Experiencing some blurry vision is common when first wearing new contact lenses. This initial blurriness is a frequent concern, especially for new wearers or those transitioning to a different type or prescription. It is part of an adaptation period as the eyes and brain adjust to a new way of seeing.
Understanding Initial Blurriness
The visual system needs time to adapt to new optical input. When new contact lenses are introduced, the eyes and brain must learn to process light differently, which can initially result in blurriness. This adjustment period, lasting a few days to two weeks, allows the brain to recalibrate its interpretation of visual signals from the new lens surface.
The interaction between the contact lens and the eye’s natural tear film also contributes to initial visual disturbances. Contact lenses rely on the tear film for hydration and clarity; disruption can cause temporary blurriness. New lenses might alter the tear film’s stability or distribution, leading to fluctuations in vision until the eye establishes a new equilibrium. Dryness, common among new wearers, can exacerbate this, as inadequate moisture can cause lenses to warp or accumulate deposits, impairing vision.
Even a well-fitted contact lens can cause temporary visual changes due to its physical presence. The lens material and curvature might interact with the cornea, leading to a different visual experience than with glasses. For individuals with astigmatism, the eye’s accommodative system may react differently to contacts, potentially causing initial blurriness as the eyes adjust to the new refractive properties.
Tips for Adjusting to New Contacts
Proper insertion and removal techniques aid adjustment to new contact lenses. Always wash and dry hands before handling lenses to prevent debris or oils from transferring. Ensure the lens is not inside-out before insertion, as an incorrectly oriented lens causes discomfort and blurry vision. Looking directly at the lens or into a mirror can aid precise placement.
Regular blinking helps distribute the tear film evenly across the lens surface, maintaining hydration and clarity. New wearers might experience increased blinking or tearing initially as eyes adapt. Staying hydrated and using rewetting drops can alleviate dryness, improving comfort and vision. These drops replenish moisture, reducing blurriness caused by dryness.
Adhering to the prescribed wearing schedule supports adaptation and eye health. New wearers should gradually increase wear time, starting with a few hours daily and slowly extending it as comfort allows. This gradual approach allows eyes to acclimatize without excessive strain. Vision often improves over the initial days as eyes fully adapt.
When to Contact Your Eye Doctor
While some initial blurriness is normal, certain symptoms indicate a need for professional consultation. If blurriness persists beyond the typical adaptation period of a few days to two weeks, or if vision worsens, it could signal an underlying issue. This might indicate an incorrect prescription or an unsuitable lens fit.
Pain, stinging, or foreign body sensation in the eye should prompt immediate lens removal and contact with an eye care professional. Redness that does not subside, or appears alongside other symptoms, can be a sign of inflammation or infection. Excessive tearing or unusual discharge also indicate potential infection or irritation.
Sensitivity to light (photophobia) warrants a doctor’s visit, as it can be an early sign of a corneal issue or infection. A sudden decrease in vision, or a feeling that something is in the eye, should also be evaluated promptly. Ignoring these symptoms can lead to serious complications, including corneal ulcers or lasting vision damage.
