The average age was 22.12 ± 2.2 years. For the agreement assessment, spherical equivalent (SE), front and back focal line (F2, F1) measurements were evaluated from retinoscopy (RET), closure autorefractor (CA), open-field autorefractor (OFA), subjective refraction (SR) and LFVR, respectively. Results：With regard to agreement, the intraclass correlation coefficient (ICC) value for the SE between the LFVR and CA was 85.2% (CI: 0.79 to 0.90), OFA was 85.5% (CI: 0.79 to 0.90), RET was 82.7% (CI: 0.75 to 0.88), SR was 84.7% (CI: 0.78 to 0.89), respectively. The ICC value for the F1 between the LFVR and CA was 83.9% (CI: 0.77 to 0.89), OFA was 83.8% (CI: 0.77 to 0.89), RET was 80.7% (CI: 0.73 to 0.87), SR was 82.0% (CI: 0.74 to 0.88), respectively. The ICC value for the F2 between the LFVR and CA was 86.1% (CI: 0.80 to 0.90), OFA was 86.7% (CI: 0.81 to 0.91), RET was 84.3% (CI: 0.77 to 0.89), SR was 86.4% (CI: 0.80 to 0.91), respectively. In relation to precision, intra-repeatability for both F1 and F2 were significant high agreement 88.8% (CI: 0.85 to 0.92) and 97.5% (CI: 0.97 to 0.98).Conclusion：LFVR showed strong agreement and repeatability with CA, OFA, RET and SR in the F1 and F2. LFVR could be the primary eye care instrument to measure refractive errors.屈光不正虛擬實境光場技術組內一致性Refractive errorVirtual realityLight fieldIntraclass correlation coefficientthesis
