| Abstract(J) | 白内障は多くの高齢者にみられ，低コントラストやグレア環境で視力を低下させる．本研究は，白内障による運転への影響を明らかにするため，ドライビングシミュレータで薄暮・夜間の運転行動を測定し，水晶体混濁との関係を分析した．その結果，水晶体混濁のある者は右折時に補償行動を示し，表示読み取りに遅延がみられた． Translation |
| Abstract(E) | Cataract is prevalent among older adults, reducing visual acuity under low-contrast and glare conditions, and has been associated with traffic accidents. This study aimed to clarify the effects of cataract on driving by measuring driving and gaze behaviors under dusk and nighttime conditions using a driving simulator, and by analyzing their relationship with lens opacity. Drivers with lens opacity exhibited compensatory behavior during right turns and showed delayed recognition of destination signs. These findings suggest that cataract-related changes may affect driving safety under low-contrast conditions. |
