Sunglasses have become an essential part of our daily attire, especially during sunny days. They add a touch of style and provide comfort from the glare of the sun. But amidst their popularity, a question often arises: “Are sunglasses bad for you?” This question brings up a lot of curiosity and a bit of confusion. Are we unknowingly harming our eyes when we slip on our favorite shades, or is this concern just a myth? In this blog, we’ll dive into the inner workings of sunglasses, why we wear them, and ultimately reveal the answer behind this age old question. 

 

 

How Do Sunglasses Work?

At first glance, sunglasses might seem like just tinted glass or plastic slapped onto a frame, but they are definitely much more than that. They protect our eyes in multiple ways, each crucial for maintaining ocular health and comfort. 

Coating

One of the key components of sunglasses is their lens coating. These coatings are more than just a fancy add on, they serve several critical functions:

- UV Coating: This is the most essential feature, blocking harmful ultraviolet (UV) rays from the sun. Overexposure to UV radiation can lead to serious eye conditions such as cataracts and macular degeneration.

 

- Polarized Coating: Polarized lenses reduce glare from surfaces like water, snow, and roads. This is especially beneficial for activities like driving, fishing, or skiing, where glare can impair vision and increase the risk of accidents.

- Anti-Reflective Coating: This coating reduces reflections off the back surface of the lenses, cutting down on eye strain and making your vision clearer.

- Mirror Coating: Mirror coatings add a reflective layer to the front of the lenses, not only for a cool look but also to reduce the amount of light entering your eyes, ideal for very bright conditions.

Material

The material of the lens itself is another critical factor in how sunglasses protect your eyes:

- Glass Lenses: Known for their optical clarity and scratch resistance, glass lenses provide sharp vision but can be heavier and more prone to shattering than other materials.

- Plastic Lenses: These are lighter and more impact-resistant, making them a popular choice for active wearers. Polycarbonate is a common type of plastic lens that offers excellent UV protection and durability.

- CR-39 Lenses: These lenses are made from a plastic polymer that offers good optical clarity, UV protection, and scratch resistance, striking a balance between the benefits of glass and plastic.

Why Do We Wear Sunglasses?

While sunglasses have undoubtedly become a fashion staple, their primary purpose extends far beyond aesthetics.  One of the most critical reasons to wear sunglasses is to shield your eyes from UV radiation. Prolonged exposure to UV rays can cause a host of eye problems, including:

- Photokeratitis: Essentially a sunburn for your eyes, it can cause pain, redness, and temporary vision loss.

  

- Cataracts: A condition where the lens of the eye becomes cloudy, leading to blurred vision. UV exposure is a significant risk factor.

  

- Macular Degeneration: UV rays can damage the macula, the part of your eye responsible for central vision, leading to age related vision loss.

Sunglasses also protect your eyes from physical harm. Whether it’s sand at the beach, dust in the air, or debris from sports and outdoor activities, a good pair of sunglasses acts as a barrier against potential irritants and injuries. Even when you aren’t spending time outdoors, bright sunlight can cause glare, making it hard to see and potentially causing danger in activities like driving. Polarized lenses are particularly effective at reducing glare and improving visual comfort. They can also prevent eye strain and fatigue caused by squinting in bright light. Finally, the skin around your eyes is delicate and more susceptible to UV damage, which can lead to wrinkles and even skin cancer. Sunglasses with larger frames or wraparound styles can help protect this sensitive area from the sun's harmful rays.

Are Sunglasses Really Bad for You?

So, are sunglasses bad for you? The short answer is no, but let’s dive deeper into some common misconceptions and clarify a few points.

The Prescription Misstep

One of the few scenarios where sunglasses might cause issues is if you’re wearing prescription lenses that you don’t need or that don’t match your prescription. Wearing the wrong prescription can lead to headaches, blurred vision, or even eye fatigue. If you need prescription sunglasses, make sure you have your eyes checked regularly to ensure your prescription is up to date, and that your sunglasses are coming from a reliable source.

The Perils of Cheap Sunglasses

Another potential issue arises with low quality sunglasses. Not all sunglasses are created equal. Cheap sunglasses often fail to provide adequate UV protection, which can be more harmful than not wearing sunglasses at all. Tinted lenses without proper UV protection can dilate your pupils, allowing more UV rays to enter your eyes, increasing the risk of damage. Plus, low quality lenses can cause visual distortions, leading to headaches, eye strain, and even accidents. Investing in a good pair of sunglasses from a reputable brand ensures that you get the protection and quality you need for your eye health.

 

For most people, sunglasses are highly beneficial. They protect your eyes from UV radiation, reduce glare, and provide comfort in bright conditions. As long as you’re choosing the right sunglasses and using them appropriately, there’s no reason to fear that they might be harmful. 

Summary:

• Sunglasses have different features based on their lens coating and material.

• Sunglasses can protect your eyes from many UV related illnesses.

• Sunglasses also act as a shield for your eyes.

• No, sunglasses are not bad for you as long as you’re wearing a quality pair.
