The world of contact lenses has revolutionized the way people with refractive errors see the world. Orthokeratology or Ortho-K contact lenses are a specialized type of lenses that reshape the cornea of the eye while you sleep, resulting in clearer vision during waking hours.
Ortho-K lenses are a popular choice for people with mild to moderate myopia, or nearsightedness. Unlike traditional contact lenses that are worn during waking hours, Ortho-K lenses are worn at night while you sleep. The lenses gently reshape the cornea, which is the part of the eye that helps focus light onto the retina, resulting in improved vision.
How Do Ortho-K Lenses Work?
Ortho-K lenses are made of gas-permeable materials that allow oxygen to pass through to the cornea. The lenses are designed to be worn overnight, during sleep. As you sleep, the lenses exert gentle pressure on the cornea, causing it to reshape. The reshaping of the cornea helps adjust the way it bends light entering the eye, resulting in clearer vision.
Benefits of Ortho-K Lenses
One of the main benefits of Ortho-K lenses is that they allow people with myopia to see without the need for corrective lenses during the day. This is particularly useful for people who lead an active lifestyle or work in environments where wearing glasses or traditional contact lenses can be a hindrance, such as in construction or sports.
Another benefit is that Ortho-K lenses can slow down the progression of myopia in children. Studies have shown that children who wear Ortho-K lenses have a slower progression of myopia compared to children who wear traditional glasses or contact lenses.
Factors to Consider Before Choosing Ortho-K Lenses
Before considering Ortho-K lenses, it is important to consult with an eye care professional. Factors such as age, lifestyle, and severity of your refractive error will be taken into consideration before determining if Ortho-K lenses are a suitable option for you.
It is also essential to commit to regular check-ups with your eye care professional while using Ortho-K lenses. This will ensure that any changes in vision or eye health are detected and addressed promptly.
Ortho-K lenses are a viable option for people with mild to moderate myopia who want to reduce their dependence on corrective lenses during the day. While there are several benefits to using Ortho-K lenses, it is essential to consult with an eye care professional before making a decision. With the proper care and regular check-ups, Ortho-K lenses can provide a safe and effective alternative to traditional corrective lenses.
