Difference between Polarised and Non Polarised Sunglasses
Sunglasses are a popular accessory during the sunny season, offering protection against harmful UV rays and reducing glare. However, not all sunglasses are created equal. The primary difference between polarised and non-polarised sunglasses lies in their ability to block out light and reduce glare. In this article, we will explore the differences between these two types of sunglasses, helping you make an informed decision when purchasing your next pair.
Polarised Sunglasses
Polarised sunglasses feature a special lens that contains a polarising filter. This filter is designed to block out horizontal light waves, which are the primary source of glare. The vertical light waves pass through the lens, allowing for clear vision without the blinding effect of glare. This makes polarised sunglasses ideal for outdoor activities such as fishing, driving, and cycling, where glare can be a significant issue.
One of the key benefits of polarised sunglasses is their ability to enhance contrast and provide a clearer view of the environment. This is particularly useful in situations where glare makes it difficult to see details, such as when reading a map or navigating through a forest. Additionally, polarised sunglasses can help reduce eye strain, as they minimize the need to squint or adjust your gaze to compensate for glare.
Non Polarised Sunglasses
Non-polarised sunglasses, on the other hand, do not contain a polarising filter. While they still offer protection against UV rays, they do not block out glare as effectively as polarised sunglasses. Non-polarised sunglasses are generally more affordable and suitable for everyday use when glare is not a significant concern.
One advantage of non-polarised sunglasses is their versatility. They can be worn in a variety of situations, from casual outings to formal events. Additionally, non-polarised sunglasses are often lighter and more comfortable to wear for extended periods.
Choosing the Right Sunglasses
When choosing between polarised and non-polarised sunglasses, consider the following factors:
1. Activity: If you engage in activities where glare is a significant issue, such as fishing or cycling, polarised sunglasses are the better choice.
2. Comfort: Non-polarised sunglasses are often more comfortable to wear for extended periods, making them a good option for everyday use.
3. Budget: Polarised sunglasses tend to be more expensive than non-polarised sunglasses, so consider your budget when making your decision.
In conclusion, the difference between polarised and non-polarised sunglasses lies in their ability to block out glare. While polarised sunglasses offer enhanced clarity and reduced eye strain, non-polarised sunglasses are more versatile and budget-friendly. By considering your needs and preferences, you can choose the perfect pair of sunglasses to protect your eyes and enhance your vision.
