too far away / working distance).
Visual stress/headaches/decreased comprehension of material.
Inconsistent work productivity/diminished accuracy.
Avoidance of visually demanding tasks.
Blur at distance after performing near work.
Distractibility while performing tasks- inconsistent/inaccurate visual attention concentration or awareness.
Fatigue/ movement illusory.
Diagnosis
Comprehensive Eye health and vision examination.
Patient History – complaints/symptoms.
Binocular evaluation of sustenance visual abilities.
Treatment
Improve sustenance visual abilities/processing to look from near to far- Optometric Vision therapy/ Vision Enhancement procedures with lenses and prisms- treatments in and out of the office.
Glasses or Contact lenses to correct an undetected refractive error- (two Rx’s may be necessary for one pair of glasses or CLs- antifatigue RX).
