Blue light glasses are mainly for easing eye strain from screens and might help with astigmatism discomfort. But they can’t fix the uneven shape of the eye that causes astigmatism.

We’ll discuss these topics in this blog:

What is astigmatism?

Astigmatism is when your eyes don’t bend light properly, making things blurry or distorted. It often happens with other vision problems, like nearsightedness or farsightedness.

If you have astigmatism, you might notice:

  • Blurry vision
  • Headaches
  • Eye discomfort
  • Squinting to see clearly
  • Eye strain

Regular reading glasses won’t help. You need special glasses or contact lenses made by a doctor.

To get the right glasses, the eye doctor will:

  • Check how well you can see
  • Use a special tool to see the shape of your eye’s surface
  • Write a prescription that shows how much extra help your eyes need
  • They might also talk about surgery to fix it, like LASIK.

What Lenses Are Used for Astigmatism? 

The strength of the lenses and the type of lenses are both really important for fixing astigmatism.

Astigmatism changes the shape of the front of your eye, making it more like a football or an egg than a baseball. Because of this, light doesn’t go through your eye in the right way. That’s why it’s helpful to have special glasses with the right strength to fix it.

The prescription for these glasses will have a part called “Cylinder” (CYL). It shows how much extra strength is needed to fix the astigmatism. This is a key part of the glasses prescription.

But it’s not just about how strong the lenses are. The type of lens also matters a lot.

Does Blue Light glasses help with astigmatism?

Blue light glasses don’t fix astigmatism. They’re made to help your eyes feel better when you look at screens a lot. But if you have astigmatism, you still need special glasses or contacts from the eye doctor to see clearly. Blue light glasses might make your eyes feel less tired, but they won’t fix astigmatism by themselves.

Do you need Blue Light Lenses?

Blue light glasses stop blue light from affecting your body clock. This matters if you’re on screens a lot or in rooms with LED lights.

But it’s important to think about how much blue light you get, even if you wear these glasses. A simple way to help is to use screens less at night and take breaks during the day.

Also, using softer lights that you can adjust can make your surroundings feel more like natural light. This can help you sleep better.

The Benefits Of Blue Light Lenses

Blue light glasses are getting more popular as we use screens more. They might not prevent some eye problems, but they do help us sleep better.


Blue light glasses can tell our bodies it’s time to relax and get ready for sleep. This can help us feel more awake and get more done during the day. Using these glasses can be a good way to stay energized and balanced.

Managing Depression & Anxiety

When we don’t sleep well, it can make us feel more likely to be depressed or anxious. Blue light glasses can help fix our sleep cycle and indirectly support our mental health. They help us sleep better and feel better overall.

Blue light glasses can also help us see better outside, like when we’re in the sun. They reduce glare and help us focus on what we’re doing or enjoy the view around us.

Remember to talk to an eye doctor for personalized advice about your eyes.


Q1. Does blue light affect astigmatism?

A1. Astigmatism was also found to be reduced during development by blue light, according to the study. In animal experiments, the growth of the eye axis and the glass cavity in guinea pigs was inhibited by monochromatic short-wave blue light, resulting in hyperopia.

Q2. What type of glasses are best for astigmatism?

A2. Typically, toric lenses are recommended for people with moderate to high astigmatism due to the different degrees of curvature over different parts of the lens.

Q3. Can glasses help with astigmatism?

A3. Correctors of astigmatism commonly use lenses or contact lenses. These lenses have a unique design that allows light to focus on the retina, despite the irregular shape of the eye. The cylindrical lens on astigmatism glasses corrects the uneven curvature of the cornea or lens.

Q4. Do blue light glasses help with bad eyesight?

A4. In the short term, blue-light-filtering spectacles have no advantage over standard clear lenses when it comes to reducing vision fatigue, according to the analysis of the trials. Among the studies, only one examined whether blue-light-filtering glasses had any impact on eyesight.

Q5. How do you fix astigmatism at night?

A5. You will be able to see better at night if you wear toric or gas-permeable lenses, as these lenses are more rigid than other lenses. If you have a moderate form of astigmatism, these lenses will be able to assist you.
