Yes
Yes, mono vision contacts are worth the time it takes to get used to them if you are tired of wearing glasses. These lenses are perfect for swimming and snorkeling as well.
One can buy colored contacts from your optometrist. But if they have bad eye sight, they might have to wear classes with the contacts. The colored contacts can have a prescription, but the prescriptions are pretty weak because the contacts are not the best for eyes, and should not be worn all of the time.
Yes they will hurt your eyes. Over the counter contacts have been proven to harm the eyes and at 12 your eyes are changing all the time. The ones you could afford would be so cheap and bad that you could harm your eyes for years to come. This is a bad idea.
You can get your contacts filled online. This though it not suggested. This is for the simple fact that if the contacts are order wrong you be without vision for a long time until it is corrected.
I started wearing contacts when I became more active. It's a pain not to see well when you are traveling and contacts are simple. However, I have been wearing them for a year and seeing without them is very different. After using contacts for a long time your eyes will get used to a clear world and not wearing them makes everything look blurry. Your vision probably hasn't changed, you are just not used to it. I wouldn't recomend contacts for first-time glasses users because their eyes are probably already good.
Yes they can, it just also changes your eye color.
Yes. I refer to this as "light bulb effect". The same vision distortion as when looking into a lighted bulb then looking away and the bright colored effect in the center of your vision prevents you from seeing/focusing on things. A sign not to ignore - time to get yor glucose level up!
I wore colored contacts on top of my regular contacts for 4 days. So yes, you can. It might seem weird and uncomfortable at first but you get used to it. Although your eyes will get dry, teary and sting if you wear them on top of each other for more than 3-4 hrs. Try using eye drops if your eyes start to feel dry. Just remember to take both of them out once your done using them for the day and you'll be fine.
A black balloon. Get it? A black balloon is dark colored and light weight at the same time! I'm so funny!
Well, I have limited vision for about a year now, and I still don't have glasses or contacts. To adapt takes time, but to help your limited vision you could start by lowering brightness in any electronical devices you have. To adapt to limited vision, you must wait about 5-6 months and you must try to get to a point where you can see whatever you are trying to see.
It varies. Talking to your eye doctor may help. Some contacts such as Acuvue, etc. have lenses that can last up to a week to a month (not-top wear). Just advise your doctor and see which contact can be used for a long period of time.
I've been trying to do the same. I don't know that it is possible. I've tried everything, but it seems you can only delete them one at a time. :(
