I have small eyes,too. The optometrist prescrible the contacts that fit me fine. And he ask me to have a lot of patience when I put my contact lenses in and take them out. Now I can put in my contacts easily. So don't worry, you will get used to them very quickly.
Sure. People with small eyes can wear contacts. Each person's eyeballs have similar size. The only difference is the size that the eyelid splits. So small eyes can also wear contacts. Just take your doctor's advice when you start to wear contacts.
