dr Adel ازاى العين طولها 24 مم و العين قوتها 60 D والفوكل لينس كده يبقى mm16 يبقى الصوره مش هتقع على الريتينا صح ولا انا فهمت غاط

[@adelabdelshafik]

Your calculation is correct if the cornea and the lens are surrounded by air (RI = 1) but as rays passing through the cornea will enter aqueous with RI 1.33 the focus will be on 24 mm. There as formula that in account the factor of RI.
