The technology of contact lenses has come a long way over the last couple decades. They have had to see some major upgrades to keep up with the technological upgrades of the world around us, particularly the major shift in reliance on digital-based mediums over paper.
Paper is generally easier on the eyes, but today’s world has gone largely digital. Digital devices have their benefits, including the fact that they allow you to read even when light levels around you are low, and the fact that you can help preserve trees and the environment. But staring at digital screens can be bad for your eye health.
So, if you’re already wearing contact lenses, what should you know about the use of those contact lenses when looking at computers, phones or tablets? And do contacts block blue light in Cape Cod? Here’s some information.
Dealing with blue light emitted by digital devices
While electronic devices for reading can be extremely convenient, it is important to note that extended screen time for reading can result in a condition known as digital eye strain. Usually this occurs after you’ve been staring at a screen for two hours or more. One study indicates more than 80 percent of American adults use devices for at least two hours each day, and many times use multiple devices at once, which puts them at risk of eye strain.
This is a result of the blue light emitted by electronic screens. Ongoing exposure to blue light results in the body’s circadian rhythm being disrupted, which in turn makes it harder for you to get a solid night’s sleep. This is the main reason why experts recommend that you not use screens right before going to bed.
Some studies also indicate blue light exposure can be a factor in increased risk of macular degeneration, cataracts and other vision conditions. If these types of conditions go untreated, you could eventually go blind.
While there is still a lot of research being done about the effects of blue light and methods of avoiding these issues, it is important to note that there are some steps you can take to prevent the issue from becoming severely impactful on your life. One of the steps you can take is choosing the proper contact lenses.
Contact lens technology is now capable of protecting your eyes from glare, light and other stressors that are a result of looking at screens. Curvature in the surface of the lens helps to reduce eye strain. Cape Cod residents who wear contacts that have been designed to block or limit exposure to blue light are able to look at screens, and to switch between on- and off-screen, with much greater ease. These contacts generally have features that help your eyes retain moisture, which resolves one of the most common problems associated with looking at screens for long periods of time.
We encourage you to speak to your eye doctor about the types of contacts available that can help you avoid digital eye strain, and to replace your reading glasses with these contacts.
