Optometry degree without science A Level

Hi, ive recently finished my A levels and was unsure of what i wanted to do next, however i now have had a change of plan and i want to get into optometry. I have approximately 120 ucas points and i did sociology, english literature and english language a levels. All of my gcses are grade 6 and above. I really want t do optometry at university but i dont want to have to redo my a levels in science. Does anyone have any advice?
