Always consult with an eye care professional before using colored contacts to ensure they are safe and suitable for your eyes.

Concave lenses are primarily used to correct myopia, or nearsightedness, a condition where distant objects appear blurry while close objects can be seen clearly. The concave shape of the lenses diverges light rays, allowing them to focus correctly on the retina, thereby improving distance vision. This correction helps individuals with myopia see distant objects more clearly.

Disposable contact lenses can potentially break in the eye, though it is rare. If a lens were to tear or fragment, the pieces could become trapped under the eyelid or on the surface of the eye, which could cause discomfort or irritation. It's important to follow proper care and usage guidelines to minimize this risk. If a lens does break, it's advisable to seek assistance from an eye care professional.

Nike Maxsight contact lenses were discontinued primarily due to limited market demand and competition from other vision correction options.
