Contact lenses offer a popular alternative to eyeglasses, providing vision correction without frames. While the idea of placing a lens directly onto the eye might seem daunting initially, mastering the proper insertion technique is a skill quickly learned with practice. A successful application not only ensures clear vision but also significantly contributes to long-term eye health and comfort. Following a standardized, hygienic procedure is the foundation for a positive contact lens experience.
Essential Preparation Steps
The process of inserting a contact lens must always begin with meticulous hand hygiene to prevent the transfer of microorganisms to the eye’s surface. Hands should be washed thoroughly with a mild, non-cosmetic soap that is free of oils, perfumes, or lotions, as these residues can contaminate the lens and cause irritation. After washing, hands must be dried completely using a clean, lint-free towel, preventing water droplets or towel fibers from adhering to the lens.
Once clean, visually inspect the lens itself before attempting insertion. The lens should be removed from its storage case using only the fingertip, avoiding fingernails which could tear the delicate material. For reusable lenses, a quick rinse with fresh multipurpose contact lens solution is advised to remove any lingering debris or storage solution. This preparation ensures the lens is clean and ready for the final step of checking its orientation.
Mastering the Insertion Technique
Proper lens orientation is the first step in the insertion technique, ensuring the lens fits comfortably on the corneal surface. A correctly oriented lens should form a perfect, shallow bowl shape with the edges curving smoothly upward.
If the lens is inside out, the edges will flare outward, resembling a soup bowl with a distinct lip. A common method to check orientation is the “taco test,” where the lens is gently folded between the thumb and forefinger; a correct lens will fold into a taco shape, while an inverted one will flatten out or bend outward.
With the lens correctly positioned on the pad of the index or middle finger of the dominant hand, the insertion process can begin. The non-dominant hand must be used to hold the upper eyelid securely at the lash line, preventing involuntary blinking during the application. Simultaneously, the middle or ring finger of the dominant hand, or the thumb of the non-dominant hand, pulls the lower eyelid down to create a wide opening. This action is important because it prevents the lens from simply sticking to the wet eyelid margins rather than the eye’s surface.
The wearer should look straight ahead or slightly upward as the lens is slowly and gently brought toward the eye. Looking upward helps to avoid the natural impulse to blink as the finger approaches the central part of the eye. Once the lens makes contact with the eye, the wearer should hold it in place for a brief moment to allow the lens to adhere to the tear film. Releasing the lower lid first, followed by the upper lid, allows the eye to close slowly. A few gentle blinks or a slow roll of the eye helps to center the lens correctly on the cornea, completing the insertion.
Addressing Common Insertion Difficulties
Experiencing discomfort immediately after insertion often indicates a problem that requires prompt attention. The most frequent issue is the lens being inside out, which causes persistent irritation and an improper fit. If discomfort occurs, the lens should be immediately removed, checked for correct orientation, rinsed with solution, and reinserted. Another common cause of discomfort is the presence of debris, such as dust or makeup, trapped beneath the lens.
If the lens feels gritty, it must be taken out and thoroughly cleaned by gently rubbing it with fresh contact lens solution to dislodge any foreign particles.
Sometimes, the lens may move off-center, particularly if the eye is dry or the application was rushed. If the lens is stuck under the eyelid, applying rewetting drops can help lubricate the eye, allowing the lens to be gently massaged back toward the center of the eye while the eyelid is closed. Patience and a calm approach are beneficial, as rushing can lead to increased anxiety and difficulty during the process.
