Quite a few people live with nearsightedness, farsightedness, and other problems that leave them looking at the world from a significantly blurred perspective. Thankfully, eyeglasses and contact lenses are available to clear up those situations. Still, they’re not always completely effective. Using eyeglasses can be problematic as well due to constantly having to update their prescriptions and replace them.
Correcting One’s Vision for Good
One alternative to standard corrective lenses is laser eye surgery. As noted in my latest blog post, this type of procedure can correct different vision issues, including nearsightedness, farsightedness, and astigmatism. LASIK can provide relief from combinations of these vision issues as well. If you’d like to learn more about these types of procedures, keep reading.
Exploring Vision Issues
Corneas take in light and focus it on the backs of the eyes to produce an image of what the eye sees. That image is then transmitted to the brain to be deciphered. For the billions of people who have refractive issues, the corneas are not shaped quite right to project a clear image of what’s in front of them.
As a result, their vision is blurry. For people with myopia, or nearsightedness, images up close tend to appear clear whereas those that are far away are blurry. Those who suffer from hyperopia, or farsightedness, see far-away images clearly while up-close items appear fuzzy. Astigmatism, on the other hand, causes vision issues due to other irregularities in the cornea or the lens of the eye, according to realtimecampaign.com.
How Does Laser Eye Surgery Work?
LASIK and other refractive procedures are designed to resolve vision issues. They entail using a laser to reshape the cornea. After the procedure, patients are able to see more clearly than they did before, even without the use of corrective lenses in some cases. Other times, patients still require corrective lenses, but their prescriptions aren’t quite as strong as they were before.
Many people ask, “Does Laser Eye Surgery (LASIK) Hurt?” They’re generally relieved to learn that the procedure doesn’t hurt at all. Numbing drops are placed in the eyes before the procedure. Patients may feel a bit of pressure during the procedure but no actual pain.
Professionals like those at SharpeVision also point out that people may experience a slight burning or itching sensation after the procedure. This generally goes away within a few hours. Many patients see immediate improvements in their vision after LASIK, but results take a few hours or days for others.
Taking Advantage of the Available Technology
There was a time when corrective lenses weren’t available. People who couldn’t see clearly simply had to muddle through life the best way they could. When corrective lenses were developed, those with vision problems were able to see the world from an entirely new perspective. From that point on, eyeglasses and contact lenses continued to improve. Today, surgical procedures are available to reduce or eliminate the need for corrective lenses, and an estimated 10 million people have already taken advantage of the latest technology.
