Ask anyone about which sense they fear losing the most, and a majority would definitely give “eyesight” as their answer. It’s not difficult to understand why: humans function and react based mainly on what they can see. Eye doctors can attest that only with proper care and maintenance will our eyes serve us well in our lifetimes, with little or no impairment whatsoever.
Eat right to see right
Proper nutrition will help keep your vision clear as well as maintain overall health. Vegetables like carrots contain Vitamin A that is beneficial to eye health; a deficiency in this important nutrient often results into xerophthalmia, or drying of the eyes which could lead to permanent blindness. Food that contains antioxidants and zinc is also good for the eyes.
If you were born with defective eyes, you could develop congenital eye disorders such as astigmatism, myopia, and glaucoma. These can be corrected via surgery, eyeglasses, or eye drops. Patients with cataracts and macular degeneration should consult an ophthalmologist.
Each time you go out into the world, anything from a speck of dust to sunlight can result in eye discomfort and might even escalate to something serious. Use protective eyewear when travelling or working with industrial equipment to avoid flying debris. Dark sunglasses with ultraviolet-rated protection should be used to prevent damage caused by intense light. Also, avoid rubbing your eyes with your hands and reading in dim light.
Oftentimes, astigmatism is accompanied by various other vision problems, nearsightedness or farsightedness among them. What separates them though, is that the former is typically exhibited early in life through symptoms like eye strain, headaches, and the need to constantly squint. This problem can lead children to a difficult time at school.
Since it could show up in childhood, many experts purport that astigmatism just might be hereditary, where children inherit the refractive problems in their parents’ vision. Another known cause is injury or disease that happened to permanently damage the victim’s cornea function. The disease in this case is called keratoconus, since it makes the cornea thinner and more cone-shaped.
“There are several qualifications that an individual has to meet before this treatment can be administered. For one, your eyes’ prescription needs to be stable and not constantly changing; moreover, certain eye disease, especially when coupled with age, could also serve as a detriment. This is why efficient eye doctors in Durham, NC like those from North Carolina Eye, Ear, Nose & Throat should check your condition thoroughly before having you sign on to the procedure.
Of all your basic senses, losing your vision could perhaps be the most devastating. This is why science has seen to it that reliable treatments like LASIK are as safe as possible, for the benefit of those in dire need of getting their eye conditions fixed.”
“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.”
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.
Glaucoma has been tagged as one of the leading triggers of blindness in the United States. Some experts even advocate the use of marijuana to combat this condition. It is also a long-term danger that leads to permanent vision loss if not detected and treated at the early stages. It is important to know that there are several types of glaucoma that your eye practitioner is capable of addressing.
The most common type of glaucoma is the primary-open-angle glaucoma (POAG). In POAG, the eye has increased pressure exerted on it because blockages of aqueous fluid appear at some point in the eye’s drainage canal. Angle closure glaucoma occurs when the fluid canals are narrow or have fully sealed up. Nausea, blurred vision, and headaches are common symptoms for this type of glaucoma.
You can be diagnosed with normal-tension glaucoma (NTG) if tests show damage to the optic nerve even when the pressure on the canals are relatively low. Risk factors for NTG include hereditary conditions and even Japanese ancestry. Glaucoma can be also be secondary effects of other ailments such as diabetes and cataracts.
Glaucoma is often labelled as the “thief of vision” because you lose it over a long period of time. It is not the end, as early diagnosis and prevention will stop further damage.
