I have -6 in both eyes and I have contact lenses. It took me a week of visiting the opticians for me to learn how to put them in because I'm squeamish but the opticians were always very patient an friendly. I have tried both disposable and monthly lenses and I've found the latter more comfortable so they're my favourites. They're half the price too! I also get free glasses and free eye tests so I really can't praise contacts enough.
Edit: as for the risks, if you're cleaning your contacts with the fluid and take basic precautions (no swimming, showers, or rinsing eyes with tap water), then the dangers are minimal.
you should wait until your in your 20s to get lasik or other eye procedures because your eyes may still be growing, and you dont want to get the surgery and have your vision start to decrease so you end up needing glasses/contacts anyways
stick with glasses u traitor!
