Sunglasses are more than a fashion accessory. They guard your eyes from the harmful UV rays. Like a sunscreen protects your skin, the right sunglasses do the same for your eyes. However, when it comes to selecting sunglasses, there are two options available. You may opt for UV-protective or polarized sunglasses.
Both these options are good, but serve different purposes. So, to make a choice, you need to understand how each one works. Here, we have explained the functionalities of UV-protective sunglasses and polarized sunglasses as well as the differences between them.
UV-Protective Sunglasses
As it is apparent, these sunglasses guard your eyes from the ultraviolet (UV) rays. UV rays can harm the delicate tissue present in our eyes. Upon prolonged exposure, they can also result in:
- Macular degeneration
- Cataracts
- Cancers around the eyelid
Look for lenses marked UV 400. They offer 99-100% protection against both UVA and UVB rays. It is the highest plausible shield you can expect with a pair of sunglasses. However, when choosing reflective glasses, exercise caution. Not all the reflective glasses assure UV protection. So, read labels before finalizing the purchase.
Contrary to popular belief, you need not wear sunglasses only in the summer. Sometimes, UV rays may reach your eyes even on a cloudy day. So, wear these sunglasses regardless of the weather outside.
Polarized Sunglasses
These work differently. Primarily, they help reduce glare. Light reflects off surfaces like glass or water. It results in a reflective glare that can obstruct the vision. However, the problem can be avoided with polarized sunglasses.
Such glasses work as a filter. They block the sharp horizontal light and allow only vertical light to pass through. Consequently, you see a clearer view.
Typically, such glasses enhance contrast and darken colors. This can reduce eye strain. These are an ideal choice for use during boating and driving. Avoid wearing these glasses when near reflective surfaces.
People who are routinely exposed to glare suffer from:
- tired eyes
- headaches
- squints
Typically, these glasses do not shield the eyes against UV rays. However, many contemporary options combine both UV protection and glare filtering. They ensure your eyes get all-around protection.
Top Differences Polarized vs. UV-Protective Sunglasses
Purpose

- Polarized glasses reduce reflective glare
Benefits
- UV protection glasses help prevent macular degeneration and cancer
- Polarized sunglasses prevent squints and headaches
What’s Best for You?
UV protection should be the first thing that comes to your mind for the long-term health of your eyes. These lenses are indispensable outdoors, consistently and regardless of the time or season. They save you from vision loss and decrease the risk of sun-related eye diseases.
Conversely, if glare is a problem, especially while driving or on water, then you’ve got a big relief with polarized sunglasses. They enhance visibility and significantly reduce discomfort caused by reflective surfaces.
However, the best option would be a pair of sunshades that infuse the benefits of both.
Choosing the Right Pair for You
Style matters, but eye health should be a top priority. Look beyond lens color or frame shape. Sunglasses must offer full UVA and UVB protection.
Consider your activities, as your use of sunglasses might vary depending on them. For sports and active use, opt for durable polycarbonate glasses featuring a contrast tint for enhanced visibility. Amber or green tints are ideal.
Frames can be larger and more curved to provide more coverage and reduce UV rays from reaching the eyes through the sides. Remember, quality is primary. Affordable yet stylish glasses may never offer the optimal level of protection. So, pick quality over style.
Now that you have clarity about the differences between UV protection and polarized sunglasses, make a smart selection based on your requirements.
