An Introduction to Contact Lenses
Contact lenses are a contemporary solution for vision correction. With over 168.5 million people in the United States using corrective eye devices, including contact lenses or glasses, their popularity continues to grow. So, what makes contact lenses so favored? This article explores their advantages and answers common questions about these vision aids.
Functions of Contact Lenses
Contact lenses are small, prescription lenses placed directly on the eyes.
They are designed to correct refractive errors and support eye health. They help focus light so images appear sharper.
Worn on the surface of the eye, they rest on the tear film covering the cornea.
Similar to eyeglasses, contact lenses move with eye movements, providing a natural field of view without needing to turn your head.
Features of Contact Lenses
Each contact lens has a designated usage period—daily, weekly, monthly, or yearly—to ensure hygiene and health.
Prescription durations vary based on the eye care professional’s assessment, fitting the individual's needs.
They come in bifocal, multifocal, and monovision styles, ideal for both nearsightedness and farsightedness.
Cosmetic lenses, which can be corrective or purely decorative, are available in colors like red, blue, violet, green, and gray to enhance or change eye appearance.
Who Should Avoid Wearing Contact Lenses?
Individuals with severe allergies, frequent eye infections, living or working in dusty environments, or experiencing dry eyes unsuitable for lens wear should avoid contact lenses.
Young children are generally not advised to wear contacts due to their limited understanding of proper care and the risk of mishandling.
Adults are the recommended users, with children typically opting for glasses until they are capable of managing contact lens hygiene.
