What Are the Side Effects of Wearing Sunglasses? 10 Problems They Can Cause

If you’ve ever wondered whether or not sunglasses have any side effects, wonder no more! In this blog post, we’ll explore the potential side effects of wearing sunglasses, from the mundane to the potentially serious. So put on your shades and let’s get started!


Wearing sunglasses can cause headaches due to the strain on the eyes. They cause the pupils to constrict, which can lead to a headache. In addition, if the sunglasses are not fitted properly, they can cause tension headaches.


Eye fatigue

Your eyes have to work harder when they are shaded. The sun’s rays are blocked by the lenses in sunglasses, so your pupils dilate in order to let in more light. This can cause your eyes to become tired and strained. In addition, if you wear prescription sunglasses, the extra weight of the lenses can also contribute to eye fatigue.


Because the lenses block out the light, it is harder for your eyes to adjust to changes in brightness. This can cause you to feel disoriented and can lead to headaches or nausea. If you experience these symptoms, try removing your sunglasses and allowing your eyes to adjust gradually to the change in light.


Sunglasses are often worn to protect the eyes from the harmful effects of ultraviolet (UV) radiation. However, some people experience nausea when wearing them. This may be due to the fact that sunglasses block out all light, including natural light cues that help the brain regulate its internal clock. As a result, wearing sunglasses can disrupt the body’s natural circadian rhythm, which can lead to feelings of nausea.


Dry eyes

While the weather is getting warmer, people are reaching for their sunglasses more and more. However, as Vision Direct reports, there are some potential side effects associated with wearing sunglasses that we should be aware of, including dry eye and changes in our vision.

Increased sensitivity to light

Shades can cause increased sensitivity to light because they block out some of the visible light spectra. This can make it difficult to see in low-light conditions and can cause headaches and eyestrain. If you experience these side effects, try wearing sunglasses that allow more light to pass through, or take them off periodically to give your eyes a break.

Decreased night vision

Wearing sunglasses during the daytime can reduce the amount of light that reaches your eyes, which can lead to decreased night vision. Also, if you wear them for extended periods of time, it can cause headaches and eyestrain.



If you are not used to wearing them, it may take a few days for your eyes to adjust. Additionally, prolonged use of sunglasses can cause headaches.

“Halo” effect around lights

This is because the pupil is dilated when you wear sunglasses, and the light that would normally be focused on the retina is instead focused on the area around the pupil. This can cause glare and make it difficult to see.

Difficulty seeing in low light

The American Optometric Association warns that “sunglasses that are too dark can actually cause accidents by decreasing visibility, and by causing eye fatigue.” They recommend frames like Ray-Ban that allow light to reach the eye in a natural way.


How to find the right pair for your face shape

The right pair of sunglasses can do more than just protect your eyes from the sun — they can also flatter your face and help you to look your very best. To find the perfect pair of shades, first, determine your face shape and then choose a style that complements it.

• Oval: Look for sunglasses with curved frames — they’ll help to elongate your face.
• Round: Try a square or rectangular frames to help give your face more definition.
• Heart: Choose frames that are wider at the bottom to help balance out the proportions of your face.
• Square: Select frames that are soft and round to help soften the angles of your face.

How to find the right model for your lifestyle

Sunglasses are more than just a fashion accessory — they’re an important tool for protecting your eyes from harmful UV rays. With so many different styles and types on the market, it can be difficult to know which pair is right for you. Here are a few tips to help you find the perfect pair for your lifestyle.

If you’re an active person…

Look for sunglasses that stay put, even when you sweat. Sports models are designed to grip your face, so they won’t fall off when you break a sweat. They also tend to have larger lenses that give you a wider field of view.

If you live in a sunny climate…

Consider models that offer high levels of UV protection. If you’re going to be spending a lot of time outdoors, it’s important to choose a pair of sunglasses that can block harmful UV rays. Look for lenses that are labeled “UV 400,” which means they can block 99-100% of both UVA and UVB rays.

If you wear glasses…

There are plenty of options for people who need prescription sunglasses. You can either purchase prescription sunglass lenses that fit into your favorite frames or look for frames that have built-in prescription lenses.

Once you’ve found the perfect pair for your lifestyle, be sure to take care of them! Store them in a case when they’re not being worn, and clean the lenses with lens cleaner and a soft cloth.



While sunglasses are beneficial in many ways, there are also some potential side effects to consider. They can cause eye fatigue, headaches, and even migraines in some people. In very rare cases, it is possible for sunglasses to damage your eyesight if they are not properly made or fitted. If you experience any of these side effects while wearing sunglasses, be sure to consult with an eye care specialist to determine if they are the right type of eyewear for you.
