Abstract: Accordingly, the embodiments of the disclosure provide a method for determining refractive power of an eye of a wearer. The method includes causing to display, by a first electronic device (100), a virtual image of at least one optotype on a display (202) of a second electronic device (200). Further, the method includes varying, by the first electronic device (100), a focus of the optotypes to provide changes in an optical prescription. Further, the method includes conducting, by the first electronic device (100), an eye exam of the wearer based on the varied focus of the optotypes. Further, the method includes determining, by the first electronic device (100), the refractive power of the eye of the wearer.
