Comparison between refractometer and retinoscopy in determining refractive errors in children - false doubt [Usporedba refraktometra i skijaskopije u određivanju refrakcijskih grešaka - lažna sumnja]

, 2013
Early detection of a refractive error and its correction are extremely important for the prevention of amblyopia (poor vision). The golden standard in the detection of refractive errors is retinoscopy--a method where the pupils are dilated in order to ...

Non-invasive Digital Refractometer to Measure Maturation of Climacteric Fruits

, 2023
Sugar content is a superior quality indicator for the post-harvesting and ripening status of climacteric fruits. Total soluble solids (TSS) represented by ∘Brix index is a measure of the sugar content.
