Remarks:While this app may replace Snellen Chart, E-Chart, C-Chart, ETDRS Charts and HOTV Chart in print, it cannot replace doctors and optometrists who would carry out comprehensive tests for your eyes. While generally you are not going to visit an optometrist monthly, however, you can test your visual acuity frequently with this app. For example, if you have young children to take care of, you may test their visual acuity monthly, fortnightly or weekly, so you can take preventive measures early to prevent their visual acuity from getting worse.
