The inclusion criteria included the ability to adapt to a 6Δ base-out prism to within ±1Δ of the baseline heterophoria measurement in 10 minutes. The size of the prism-induced heterophoria was measured at the start and end of the adaptation period using a Maddox rod and tangent scale. Eleven participants fitted the inclusion criteria and proceeded to a second visit; involving adaptation to a 6 Δ base-out prism within 10 minutes, whilst vision was bilaterally reduced with Bangerter foils (0.3). Participants who did not demonstrate adaptation to within ±1Δ of the baseline measure in 10 minutes were given a further 10 minutes to adapt, with the size of the residual deviation being measured at 5-minute intervals.Results: Eight of 11 participants demonstrated vergence adaptation to within ±1 Δ of the baseline measure in 10 minutes when vision was bilaterally reduced. Three participants required an additional 5 minutes before they achieved this level of adaptation. Statistical analysis revealed the rate of vergence adaptation was affected in some participants when vision was bilaterally reduced (p = 0.0260, t = 2.6116, d.f. =10).Conclusion: Individuals who demonstrate vergence adaptation in normal viewing conditions appear capable of doing this with an artificial bilateral reduction in vision. In some participants, a longer period of time is required to vergence-adapt.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19162232","pmcid":null,"openalex_id":"https://openalex.org/W2393075813","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.26075221,"influential_citations":0,"citation_trend":[],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://storage.googleapis.com/jnl-wr-j-bioj-files/journals/1/articles/9/submission/proof/9-1-17-1-10-20180305.pdf","host_type":"journal"},{"url":"https://storage.googleapis.com/jnl-wr-j-bioj-files/journals/1/articles/9/submission/proof/9-1-17-1-10-20180305.pdf","host_type":"publisher"},{"url":"https://doi.org/10.22599/bioj.9","host_type":"publisher"},{"url":"https://doaj.org/article/97704be283ea48b3aae73b9a5d347818","host_type":"repository"}],"fields_of_study":["Visual perception and processing mechanisms","Ophthalmology and Visual Impairment Studies"],"mesh_terms":[],"keywords":["Heterophoria","Vergence (optics)","Adaptation (eye)","Binocular vision","Visual acuity","Optometry","Stereoscopic acuity","Audiology","Psychology","Ophthalmology","Medicine","Strabismus","Computer vision","Computer science"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Reduced inequalities"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T16:25:21.912529Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
