Buying contact lenses without a prescription is a risky practice that can lead to serious eye problems. Contact lenses are medical devices that must be fitted by a qualified eye care professional to ensure they are the right size, shape, and power for your eyes. Wearing contact lenses that are not properly fitted can cause corneal abrasions, ulcers, and even blindness.
If you are considering buying contact lenses without a prescription, please reconsider. It is not worth putting your eye health at risk. There are many affordable ways to get contact lenses with a prescription, including online retailers and discount stores.
