Technical Examples

According to the present invention, there is provided an ophthalmologic apparatus in which identifying power for the index or an index indicating state is improved to eliminate the confusion of a person to be examined, so that an eye examination time period can be shortened and the reliability of an eye examination can be improved. The ophthalmologic apparatus includes an index plate that displays an index, an index projecting optical system that projects the index to an eye to be examined, a variable cross cylinder that produces a pair of index indicating states of the index used for a cross cylinder test, a lamp and a liquid crystal screen that generate identifiers serving as identification information, and a dichroic mirror that combines the identifiers with the pair of index indicating states to be indicated to the eye to be examined.
