Q: What is Amblyopia?
A: Sometimes called Lazy eye, it is the underdevelopment of central vision in one or sometimes both eyes; it also prevents both eyes from working together.
Q: What exactly is astigmatism?
A: Astigmatism is usually caused by an irregularly shaped cornea, the front surface of the eye. Instead of being a perfect sphere, like a ball bearing or a marble, it can become a little more like a football, being more curved in one direction than the other. This brings light into focus at more than one point on the retina at the back of the eye, resulting in blurry or distorted vision.
Q: What is blue light and why is it dangerous?
A: Blue light is part of visible light and close to UV on the light spectrum. It is naturally produced by the sun, used in fluorescent light bulbs and emitted by LED screens on computer monitors, tablets, and smartphones. The eyes’ natural filters do not block blue light and chronic exposure can cause age – related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.
