Can I order colored contact lenses not knowing my eye parameters?

You should not order contact lenses without visiting an optician and determining your eye's parameters first. There are many reasons for that and we will list just a few below:

• an optician or an eye doctor with examine your eyes to make sure that you will be able to wear contact lenses without any issues
• they will check your eyesight to see if you need prescription lenses or not
• they will determine your eye parameters and tell you what BC and DIA are best for your eyes, which is very important. Badly fitted contact lenses can cause discomfort, eye irritation and potentially an eye infection
• they will show you how to put in and take out contacts correctly and safely
• they will teach you how to clean and store them properly
• they will recommend the best lens care solution for your eyes (people with tendency for dry eyes will need a solution with moisturizing properties)

To sum up, make sure to visit an eye care provider before ordering any type of contact lenses.
