Blue light blocking lenses can effectively combat the damage caused by blue light (from sunlight, smartphones, or other electronic devices). However, when purchasing blue light glasses, you might have questions such as “What sets blue light glasses apart?” “Are all blue light glasses yellow-tinted?” or “Do blue light glasses distort the colors of objects around me?”
This article will discuss how to distinguish blue light blocking glasses from regular eyewear, and introduce different types of blue light blocking lenses. Additionally, we’ll explore potential changes in vision after using them.
Different Types of Blue Light Lenses
Common Blue Light Lenses
Common blue light blocking lenses typically have a slight yellow or amber tint, which varies among different suppliers. At first glance, these blue light blocking lenses may appear indistinguishable from regular lenses, but upon closer inspection, a subtle yellowish hue can be observed.
This tint helps to effectively filter out 100% harmful blue light and reduce its impact on the eyes. The yellow or amber tint can enhance contrast, reduce glare, and improve nighttime vision. These lenses are suitable for individuals who spend extended periods using electronic devices or working in low-light environments, as they can alleviate eye fatigue and discomfort.
No Base Color(Clear) Blue Light Lenses
Clear blue light blocking lenses, as the name suggests, are completely transparent and appear indistinguishable from regular lenses. However, they are also capable of blocking blue light.
No base blue light lenses offer a more natural appearance and do not alter the color of objects. While they provide blue light protection by effectively filtering out harmful blue light wavelengths and reducing eye strain, they offer slightly less resistance to blue light compared to regular blue light blocking lenses, typically blocking around 80% to 90%. These lenses are particularly suitable for individuals who desire to maintain their original visual perception or avoid color distortion.
High Index Blue Light Lenses
High index blue light lenses are a specially designed type of lens with a higher refractive index. This means they are thinner and lighter than common lenses while still providing excellent optical and protective performance.
There are two types of high refractive index anti-blue light lenses: one type is made from materials that naturally resist blue light, similar to regular anti-blue light lenses, and the other type features a coating that blocks blue light. In the latter, a layer of anti-blue light coating is applied to the outer surface of regular high refractive index lenses, providing the same level of protection against blue light as the material itself.
The high refractive index allows the lenses to bend light more efficiently, reducing distortion and deformation of the eyes. This means you can enjoy a clearer, more natural visual experience with a wider field of view, whether indoors or outdoors.
Do Blue Light Lenses Look Different?
Whether anti blue light lenses appear different largely depends on the suppliers. Our blue light lenses are crafted from optical-grade CR39, ensuring they are as lightweight and slim as regular prescription lenses. They also feature anti-glare coatings and scratch resistance. Note: Glare refers to the reflection of other light sources on the lenses. If you’ve worn glasses before, you know how annoying glare can be, especially when driving at night with headlights shining directly into your eyes, causing you to squint or adjust your head angle to see objects clearly. Our lenses can also undergo special hydrophobic surface treatment, making them water-resistant. This prevents water droplets from forming and keeps the lenses clean.
Do Blue Light Lenses Change Screen Color?
Blue light lenses are designed to filter out blue light emitted from screens, but they typically do not alter the color of the screen itself. Instead, they work by reducing the amount of blue light that reaches your eyes while still allowing other colors to pass through naturally. As a result, you may notice a slight yellow or amber tint on the lenses themselves, but the color of the screen should remain unchanged. The purpose of blue light lenses is to alleviate eye strain and discomfort caused by prolonged exposure to blue light, particularly from digital devices, without affecting the visual appearance of the screen content.
Do All Blue Light lenses Have a Blue Coating?
Yes, our blue light lenses can have a blue coating. Typically, anti-blue light lenses use a green coating, but if customers prefer, a blue coating is also available. Both coatings provide the same level of blue light protection. The blue coating is considered more aesthetically pleasing compared to the green coating. Nowadays, more and more customers are choosing the blue coating.
How To Choose The Right Blue Light Lenses?
Firstly, consider your prescription. If your prescription is high, over +-4.50, you may consider high refractive index blue light lenses. Otherwise, you can consider CR39 blue light lenses or clear blue light lenses. The main difference between these two is their tint. If you prefer completely clear lenses, clear blue light lenses are the better choice.
In conclusion, whether anti-blue light lenses appear different largely depends on the specific type of lens and its coating. No base color(clear) blue light lenses, for example, maintain the natural appearance of regular lenses while providing effective blue light protection. On the other hand, blue light lenses blue coating may alter the color perception slightly but are preferred by many for their aesthetic appeal. Ultimately, the choice between clear or tinted blue light lenses is a personal one, based on individual preferences for appearance and color distortion. Regardless of the choice, the primary goal of these lenses is to reduce eye strain and protect the eyes from the harmful effects of blue light emitted by digital screens.
