A superior epithelial arcuate lesion is a curved area of surface disruption that appears under the upper eyelid. It is associated with mechanical interaction from certain lens edges or dry surface conditions. People may feel scratchiness or notice light sensitivity. Smoother edges and better wetting usually resolve the issue.

Poor tear film can add friction that completes the pattern. Adjusting design and care reduces the rubbing pathway.
Superior arcuate staining reflects interaction between eyelid motion and lens geometry. The repetitive movement concentrates stress along the upper corneal arc. Analysis under slit lamp illumination highlights the exact area of contact. Identifying the mechanical relationship aids in refining lens edge design and tear balance.
Schedule an eye exam if you experience eye discomfort, redness, or irritation while wearing contact lenses. A superior epithelial arcuate lesion can develop from mechanical irritation, dryness, or lens fit issues. An eye doctor can adjust your lenses and provide treatment to promote healing and prevent recurrence.
Regular eye exams are one of the best ways to detect and manage eye diseases early. Many eye conditions develop gradually and may not show noticeable symptoms until they start affecting vision. Visiting an eye doctor routinely helps protect your eyesight and maintain good eye health over time.
Clinicians use fluorescein dye and slit lamp magnification to reveal the arcuate stain. The shape and location point to mechanical stress rather than infection. Symptoms improve quickly when the offending factor is removed. Follow up confirms resolution and comfort.
Switching to a softer edge profile, improving surface wetting, and moderating wear time help. Replacing older lenses reduces micro-roughness that increases friction. Lubrication and screen breaks support a stable tear layer. A few tweaks calm the superior zone.
Continued rubbing can enlarge the area and prolong recovery. Early action protects the optical zone and comfort. Small changes now prevent bigger disruptions later. Listening to mild signs keeps wear predictable.
Is SEAL an infection? No, it is a mechanical pattern.
Do I have to stop wearing lenses? Temporary reduction helps while changes are made.
Will it scar? The surface usually heals smoothly.
