Do blue light glasses need a prescription to be worn?

In today’s digital age, where screens are an integral part of daily life, blue light glasses (or blue light blockers) have risen in popularity. They promise reduced eye strain, protection from potential sleep disturbances, and overall better eye health. But do you need a prescription to wear them? Let’s shed light on this frequently asked question.

1. What are Blue Light Glasses?

Blue light blockers are specially designed eyewear that filters out or blocks a portion of the high-energy visible (HEV) blue light emitted from digital screens, LED lights, and even the sun. This filtering is believed to reduce eye strain and other potential adverse effects of prolonged screen exposure.

2. Prescription vs. Non-Prescription

The straightforward answer is, no, you don’t need a prescription to wear blue light glasses. They come in two main varieties:

  • Prescription: For those who already wear corrective lenses and want the added benefit of blue light filtering.
  • Non-Prescription: For individuals without vision problems but still want protection from blue light. These are essentially regular glasses but with blue light filtering capabilities.

3. Who Should Consider Prescription Blue Light Blockers?

If you already wear prescription glasses for reading, distance vision, or any other refractive error, it’s wise to get your blue light glasses with the same prescription. This way, you’ll benefit from both corrected vision and blue light protection.

4. The Benefits of Non-Prescription Blue Light Blockers

Even if you have 20/20 vision, prolonged exposure to screens can cause digital eye strain, characterized by headaches, blurred vision, and dry eyes. Non-prescription blue light glasses can be beneficial in:

  • Reducing glare.
  • Minimizing potential damage from HEV light.
  • Preventing sleep disruptions, especially from evening screen time.

5. Making an Informed Decision

Before purchasing, consider:

  • Your Needs: If you have a refractive error or existing prescription, integrate blue light protection into your corrective lenses.
  • Quality: All blue light blocker are not created equal. Look for reputable brands with clear specifications on the amount of blue light they filter.


Whether or not you need a prescription, blue light glasses can offer valuable protection for most screen users. Consider your personal needs, do your research, and choose glasses that give your eyes the best defense in our digital world.
