Final answer:
Ortho-K lenses are generally considered safe when prescribed and monitored by an eye care professional, though they do carry risks like infections. They are suitable for a wide range of ages if proper hygiene and care instructions are followed.
Step-by-step explanation:
Orthokeratology (Ortho-K) lenses are specially designed contact lenses that temporarily reshape the cornea to reduce or correct myopia (nearsightedness). When considering the safety of Ortho-K lenses, it is important to recognize that they are generally considered safe when prescribed and monitored by an eye care professional. However, like any contact lens wear, there are risks associated, such as the potential for eye infections or corneal scarring if the lenses are not properly cared for or fitted. With proper hygiene, regular check-ups, and adherence to the eye care professional's instructions, the risks can be significantly minimized.
Ortho-K lenses are safe for a wide range of ages, including children and adults, making them a versatile option for correcting vision. They are particularly popular among individuals who wish to be glasses-free during the day and are suitable for various activities, including sports. The effectiveness and safety of Ortho-K have made it a preferred choice for certain individuals seeking a non-surgical approach to vision correction. Nonetheless, it is critical for each patient to undergo a thorough eye examination and consultation to determine if they are a good candidate for Ortho-K lenses.
