Is it dangerous to always use sunglasses? Yes, in a nutshell.
If you wear sunglasses in dim indoor surroundings on a regular basis, anything from your sleep schedule to your eyes’ capacity to adjust to light fluctuations could be jeopardized.
Sure, we should all wear sunglasses more often than we do, particularly when we are outside and need to protect our eyes from dangerous ultraviolet (UV) rays. When you do not need UV protection, though, wearing sunglasses can hurt your eyesight in the long run.
Let us have a look at how sunglasses protect our eyes and why wearing them all the time can lead to vision and sleep problems:
How Do Sunglasses Protect Our Eyes?
When you wear dark-tinted sunglasses, you are exposing your eyes to less light. When the light in the environment is dim, our pupils naturally dilate or expand to let more light into the eye, allowing more light to reach the retina.
This instinctive reflex lets humans adjust to changing light levels, allowing us to see in both near darkness and bright sunlight. Because the autonomic nervous system is in charge of this process, we do not have to think about it.
Wearing sunglasses elicits the same automatic response, especially when you are indoors and your surroundings appear to be extremely dim. Many of the side effects of excessively wearing sunglasses originate from having the pupils dilated for unusually long periods of time.
How Can Wearing Sunglasses Indoors Harm Our Eyes?
Wearing sunglasses indoors will not impair your eyesight, but it will strain your eyes and cause eye fatigue. Headaches, impaired vision, and increased light sensitivity can all result from this, especially true with dollar-store sunglasses, which may cause you to endure more eye strain due to their low optical quality.
Additionally, if you wear sunglasses too often, your pupils will get dilated for an extended period; this reduces the amount of light exposed to your entire visual system and can impair your retina’s ability to adjust to brighter light conditions fast.
Wearing sunglasses indoors may provide relief for people with photophobia or excessive sensitivity to light, but eye experts advise against it. Wearing dark-lens sunglasses indoors can make photophobia worse in the long run. It may also lead to the development of light sensitivity in persons who have never had it before.
Can Wearing Sunglasses All the Time Disrupt Your Sleep Patterns?
Absolutely. Hormones generated every day in response to changing environmental factors control our sleep and waking cycles. Our retinas’ light-sensitive photoreceptors play a critical part in regulating our circadian rhythms (physical, mental, and behavioral changes that follow a daily cycle).
Everything from metabolism to sleep is influenced by light, which is the primary regulation of our day-night cycle. To assist in controlling the quality of our sleep, we need to be exposed to bright daytime light, especially in the morning.
Wearing sunglasses all day filters that morning light and can interfere with your body’s natural sleep routines. It is a little like always being in a semi-darkened room. If you want to protect your ability to sleep deeply, do not put those shades on until after 9 or 10 a.m.
