These past few years saw a surge in the production 3D movies, which particularly appeals to moviegoers looking for a more immersive movie experience, since it shows more depth and enhances everything. From “Avatar” to “The Hobbit”, numerous big-budget Hollywood films are now shooting on specialized 3D cameras or converting them to 3D post-production, and people are eager to see the action unfold almost literally before their eyes. Now, you can even view 3D films at home through your Blu-ray player or with a 3D television.
If you’re an avid fan of 3D films, and you don’t mind spending a couple more bucks for a three-dimensional movie experience, you might have experienced a bit of headache now and then while watching one. If that is the case, you might want to visit reliable eye doctors in Indianapolis as soon as possible, especially if your eyesight is beginning to blur. In a study published in the Journal of Vision, the researchers from the University of California-Berkeley found that 3D movies can cause eye strain and fatigue.
In their study, the participants were made to watch a 3D video at varying distances and were made to answer questionnaires on their eye strain, fatigue, and vision clarity. The participants responded that they experienced more eye strain from videos with different vergence distance, or where on the image eyes are fixated. For 3D videos, the vergence distance varies, and can appear to be either deeper than the surface of the screen or in front of it.
Optometrists in Australia, meanwhile, discouraged children from watching 3D films. Not only does it cause them to feel fatigued and nauseous, the process of fusing two images to make a three-dimensional image can be too much for them, particularly for their developing eyes, and might have a long-term effect in their eyesight.
There are other causes of eye-strain, such as staring at your computer for a long time, reading fine print, or straining to see in the dark. Eye strain, the medical term for which is asthenopia, occurs when your eyes begin to grow tired of looking at something, and is usually not at all serious. At times, however, eye-strains are indicative of more serious eye conditions, including myopia, hyperopia, or astigmatism.
Like watching the television for too long or staring at a computer screen for a prolonged period, watching 3D movies also have to be done in moderation, particularly for children. Going to trustworthy Indianapolis eye doctors like those from established practices such as Moody Eyes can help you determine whether there is an underlying problem behind your eye strain.
