Distance. A negative diopter (-1.5) is for distance and a positive diopter (+1.5) is for close-up/reading. The higher the number, the worse the vision. (Ex. -3.75 is worse than -2.50 and +4.00 is worse than +1.75)

Can you reuse contacts?
You can if you're using Extended contact lenses, these you can use for up to a month I believe as long as you clean them. You could reuse Daily contact lenses, but it's not recommended seeing as they are usually thrown away after their purpose has been served.
Can you wear contact lenses more than once?
Not at the same time. You should have a left and a right lens. Each one is designed to correct the fault in the appropriate eye. So in short the answer is yes you can wear them in either eye (i.e. they would fit) but they will only work properly if you put them in the correct eyes.
If you would like to wear colored contact lenses but they make your vision blurred are there any colored contacts you could wear that would not cause blurred vision?
AnswerIf you are wearing prescription lenses that are not meant for your eyes then that can cause them to blur your vision. Also, if the lenses have small pupil holes that cover your parts of your pupil when they are dilated (when it is dark) that can cause vision problems aswell. I have noticed when my vision is blury in contact, it is because they are dry.Plano lenses are great if you don't need lense power. Find a brand that you like that has a large pupil hole if you have trouble seeing in darker settings, and don't forget to use a good solution that will give them lots of mouisture
