Though modern medical science has managed to produce several noteworthy breakthroughs, such as custom LASIK procedures that can give patients better vision than they ever imagined, there are still a number of things that doctors don’t understand about the human body. For example, scientists still can’t say for certain why humans need to sleep every night.

People with allergies know that when the seasons change, they’re at risk for a few bad days. Sometimes, allergies affect your eyes, too. To maintain your vision and remain a good candidate for a LASIK procedure, you might want to brush up on the science behind allergies and the best way to avoid them.

You finally got the LASIK surgery you’ve always wanted—so, what happens now? After LASIK, your vision immediately improves. The whole recovery process is quick as well. If you work at a job where the risk of eye injury is low, you can probably return to work the next day. You can even fly in an airplane within a day—just make sure to keep your eyes lubricated to protect them from the dry air of the plane.

Technology is supposed to make life easier, and for the most part it does. However, not every form of cutting-edge technology can be as effective, and while it seems that everyone and their mother has a smartphone or tablet these days, the jury is still out on whether these devices are bad for your eyes. 

Even though your eyesight is probably your most important sense in everyday life, there’s a startling amount of misinformation surrounding what makes good vision. Some believe that it’s all genetic and your actions don’t impact your eyesight, while others proclaim that shoveling down carrots before, during and after meals gives them night vision like a cat.
