Should I Stay In A Dark Room After LASIK?

No, you don’t need to stay in a dark room after LASIK. 

While light sensitivity is common in the first 24-48 hours after surgery, entirely avoiding light is unnecessary, and proper exposure to normal light conditions may even help your eyes recover more naturally.

However, it’s essential to be mindful of your environment and take precautions to protect your eyes during the recovery process. This blog will guide you through everything you need to know about light exposure after LASIK, helping you to ensure a smooth and comfortable recovery.

What Happens to Your Eyes After LASIK?

LASIK (Laser-Assisted in Situ Keratomileusis) is a highly effective vision correction surgery. It works by reshaping the cornea to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. While the procedure is quick—taking only about 10 to 15 minutes per eye—your eyes undergo a significant transformation, which requires careful post-operative care.

After LASIK, your corneal flap begins to heal as your eyes adjust to their new shape. During this recovery period, there’s a heightened sensitivity to light. This is because the cornea, which acts as a protective barrier, has been temporarily altered, and your eyes are adapting to the changes.

Common Symptoms Post-Surgery

Here’s a list of common symptoms LASIK patients may experience within the first few days post-surgery:

  • Sensitivity to light (photosensitivity)
  • Dry eyes
  • Mild irritation or discomfort
  • Halos or glare around lights, especially at night
  • Slight blurring, which improves over time

While most of these side effects subside within a week, light sensitivity is often most noticeable during the first 1-2 days, prompting many to wonder if they should stay in a dark room.

Should You Avoid All Light Exposure After LASIK?

The short answer is no—you don’t need to completely avoid light exposure after LASIK. Light exposure in moderation is not harmful to the healing process.

However, direct, harsh light—like bright sunlight or strong indoor lighting—should be avoided initially. Strain from overly bright environments can make your eyes feel more uncomfortable and contribute to longer-lasting sensitivity.

Why Light Exposure is Beneficial in Moderation

Although too much light can feel uncomfortable, avoiding light altogether isn’t the answer. Here’s why:

  1. Helps Your Eyes Adapt: Gradual exposure to normal indoor lighting helps your eyes adjust and heal properly.
  2. Prevents Over-Sensitivity: Staying in the dark for too long can exaggerate light sensitivity when re-exposed to brighter conditions.
  3. Promotes a Normal Recovery: Your eyes are designed to function in natural lighting conditions. Giving them this exposure fosters proper adjustment and healing.

Balanced Suggestions for Light Exposure:

  • Use soft, ambient lighting indoors during your first few days.
  • Wear protective sunglasses when outdoors, even on cloudy days, to avoid direct sunlight and UV exposure.
  • Avoid harsh, glaring lights or screens, like phones or computers, during the first day post-surgery.

Practical Post-LASIK Recovery Tips for Your Eyes

While there’s no need to stay in a dark room, the right precautions can help alleviate discomfort and support your recovery. Here’s how to strike a balance:

1. Wear Protective Sunglasses

Post-LASIK patients are usually advised to wear sunglasses to shield their eyes from bright sunlight and harmful UV rays. Choose sunglasses with 100% UVA and UVB protection to prevent irritation and ensure optimal healing.

2. Adjust Indoor Lighting

  • Opt for soft, warm lighting (avoid overhead fluorescent lights that can cause glare).
  • Keep your environment comfortably lit, but avoid overly dim lighting, as your eyes still need mild stimulation for proper adjustment.

3. Follow the 20-20-20 Rule

If you return to digital screens sooner than expected, follow the 20-20-20 rule. Every 20 minutes, look away from your screen and focus on an object 20 feet away for 20 seconds to reduce eye strain.

4. Use Eye Drops Regularly

Dry eyes are common following LASIK, making light sensitivity more uncomfortable. Keep your eyes hydrated with the prescribed artificial tears to relieve dryness and discomfort.

5. Limit Screen Time

Screens emit blue light, which can increase sensitivity. Minimise screen exposure for the first 48 hours after surgery and use devices like phones and laptops sparingly.

6. Rest Your Eyes

Most importantly, ensure you rest well. Keeping your eyes closed periodically throughout the day helps accelerate healing and reduces sensitivity to light.

What Happens If You Stay in a Dark Room for Too Long?

While staying in a dark room may seem like a good idea, doing so for extended periods can actually have more drawbacks than benefits:

  1. Delayed Adjustment: Your eyes won’t adapt to normal light conditions, prolonging your sensitivity when reintroduced to brighter environments.
  2. Strain When Re-Exposed: Sudden exposure to brighter light after being in darkness can feel overwhelming, putting unnecessary strain on your healing eyes.
  3. Missed Opportunity to Heal Gradually: Controlled light exposure helps your cornea reprogram its response to varying light intensities, fostering a healthier adjustment.

Signs You May Need Extra Care

It’s important to follow your surgeon’s post-operative instructions and attend all follow-up appointments. However, if you notice any of the following symptoms, contact your eye doctor immediately:

  • Severe, persistent pain
  • Light sensitivity that worsens over time
  • Sudden vision loss or persistent blurring after the recovery window
  • Signs of infection, such as redness, swelling, or yellow discharge

Your doctor can assess whether these symptoms are part of the normal healing process or require additional treatment.

Takeaways for Post-LASIK Recovery

To recap:

  • You do not need to stay in a dark room after LASIK. Instead, opt for controlled exposure to soft, ambient lighting indoors.
  • Utilise protective sunglasses to prevent direct sunlight and glare from harming your sensitive eyes.
  • Keep your eyes hydrated, rest often, and minimise screen use to reduce strain and improve comfort.
  • Gradual exposure to normal lighting conditions is essential for your healing process and prevents prolonged sensitivity later on.

Recovery is a balance. Following the advice of your doctor and being mindful of your environment can expedite the healing process and contribute to an excellent LASIK outcome.

Final Thoughts

Undergoing LASIK is a life-changing decision, and proper post-surgery care is key to ensuring the best results. While some light sensitivity is normal, staying actively engaged in your recovery—without completely retreating to darkness—will give you the smoothest experience.
