For many people, the final touch to their Halloween costume is a pair of special-effect contact lenses. These contact lenses can be found in a variety of colors and styles to bring your costume to life. From bloodshot style contacts that are popular with zombie enthusiasts to white eye color lenses to create a vampire look, there is something for everyone in our wide selection of Halloween contact lenses cheap.

While these Halloween Eye Contacts may seem like low-consequence body decorations, it is important to remember that contact lenses are medical devices approved by the U.S. Food and Drug Administration (FDA). Those who choose to purchase their Halloween contact lenses without a valid prescription are at risk of developing serious eye problems, including permanent blindness, according to the American Academy of Ophthalmology (AAO).

Eyes on Halloween: Exploring the Best Eye Contacts for Your Look

When you buy your Halloween contact lenses from a reputable business and follow the guidelines for use and care, these lenses can help make your costume more realistic and spooky. However, when they are not worn as prescribed — or if they are stored in dirty solutions, or used for extended periods of time or overnight wear — they can lead to irritation, infection and other complications.

To minimize your risk of eye-related injuries, be sure to purchase only from a business that sells FDA-approved costume contact lenses and has an optometrist on staff to provide a professional eye exam and a prescription. Be sure to store your Halloween contact lenses properly in a fresh solution, and don’t share them with others.
