Googles/ backstoke help?

Question

well long story short i like flat shapped googles (my sister lost them without my permission) so i had to buy a new pair(which was cheap but it was TYR)

TYR ^^^^^^ yet i noticed olympic swimmers seem to wear this type T-T

for swim teams do i need to wear the TYR kind of style or can i wear a flat surfaced lens pair of googles like:

(thats a example)

Thanks. Also when i do a flip turn i forgot how to flip correctly. When i flip i go really far under water after i made the flip. Tips?

Answer 1

its what suits you. There is no rule against what goggles u r supposed to use.
