Ever since LASIK gained approval from the U.S. Food and Drug Administration in the 1980s, people have been clamoring for a chance to improve their eyesight almost overnight. Various benefits have contributed to LASIK’s rise in popularity – everything from short recovery times to painless procedures has made LASIK attractive to patients of all ages.

Though LASIK can give you better eyesight than you ever thought possible, it can’t help you see in the dark. For that, you’ll have to turn to one of the most iconic military devices of modern times – night vision goggles.

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.
