Undergoing LASIK in Durham, NC Allows You to Live a Lens-Free Life

“If you want to experience a lens-free life, all you have to do is visit an ophthalmologist that offers LASIK in Durham NC. Make sure that the doctor is board-certified with enough credentials so you can freely discuss your options.

One important benefit that you can also get from the surgery is the cost involved. There’s no question that you can spend much on contacts, solutions or glasses. On the other hand, undergoing a one-time professional LASIK surgery in Durham NC will eliminate the need to replenish optical supplies that can cost you a thousand dollars annually. Even if the procedure is a major financial investment, it can save you more money in the long run.”


Your Durham, NC Eye Doctor Can Prescribe the Perfect Glasses for You

“Another black mark against glasses purchased online is that, according to the journal Optometry, almost half of them don’t meet impact testing standards. This is an important requirement since the Food and Drug Administration considers all prescription glasses as medical devices. If the lenses shatter or crack easily, they can cause serious damage to your eyes.

Since most glasses have to be replaced every two or three years, it’s understandable why people are looking for cheaper ways to buy them. However, protecting and prolonging your eyesight is a worthy investment. If you’re thinking about buying your glasses online, consult first with trusted eye doctors in Durham, NC like those from the North Carolina Eye, Ear, Nose & Throat.”

How Does Vision Work?

The cornea is a transparent layer that covers the front of the eye. Not only does it keep external particles away from the eye, it also acts as a “window” that controls the light entering the eye. The cornea possesses the ability to change shape and contributes to the positioning of light rays that enter the retina. These light rays are then translated into impulses which are processed and interpreted as images by the brain.

The cornea may stiffen and lose the ability to change shape as we grow older. Since this condition prevents light from focusing on the retina, a person affected will experience a refractive error that leads to poor vision. A refractive error is classified into three: myopia or nearsightedness, hyperopia or farsightedness, and astigmatism, which makes all objects at any distance appear blurry or distorted in the eyes of the affected individual.

A common method to correct a refractive error is to wear prescription glasses or contact lenses daily or whenever necessary. They can bend the light entering the eyes and properly focus it onto the retina. A more permanent way to correct refractive errors is through LASIK eye surgery, a procedure that involves an excimer laser that permanently reshapes the cornea.

How To Prevent Computer Vision Syndrome

According to a survey by enterprise mobility company Good Technology, most American employees render an hour of overtime per day, totaling to an extra whole day of work every week. It seems that the fear of losing one’s job in this tepid economy makes laborers work harder than ever. With longer working days, people are more prone to stare into their computer screens. This means more work for the eyes because text on a computer screen is not as sharp as those on a printed page. Screen glare and reflection also hamper proper viewing.

This eye discomfort suffered by those who sit in front of a computer day in and day out is known as the “Computer Vision Syndrome”. Some of its symptoms include eyestrain, blurred vision, dry eyes and headaches.

To avoid this, people can adjust their computer screens about 4 to 5 inches below eye level, thus limiting the cornea’s exposure to the screen. Sitting 18-24 inches away from a computer can also reduce eye strain, as does taking a quick break every 15 minutes or whenever the eyes feel tired. Of course, regular check-ups with an eye doctor is important to ensure healthy eyes that will perform well even on the longest work days.
