Removing contact lenses safely and easily requires a gentle, deliberate approach to protect the delicate surface of the eye. Proper technique helps avoid corneal abrasions, which are small scratches on the eye’s surface that cause pain and discomfort. Following the correct preparation steps and using the appropriate method for your specific lens type ensures the removal process is simple and comfortable.
Essential Pre-Removal Preparation
Before touching your eyes or the lenses, thorough handwashing is the mandatory first step to prevent transferring bacteria that could cause infection. Wash your hands for at least twenty seconds using mild, non-lanolin-containing soap. Avoid soaps with lotions or heavy scents, as they can leave a residue that may transfer to the lens and irritate the eye. Dry your hands completely with a clean, lint-free towel or paper towel, since microbes that cause eye infections can be found in water.
Ensure the contact lens is moist and moves freely on the eye before removal. If the eye feels dry, the lens may adhere to the cornea, making removal difficult and potentially causing injury. Applying a few drops of lubricating eye drops or sterile saline solution, compatible with contact lenses, can rehydrate the lens. Blink several times after applying the drops to distribute the moisture evenly, allowing the lens to soften before attempting removal.
Step-by-Step Soft Lens Removal Techniques
Soft contact lenses are the most common type and are removed using one of two primary methods. The principle for both techniques is to move the soft lens off the cornea and onto the white of the eye (sclera) before grasping it. This minimizes the risk of a corneal scratch, which can result from directly pinching the lens while it is centered.
Pinch/Fold Method
This method is performed after sliding the lens down. Begin by looking up and using your non-dominant hand to hold your upper eyelid open while pulling your lower lid down. With the index finger of your dominant hand, gently slide the lens down to the lower part of the sclera. Once the lens is on the white of the eye, use the pads of your dominant index finger and thumb to lightly pinch the lens, causing it to fold slightly and lift away.
Slide/Drag Method
The Slide/Drag Method uses a single finger to initiate the lens’s movement. Use your non-dominant hand to widen your eye opening by holding the upper and lower lids. With the dry pad of your dominant index finger, touch the bottom edge of the soft lens and slowly slide it downward. Continue sliding until it crinkles slightly at the lower eyelid. Once the lens is resting on the white part of the eye, gently pinch it between your thumb and index finger to complete the removal.
Addressing Common Removal Difficulties
A stuck lens is often caused by the lens drying out on the eye’s surface, particularly after napping. The proper action is to rehydrate the lens to make it pliable and movable again, rather than attempting to force its removal. Apply several drops of a sterile lubricating solution or saline directly to the eye. Close your eyelid for a minute or two to allow the lens to fully absorb the moisture.
If the lens remains centered and stuck, gently massage your closed upper eyelid in a circular motion to help break the suction and encourage movement. If the lens has shifted and feels stuck underneath the eyelid, you can often coax it back to the center by moving your eye in the opposite direction. For instance, if you suspect the lens is under your upper lid, look down while gently massaging the lid.
Locating a shifted lens is easier by looking in a mirror and gently manipulating the eyelid to bring the lens into view. Avoid rubbing your eyes vigorously, as this can cause the lens to move further out of place or scratch the cornea with the lens edge. If a rehydrated lens still cannot be removed after several gentle attempts, contact your eye care professional immediately.
Specialized Methods for Hard and RGP Lenses
Rigid Gas Permeable (RGP) and hard lenses are made of a firmer material than soft lenses. Their removal requires a different mechanical action to break the seal holding them to the eye. Unlike soft lenses, do not attempt to pinch or fold an RGP lens with your fingers, as its rigid edge could scratch the eye.
Controlled Blink or Lever Method
This effective technique uses the eyelids to dislodge the lens. Position one finger at the outer corner of your eye, pulling the skin tautly toward your ear while keeping your eyes wide open. A firm blink while maintaining this tension will cause the lens to pop out onto your hand or a clean surface beneath you.
Suction Cup (DMV) Method
An alternative method is the use of a small, specialized suction cup, often called a DMV. After moistening the tip of the suction cup with saline solution, look straight ahead and gently press the concave end directly onto the center of the RGP lens. Once the cup adheres to the lens, pull the lens straight away from the eye in a smooth motion.
