What Is Blue Light And Do You Need To Block It
Imagine light passing through a prism, which fans it out into the colors of the rainbow. Each color you see is part of the visible light spectrum, which is defined by wavelengths. Shorter wavelengths generally become more harmful as they decrease, which is why many people want to block too much blue and violet light from reaching their eyes. However, its not a good idea to banish blue light completely. Its found in every light source, including sunlight, and is known to boost your attention and mood. Long-term effects on eye health are unclear, but some studies have shown that rat retina cells die when exposed to extreme levels of blue light.
Blue light plays a major part in controlling your sleep cycle. Too much of iteven everyday levels, if you spend a lot of time in front of a screenhas proven problematic. Daylight, which contains blue light, helps tell your internal clock when its time to start the day or hit the hay. Stare at a blue-light-emitting device for too long at night, and your body might think its still daytime. Blue light, especially, has been found to suppress melatonin for about twice as long as green light. That could mean the difference between falling asleep in 30 minutes and one hour. During the day, such exposure to blue light can help keep you alert, but in the evening hours it can be potentially problematic .
If I Don’t Have Symptoms Of Computer Vision Syndrome Do I Still Need Computer Eyewear
Maybe. According to a study at the University of Alabama at Birmingham School of Optometry, even computer users who are not experiencing computer vision syndrome symptoms might benefit from computer glasses.
The study found that computer workers with no visual complaints often experience reduced productivity and accuracy at the computer. So even if you don’t notice eye strain or other symptoms of Computer Vision Syndrome, it’s a good idea to get an eye exam from a computer vision specialist if you spend a good amount of time each day in front of a computer.

Give Your Peepers A Break
If you have a job that requires closeup reading and computer tasks, your eyes can be going full strength for eight hours or more. Even at home, you can put undue pressure on your peepers when surfing the internet, watching TV, reading, or playing video games. When do your eyes get a break?
Just like every other part of your body, your eyes need a little rest between tasks. Consider using a timer as a reminder. Set your timer to sound every 20 minutes. The recommended 20-20-20 rule means rest every 20 minutes and focuses on something at least 20 feet away for 20 seconds.
Top Tips For Reducing Eye Strain

These attractive but understated designs feature everything from classic plastic Wayfarer-style glasses to metal round and aviator-style frames, all of which feature clear lenses that filter out harsh blue light.

Daytime Or Nighttime Use
Different blue light blocking lenses are recommended for use at different times of the day. Artificial blue light may contribute to digital eye strain and affect your sleep cycle, explains Dr. Hernandez. Since your body still needs to be exposed to blue light during the day time hours to preserve your circadian rhythm, clear or yellow lenses are better for daytime use, says Dr. Hernandez.
If youre struggling with insomnia or using your laptop or smartphone late into the evening hours, on the other hand, you may want to choose darker lenses. Red lenses actually block 100% of blue light along with nearly all green and violet light, which means they block all varieties of light that may be disruptive to your sleep cycle and may help you fall asleep faster if you wear them a few hours before bedtime.

Computer Reading Glasses Used With Contact Lenses
There are many contact lens wearers who can get by without bifocals for close up work but find that the lack of eye lubrication while viewing a monitor for long periods causes problems. Establishing a routine of looking away from the screen and blinking can help with this problem. If eyestrain from monitor viewing is not just caused by a lack of tearing then these glasses might just help. It would be worth checking with your optometrist about the use of a .25 add to your prescription for viewing a monitor at 23 or whatever the distance is to your own monitor. Perhaps these computer eyeglasses could provide some benefits here as well.

What Kinds Of Lenses Are Prescribed For Computer Glasses
The best type of lenses for computer glasses usually depends on your age. If you are in your 40s or older, it’s likely you have some degree of presbyopia. If so, multifocal lenses will usually be your best choice because they provide better depth of focus than single vision lenses. This will let you see your computer screen clearly and also see objects that are closer and farther away than your screen.
Single vision lenses also are a good solution for computer glasses, though your depth of focus will be more limited with these lenses if you are presbyopic. Your eye doctor will help you decide whether multifocal or single vision lenses are the best solution for your work environment and your visual needs.
What To Know Before You Buy Computer Or Gaming Glasses
From work to pleasure and hobbies, digital screens dominate in these areas of our lives.
With time spent at work claiming the majority of our hours, our eyes arrive home tired, irritated and dry.
Depending on the severity of your digital eye strain symptoms, you may even experience headaches, shoulder and neck stiffness, and a number of other uncomfortable side effects.
For individuals who are into gaming, perhaps all you want to do after work or on the weekends is unwind by playing your favorite game. Unfortunately, your eight plus hours a day in front of a computer screen are about to be compounded by additional hours in front of a TV, computer, or other digital gaming screen.
When digital eye strain is causing you discomfort and hurting your vision, its time to do something about it.

Give Your Eyes A Massage
Your eyes do a lot of work for you every day, so naturally, they would appreciate a little pampering. The next time they feel a bit strained, consider giving your eyes a massage. Start by rubbing your hands briskly together to produce a little heat.

Computer Eyeglasses With +25d To +075d Lenses

Aside from poor lighting, dry air, dust and other environmental effects the fact that your eyes just do not like focusing at the distance where the computer monitor is normally located.

When Do You Need Reading Glasses
Just about anyone in their 40s and beyond will, at some point, need reading glasses , Wang says.
Reading glasses help compensate for diminished vision related to presbyopia, the normal age-related loss of the ability to focus on up-close objects, such as words in a book or a text message on a smartphone.
Dr. Michelle Andreoli, an Illinois ophthalmologist and clinical spokesperson for the American Academy of Ophthalmology, says you typically realize the need for reading glasses if you encounter trouble reading small print when youre tired and when lighting in the room is dim, or if you find that its easier to read something when you pull it a little farther away from your face.
Seeing Halos Around Lights
As eyes age, the ability to focus light into the retina can become scattered causing blurred focus or fuzzy vision. This fuzzy vision causes a halo effect, especially when looking at headlights or lightbulbs.
Reading glasses can help correct this issue, however, it could be a sign of a more serious eye condition, such as cataracts therefore it is important to speak to an eye doctor near you.

Computer Glasses Vs Reading Glasses: Which Do You Need
Glasses are glasses, right? Not always.
When it comes to computer glasses vs reading glasses, they are very similar. In fact, some people use reading glasses as computer glasses. The primary difference comes down to how far away the object is from your eyes.
The other difference is that computer glasses often come with a tint or a special coating that helps filter irritating light that comes from computer screens.
Lets quickly summarize the different types of glasses you might wear for using a computer, reading, and regular activities.
- Computer glasses: Use for lit digital screens, an average of 24 inches from your eyes
- Reading glasses: Use for reading printed books or documents, held an average of 15 inches from your eyes
- Regular glasses: Use for general vision correction in single vision or bifocal / progressive based on prescription
- FL-41 glasses: Use for protection against harmful light, or to reduce light sensitivity or migraine
A note about FL-41 glasses. While many people wouldnt know these under the name of computer glasses, the special tint they are coated with helps to filter out specific types of light. This includes the light from lit digital screens. At Axon Optics, we make an advanced version of FL-41 glasses that have been shown to reduce the uncomfortable symptoms of people who are sensitive to bright light or migraine.
