Because Astigmatism is Tiring
Visual Health
One of the most common diagnoses against the astignatismo eyestrain. What is astigmatism? Why produce symptoms such as headaches or burning sensation in your eyes? Then the experts tell us that it is astigmatism and tired.
Imagine then what happens. If we have a cornea with a radius of curvature, for example, vertically higher than the horizontal, the letters reach the retina slightly deformed vertically. That is elongated, which is quite tolerable. If your astigmatism, however, has its principal axis or horizontal plane, points will be thickened which is more annoying.
But if your astigmatism is the main plane oblique, points will be deformed and, on the computer, each pixel is perceived to be a slightly oblique extra effort for the interpretation of each letter. Especially if you use any unusual fonts such as italic or shadows.
So that those who work long hours with the computer need some glasses to “offset” these deformations ¬ tions. This will significantly reduce eye strain from this source. Although not make sense for use on an ongoing basis so it is best used to leave them hanging from the monitor.
If they are made with “anti-reflective glass” also avoids microencandilamientos that may appear on the screen. The astigmatism glasses are characterized in the recipes, having scored the axis on which the crystal must be oriented.
DID YOU KNOW?
Soft contact lenses compensated for, by themselves, low-grade astigmatism while the more rigid contact lenses are capable of neutralizing even higher astigmatism. Being in contact with the eye make it virtually disappears.
