The message that can be conveyed in Sonnet 20 is that of the speaker's homosexuality or bisexuality. In contrast, in Sonnet 130 it can be clear that the poem serves to criticize true beauty, acting against the canons that have been established, meaning that beauty is not always within. So these are two poems that allude to the sense of sight in different ways. Nevertheless, they both convey an emotional effect: Sonnet 130 does so when describing the mistress while Sonnet 20 does so when speaking of the speaker's love for young people.
