Computer Glasses Vs Blue Light Glasses For Digital Eye Strain?

Summary

This video explains the differences between computer glasses, blue light glasses, and gaming glasses, offering insights into their effectiveness for reducing digital eye strain. Computer glasses are designed with specific magnification to focus at a certain distance, while blue light glasses filter harmful blue light from screens. The video also covers the benefits of prescription computer glasses, including customization for astigmatism and prism correction to further reduce eye strain. It emphasizes the importance of finding the right magnification power based on age and personal needs, and suggests consulting an eye doctor for the best results.

Takeaways

• 😀 Computer glasses help reduce digital eye strain, tired eyes, headaches, and blurry vision by providing a set magnification power for a specific focal distance.
• 😀 The focal distance for computer glasses is typically set between 20 and 24 inches (60 cm), the average distance from the screen to your eyes.
• 😀 Computer glasses work similarly to reading glasses, but they are optimized for looking at screens, not reading close-up text.
• 😀 Reading glasses have a focal distance between 12 to 16 inches (40 cm), designed for up-close viewing like reading a book or using a phone.
• 😀 Over time, your eye muscles get tired from focusing, but computer glasses reduce this strain by lowering the effort needed to focus on the screen.
• 😀 Blue light glasses feature a coating or filter that blocks or filters out blue light from screens, potentially helping with sleep cycles but with mixed results for digital eye strain.
• 😀 The yellow or amber tint in blue light glasses may be beneficial for sleep, especially if you're using screens late in the day.
• 😀 Gaming glasses are essentially blue light glasses with mild magnification (about 0.25 to 0.5 diopters), designed to ease eye strain during gaming sessions.
• 😀 Blue light glasses are typically non-prescription, Plano lenses, meaning they have no magnification or correction power but only the blue light filter.
• 😀 To get the best computer glasses for your needs, it's recommended to visit an eye doctor for a personalized prescription that accounts for astigmatism, different eye powers, and even the option of prism lenses for further strain relief.

Q & A

What are computer glasses and how do they work?

Computer glasses are designed to reduce digital eye strain by providing a set magnification power that helps focus at a specific distance, typically around 60 cm, the usual distance from your screen. They work similarly to reading glasses, reducing the strain on eye muscles when focusing on close-up objects for long periods.

How do computer glasses differ from reading glasses?

The main difference between computer glasses and reading glasses lies in their focal point. Computer glasses are usually focused at a distance of 60 cm, suitable for screen use, whereas reading glasses focus at a closer distance, typically around 40 cm for reading books or phones.

Can computer glasses help with eye strain and headaches?

Yes, computer glasses can help alleviate digital eye strain, tired eyes, and headaches. By reducing the amount of effort your eye muscles need to focus, they help prevent fatigue and discomfort from long periods of screen use.

What is blue light and how do blue light glasses work?

Blue light is high-energy visible light emitted by digital screens and fluorescent lights. Blue light glasses have a coating or filter that blocks or reduces blue light exposure. They often have a yellow or amber tint to help with sleep cycles, though their effectiveness for digital eye strain relief is debated.

Are blue light glasses effective for reducing digital eye strain?

The effectiveness of blue light glasses for reducing digital eye strain is mixed. While some users report relief, recent research suggests that they may not significantly alleviate eye strain. However, they can help with improving sleep, particularly if used before bedtime.

What are gaming glasses and how do they differ from blue light glasses?

Gaming glasses are a type of blue light glasses designed specifically for gamers. In addition to blocking blue light, they may have a mild magnification (about a quarter or half diopter) to help reduce strain during extended gaming sessions.

Can I get both magnification and blue light protection in the same pair of glasses?

Yes, you can get both magnification and blue light protection in the same pair of glasses. You can have a prescription for computer glasses with magnification and add a blue light coating to those lenses for additional protection.

Why should I get an eye exam to find the right power for computer glasses?

An eye exam helps determine the correct magnification power and can address any issues like astigmatism or varying prescriptions in each eye. Your eye doctor can also customize the lenses with features like prism lenses to further reduce eye strain.

What are the benefits of prism lenses in computer glasses?

Prism lenses help shift the angle of light entering your eyes, reducing the strain on eye muscles and making it easier to focus on objects at a distance. This can help alleviate eye fatigue during prolonged screen use.

Are over-the-counter computer glasses a good option?

Over-the-counter computer glasses can be a good option for those who don't need prescription lenses. They offer various magnification levels to help with close-up screen viewing. However, they don't address issues like astigmatism or provide customized corrections like prescription glasses can.
