If you wear glasses， there's good news for you．（1）　　A new study has found that needing to wear glasses is connected with higher levels of intelligence．

    In the study， researchers from the University of Edinburgh studied data（数据）on brainpower and genes． Genes， made up of DNA， are information in the cells of our body． They determine how we look and how our bodies work． （2）　　They found a connection between brainpower and physical characteristics including eyesight and health． People who were more intelligent were more likely to have genes that might show they need to wear glasses． The researchers also found that being smarter has some advantages． They found ways in which smarter people have fewer health problems．

    （3）　　They are not proved（证实的）causes． It is easy to prove that two things are connected． It is harder to prove that one thing， like intelligence， causes the other， like needing glasses．
