# Should you wear sunglasses after LASIK when exercising?

Yes. During the early post-operative period, wrap-around UV-blocking sunglasses are non-negotiable for any patient exercising outdoors.

## Why the rules change after laser surgery

LASIK (laser-assisted in situ keratomileusis) and SMILE (small incision lenticule extraction) temporarily reduce corneal nerve density and blink reflex sensitivity. The clinical result is a tear film that is less stable, less responsive to environmental stress, and slower to recover from evaporative load¹. Patients who exercise outdoors without eye protection during this window will experience a measurable worsening of dry eye symptoms, often misattributed to the surgery itself, when the true driver is environmental stress.

## The post-operative window

In the first three to six months after laser eye surgery, the ocular surface is still recovering its baseline function. UV exposure during this period also matters: the cornea is healing, and cumulative phototoxic damage to the cornea, lens and retina has lifelong consequences².

## What we recommend at Blue Fin Vision®

Every post-laser patient leaves Blue Fin Vision® with the same instruction: wrap-around UV-blocking sunglasses for outdoor sport throughout recovery, and beyond. This is not a precaution. It is part of the surgical result. The tear film recovery period after laser surgery is the single most predictable cause of post-operative dissatisfaction³, and protective eyewear during exercise is one of the few interventions that materially changes that trajectory.

## When to seek clinical assessment

This page is general guidance for healthy post-LASIK patients. Patients with complications, atypical healing, or persistent dry eye symptoms should be reviewed in clinic, not self-managed.

## Clinical Takeaway

Wrap-around UV-blocking sunglasses are protective equipment for any post-LASIK runner, not an accessory. The cornea you have invested in protecting deserves the same protection during recovery, and beyond.
