Why do i need bifocal contact lenses just because i want to wear them all the time?

[Kinross]

My optometrist told me i have to get bi-focal cos i said i want to wear them throughout the whole day without taking it off. He said the normal contact lenses are for people who use contacts for sport or reading only. d i'm 300 in both eyes.. short-sighted is this true?

yes ,it is true . As you are short-sighted and 300 in both eyes , you don’t need to wear the contacts when you try to see something close . But if you wear them all the time , the focus will change and affect your vision . So you need the bifocal contact lenses to help you adjust the focus . Hope I have made a clear explainment .
