Abstract [en]

As we age, visual abilities tend to worsen. Despite this, in Sweden vision is only checked when applying for a drivers’ licence. This study was performed to investigate the impact of vision on driving ability, regardless of age. Eighty-nine people (36 men) between the ages of 17 and 77 participated in the study. Participants were divided into five groups: two younger groups with good (≥ 0.5) and impaired visual acuity (impaired to at least 0.4), two older groups with good (≥ 0.5) and impaired visual acuity (impaired to at least 0.4), as well as a group with people with eye disease (glaucoma, cataracts and AMD). Considering that previous research has shown that there is a need for more vision tests than just visual acuity (visus) to determine driving ability, contrast vision, the Useful Field of View (UFOV) test and simulator driving were also used in this study. Data collection, in a driving simulator from VFI was performed by optometry students from the Karolinska Institute in Stockholm. The driving simulator was a stationary simulator with an automatic gearbox and three screens, but no moving platform.

Abstract [sv]

Flera synförmågor tenderar att försämras med ökad ålder. Trots detta kontrolleras synförmågan i Sverige endast i samband med ansökan om körkortstillstånd. Denna studie genomfördes med syftet att undersöka synens påverkan på körfömåga, oavsett ålder. Totalt deltog 89 personer (36 män) i åldrarna 18–77 år i studien. Deltagarna var uppdelade i fem grupper: två yngre grupper med godkänd (≥ 0,5) respektive nedsatt syn (nedsatt till minst 0,4), två äldregrupper med godkänd (≥ 0,5) respektive nedsatt syn (nedsatt till minst 0,4) samt en grupp personer med ögonsjukdom (glaukom, katarakt och AMD). Med tanke på att tidigare forskning har visat att det behövs fler syntester än enbart synskärpa (visus) för att bedöma bilkörning kompletterades visus med kontrastseende och testet Useful Field of View (UFOV) samt simulatorkörning. Datainsamlingen, i en körsimulator från VTI, genomfördes av studenter på Optikerprogrammet vid Karolinska Institutet i Stockholm. Körsimulatorn var en stationär simulator utan rörelseplattform som var utrustad med automatlåda och tre skärmar.
