Blue block glasses filter the high-energy blue light emitted by digital screens like phones, laptops, tablets, and monitors, helping reduce digital eye strain, headaches, and sleep disruption caused by prolonged screen use.

Shop Blue Block Glasses for Men and Women

Our blue block glasses collection with frames comes in a range of shapes—rectangle, round, aviator, cat-eye, square, and more. The styles sit alongside our wider eyeglasses range, so you have plenty of choice rather than a handful of dedicated options.

If you’ve already chosen a frame from the site, you can add blue block lenses to it directly. Go to any frame in our men's eyeglasses or women's eyeglasses collection, select 'Choose Lenses and Buy', and choose blue block as your lens type. 

For those who prefer to shop by lens type first, the frames in this collection have been selected to work well with blue block lenses and come ready for both prescription and non-prescription orders.

Benefits of Blue Light-Blocking Glasses for Digital Eye Strain

Blue light sits at the high-energy end of the visible light spectrum. Unlike UV rays, which the cornea and lens naturally block, blue light passes through to the more sensitive parts of the eye. Blue light-blocking glasses address this in a few practical ways:

  • Reduced eye strain: The visual fatigue that builds up after long hours on a screen—dry eyes, a heavy feeling, difficulty refocusing—is closely linked to blue light exposure. Filtering it out makes sustained screen use more comfortable.
  • Fewer headaches: For people who experience screen-related headaches, blue block lenses can help reduce the frequency, particularly with extended computer or phone use.
  • Better sleep: Blue light in the evening disrupts the body's natural sleep signals. Wearing blue block glasses during evening screen use can make it easier to wind down, without having to put your phone away hours before bed.
  • Suitable with or without a prescription: You do not need vision correction to benefit from blue block lenses. If you do wear prescription glasses, blue block coating can simply be added to your existing prescription.

If you are unsure which lens option is right for you, you can book an eye test at any Optica branch. Our optometrists can assess your eyes and give you personalised advice on the most appropriate lens choice.

Frequently Asked Questions

1. What are blue block glasses?

Blue block glasses are eyewear fitted with lenses that filter high-energy blue light, primarily the kind emitted by digital screens. They are also referred to as blue light glasses, bluelight glasses, computer glasses, or blue light spectacles. The lenses reduce eye strain and visual discomfort during and after screen use, and may also support better sleep when worn in the evening.

2. Do I need a prescription to get blue block glasses?

No. Blue block lenses are available with or without a prescription at Optica. If you do not need vision correction, you can order non-prescription blue block glasses and still get the full benefit of the lens. If you already wear corrective lenses, blue block coating can be added to your prescription.

3. Who are blue block glasses suitable for?

They are suitable for anyone who spends a significant amount of time looking at screens—office workers, students, freelancers, gamers, and people who regularly use a smartphone or tablet in the evenings. Optica offers options for men, women, and children.

4. How do blue light glasses actually work?

The lenses contain a coating that filters out a portion of the blue light spectrum before it reaches your eyes. Depending on the lens, this can range from filtering out a small percentage to blocking the majority of blue light. The result is less visual strain during screen use and, for evening wear, less interference with your sleep cycle.

5. Can I add blue block lenses to any frame?

Yes. At Optica, blue block lenses can be added to any spectacle frame in our collection. You are not limited to the frames listed in this collection. Choose any frame from our men's, women's, or kids' eyeglasses range, go to the product page, select 'Choose Lenses and Buy', and then choose your lens type.

6. How do I order blue block glasses online from Optica?

The process has four steps. First, find a frame you like, either in this collection or anywhere in our eyeglasses range. Second, go to the product page and select 'Choose Lenses and Buy.' Third, select your prescription type. Fourth, add to cart and check out, choosing either home delivery or branch pickup.

7. How long does delivery take?

Optica delivers across Kenya within 1 to 3 days. Free delivery applies on orders above KSh 3,000. If you prefer to collect in person, you can choose any Optica branch at checkout and pick up your glasses there instead.

8. Can I get an eye test before ordering?

Yes. If you are unsure about your prescription or want professional advice before choosing your lenses, you can book an eye test at any Optica branch. Our optometrists will assess your vision and advise on the most suitable lens option for your needs.

9. Are blue block glasses the same as photochromic lenses?

No. Photochromic lenses automatically darken in sunlight and lighten indoors. They are designed primarily for outdoor light transitions. Blue block lenses are designed specifically to filter digital blue light from screens. Both are available at Optica, and some photochromic lenses also include blue light filtering. If you are unsure which suits you best, booking an eye test is a good starting point.

10. Do I need to wear blue block glasses all day?

Not necessarily. They are most useful during screen use, so wearing them while working at a computer, scrolling on your phone, or watching something in the evening will give you the most benefit. That said, blue block glasses are designed for everyday use and are comfortable to wear throughout the day if you prefer.
