Short answer: you can usually wear non-prescription blue light glasses after LASIK once your surgeon says it's fine to wear glasses again, but they aren't part of LASIK aftercare and won't help your eyes heal. Always follow your surgeon's instructions first. The dryness and light sensitivity many people notice after LASIK come from the surgery itself and from blinking less at screens, not from blue light. Where blue light glasses have a clear use is the evening: an orange or red lens cuts most blue light in the two to three hours before bed, with or without LASIK.
Below: what LASIK changes, why screens can feel harder afterward, and where blue light glasses fit in.
Important: this article is general information, not medical advice. Your surgeon's aftercare instructions come first, including any protective shields, sunglasses, eye drops and limits on screen time. If you have pain, worsening vision or increasing redness after LASIK, contact your surgeon straight away.
What LASIK Changes, and What It Doesn't
LASIK reshapes the cornea, the clear front of the eye, so it focuses light correctly. It's used to correct nearsightedness, farsightedness and astigmatism, so you need glasses or contacts less, or not at all.
It doesn't change:
- How light affects your body clock. Bright, blue-rich light in the evening can still delay the rise of melatonin, the hormone that tells your body it's getting dark.
- How you use screens. Focusing up close for hours and blinking less still leave eyes feeling tired and dry.
- Age-related reading vision. From your 40s, most people find small print harder to read, and LASIK for distance vision doesn't prevent that.
Why Screens Can Feel Harder After LASIK
Dry Eyes
Dry eye is common after LASIK and usually improves over time. Screens make it more noticeable, because we blink much less when we concentrate. Your surgeon will usually recommend lubricating eye drops; use the ones they suggest, as often as they suggest.
Light Sensitivity and Glare
Many people are more sensitive to bright light for a while after LASIK, and some notice glare or halos around lights at night. How long this lasts varies from person to person, so ask your surgeon what to expect for you.
None of this is caused by blue light specifically, and blue light glasses aren't a treatment for it.
Do Blue Light Glasses Help After LASIK?
For Screen Comfort
There's no evidence that blue light glasses help after LASIK specifically. More generally, a 2023 Cochrane review found blue light filtering glasses probably make no difference to eye strain in the short term, and the American Academy of Ophthalmology says the light from screens doesn't damage the eyes. Some people simply prefer the look of a screen through a clear or yellow lens; if your surgeon is happy for you to wear glasses, that's a fine reason to.
What helps more with screens after LASIK:
- Blinking fully and often
- Using the eye drops your surgeon recommends
- Taking breaks: every 20 minutes, look at something 20 feet away for 20 seconds
- Turning screen brightness down to match the room
- Following any screen-time limits your surgeon gives you in the first days
In the Evening
This is where blue light glasses have a clearer purpose, for everyone, whether they've had LASIK or not. An orange lens blocks 99% of light across 380–550nm and a red lens 99.7% across 380–580nm, as measured by Micro-Light Optics, cutting most blue light in the two to three hours before bed. See wearing blue light glasses before bed.
Outdoors
Blue light glasses aren't sunglasses. After LASIK, wear the sunglasses or eye protection your surgeon recommends outdoors. For everyday sun protection later on, look for a UV400 lens that's dark enough for bright light. See do blue light glasses block UV rays?
Choosing Blue Light Glasses After LASIK
- Non-prescription: if LASIK corrected your distance vision, choose non-magnifying glasses. See blue light glasses with no magnification.
- Reading glasses: if small print is getting harder, our ReadAid reading glasses combine magnification with a clear lens that blocks 35% of blue light across 400–500nm. Ask your optometrist which strength suits you.
- Daytime screens: clear InvisiAid (35% across 400–500nm, 86% light transmission) keeps colors natural.
- Evening: orange SleepAid or red SleepAidMax.
A Note on Night Driving
If you notice glare or halos at night after LASIK, don't drive after dark until your surgeon says it's safe. No tinted lens improves night vision, and orange and red lenses must never be worn for driving. See our guide to blue light glasses for driving.
Frequently Asked Questions
Can I Wear Blue Light Glasses After LASIK?
Usually yes, once your surgeon says you can wear glasses again. Non-prescription blue light glasses don't change your vision. Ask your surgeon if you're unsure.
Do I Need Computer Glasses After LASIK?
Not usually. If LASIK corrected your vision, you don't need glasses for the computer. If close-up work is getting harder, especially from your 40s, you may need reading glasses: an eye exam will tell you.
How Long Will My Eyes Be Sensitive to Light After LASIK?
It varies from person to person. Your surgeon is the best person to tell you what's normal for you, and when to get in touch if it isn't improving.
Do Blue Light Glasses Help LASIK Recovery?
No. There's no evidence they affect healing. Follow your surgeon's aftercare, including eye drops and any eye protection they recommend.
Conclusion
LASIK corrects how your eyes focus, but it doesn't change how screens or evening light affect you. Blue light glasses won't help you heal, and your surgeon's aftercare comes first. Once you're cleared to wear glasses, a clear lens is fine for daytime screens if you like it, and an orange or red lens cuts most blue light in the evening before bed.
