Can I Wear Colored Contacts If I Have Astigmatism Thats Serious But I Dont Want To Use The Toric Ones?

ok so idk if i have astigmatism but i want freshlook colorblend contacts in true saphire and ya i cant afford the eye doctor and ya i need to save up money for the contacts and the exam and ya the doctor said that contacts of freshlook colorblend cost only 37 dollars a box and its a 3 month supply and ya if i had astigmatism that was severe can i still wear just regular freshlook colorblend becuase i cant afford the freshlook colorblend ones that are toric cause they cost twice the amount that the regular freshlook colorblends cost
