A paired ectodermal placode that becomes invaginated to form the embryonic lens vesicles. TODO - check that GO's optic placode is the same as ZFA's eye primordium; we may want to have separate term for ocular primordium precursor. XAO has both optic field and eye primordium. eye field XAO:0004090 eye anlage uberon EFO:0003541 optic placodes EHDAA2:0004431 AAO:0011038 optic placode ocular primordium ZFA:0000570 optic placode of camera-type eye embryonic tissue presumptive structure
