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."

LASIK: What You Need to Know

People with very poor vision have different methods at their disposal to correct it such as wearing prescription glasses or contact lenses. However, there is a more effective way to correct poor vision and permanently eliminate the need for glasses or contacts altogether: the LASIK eye surgery. A long-standing procedure, the LASIK or “Laser-Assisted In Situ Keratomileusis” is a common surgical procedure performed to treat hyperopia or farsightedness, myopia or nearsightedness, and astigmatism.

The eye is covered by a transparent layer called the cornea, which is responsible for controlling the entry of light into the eye. As we age, the cornea starts to lose the ability to change shape. Thus, the LASIK eye surgery calls for the use of an excimer laser to reshape the cornea, allowing for the refocusing of the light entering the retina and improving one's vision in the process.

Prior to LASIK surgery, patients have to undergo a medical evaluation. A thorough exam will be administered to check the benefits or risks of the surgery. Information pertaining to the expectations and responsibilities of a candidate before and after the surgery will also be provided. If you are qualified for the surgery, it is highly recommended to give yourself plenty of time to review or to ask the necessary questions before signing a consent form.

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.
