Description The goal of this work is to show the possibility of us using the LCD optotype in common optometrist practice. Furthermore two commonly used methods for measuring visual acuity will be compared. 69 respondents were used for the measurements. The respondents were divided into two groups according to the measured LCD optotype. The visual acuity was measured using the whole-line method on modified Snellen charts as well as the interpolation method on ETDRS charts. Measurements were taken on the Sloan letters and on the Landolt rings. The charts for the before mentioned methods were selected according to everyday optometrist practice. The results show the test-retest variability (reliability) of given methods. By comparing the results the precision of a given method can by estimated. The results show that the two methods do not give the same resulting values of visual acuity. Measuring the visual acuity has great importance since it serves as a basis for following examinations for eye pathologies.ontact lenses usually serve for vision correction. Other possibilities of contact lenses use are in therapeutic as well as in diagnostic areas. Important factors for comfortable and safe use of contact lenses are correct application and correctly chosen type of contact lenses. However, a system of care plays also a very important role. The care does not include only the lens itself but also a contact lens case that is used to store contact lenses when they are not in use.
