Contact Lenses

Contact lenses make vision correction more discreet and the field of view more natural, but the risk is also higher when they are not cared for properly.

Types at a Glance

• Soft daily or monthly disposable lenses: comfortable and quick to adapt to, but you must respect the replacement schedule.
• RGP (rigid gas-permeable) lenses: give sharp images and good astigmatism control, but the initial adaptation period is longer.
• OK lenses (orthokeratology lenses): worn at night and removed during the day, they control the progression of myopia by temporarily reshaping the cornea, and they require strict hygiene and follow-up checks.

Selection and Care

• Make sure your hands are clean before putting them in, and replace and care for them as your eye care professional instructs.
• People with dry eyes, allergies, or corneal disease need to be cautious; if you notice redness, pain, or a foreign-body sensation, stop wearing them and see a doctor.
• OK lenses and RGP lenses need regular corneal health checks, so keep to the follow-up schedule.
