Facts to Know from Your Eye Doctor in Durham, NC: About Astigmatism

Symptoms

Oftentimes, astigmatism is accompanied by various other vision problems, nearsightedness or farsightedness among them. What separates them though, is that the former is typically exhibited early in life through symptoms like eye strain, headaches, and the need to constantly squint. This problem can lead children to a difficult time at school.

Causes

Since it could show up in childhood, many experts purport that astigmatism just might be hereditary, where children inherit the refractive problems in their parents’ vision. Another known cause is injury or disease that happened to permanently damage the victim’s cornea function. The disease in this case is called keratoconus, since it makes the cornea thinner and more cone-shaped.

Can Cell Phones Damage Your Eyes?

Less than a decade ago, a cell phone that could receive email was already considered smart. But cell phone capability nowadays has gone beyond a simple email send button. The cell phone has become more technologically advanced with its various applications from social media apps to strategic games. It's not surprising then that people's eyeballs are always glued to this gadget. Chances are, the first thing you do in the morning is to check your phone for text messages, tweets or status updates that came in while you were asleep. But with all the time you spend staring at a cell phone, do you ever wonder if it damages your eyes?

Cell phone screens are tiny compared to those of other mobile devices like laptops and tablets. With a small screen size, you're more likely to squint and experience eye strain as you browse through websites and read e-books. In fact, the Israel Institute of Technology conducted a study wherein calf eyes were exposed to heat and microwave radiations similar to those given off by a cell phone. After the exposure, the researchers concluded that the eyes showed early signs of cataracts, saw blurred images and couldn't focus well.

Having a computer that fits in your palm is a giant leap in this technozoic era. However, too much of a good thing can be bad too, especially for your eyes. Mind your cell phone usage and have regular consultations with your eye doctor to protect your vision.
