All About Macular Degeneration

If you are over the age of 50, then you are at risk of developing Macular Degeneration (AMD). This condition causes a gradual vision loss that is the result of macula deterioration. The macula is located near the center of the retina and is responsible for central vision and sending and receiving image signals to and from the optic nerve.

Symptoms of Macular Degeneration

People that have this condition are usually unaware of it until they start to experience drastic and sudden changes in their vision. Although the disease occurs in stages and is not curable, early detection can significantly improve one’s prognosis.

Symptoms include:

• Vision loss
• Yellow deposits in the retina
• Pigment loss in the retina
• Trouble seeing and recognizing shapes, objects and depths
• Trouble focusing

Many people can live happy and productive lives with the assistance of various treatment options, such as medications, visual aids and laser therapy.

Macular Degeneration is the leading cause of vision loss in the United States. It affects more than 10 million people each year. Although it generally affects people who are over the age of 50, people that smoke, have a family history of the disease, or are of Caucasian descent have a much higher chance of developing this condition in their lifetime.To learn more about getting your eye checkup in Chula Vista, please visit this website.

Tips for Finding the Right Sunglasses

While you’d be hard pressed to find someone not wearing sunglasses on a sunny day at the beach, their history isn’t very old. Inexpensive, mass produced sunglasses were first offered in 1929, when Sam Fosterbegan selling them in New Jersey. A decade later, 20 million had been sold in the United States, although most wore them as a fashion statement.

Looking stylish may be a reason for choosing protective eyewear, but there is a much more important one: eye health. Just as the sun can damage skin, it also harms the lens of the eyes. The more exposure your eyes receive, the higher the chance of developing cataracts and possibly macular degeneration. While the former can be removed surgically, the latter is a permanent problem that eventually leads to blindness. Cosmetically speaking, sunglasses can also help slow down the formation of wrinkles such as crow’s feet.

When looking for sunglasses, experts suggest choosing those that reflect or filter out 99 percent of UVB and 95 percent of UVA rays.The darkness of the lens is not a good indicator of protection. In fact, a darker lens can be more harmful than no glasses at all because they force the eye to dilate, thus allowing in more unfiltered radiation.

Price is not an adequate predictor, either. For the best protection, lenses should fit closely to the face with little light reaching your eyes from any direction. If you want to minimize color distortion, choose red, gray, green or brown lenses. Yellow is considered the best for defining objects, and work especially well for skiers, hunters and pilots. Blue and purple are simply used for looks.

The manufacturer will usually label the sunglasses so you know what protection they offer. If you are unsure, an optometrist can check them for you. Also, remember that no standard sunglasses are powerful enough to protect your eyes from looking directly at the sun.

Of course, you want to look good in your eyewear. Once you’ve determined which ones offer the best protection, you’ll need to choose a style. There are mirror shades, which have a mirror coating on the surface; aviators, which are the teardrop-shaped lens favored by pilots and military; wayfarers, the ones made popular in the 1950s by movie stars like Audrey Hepburn; and oversized frames, which are popular among female celebrities.

Whatever style you decide, be sure that you are getting the protection you need to keep your eyes healthy while you’re outdoors. To find out more about stylish shades in El Cajon, please visit this website.

A Brief History on Eye Glasses

During the early days of civilization, cultures all over the world used various visual aids, such as water bowls and vision stones to magnify images. Although the concept of glasses dates back to the early days of Roman civilization, it wasn’t until 1284, that the first wearable pair was invented by Salvino D’Armate. At that time, glasses were worn on the bridge of the nose, and prescribed for people who were farsighted.

Eye Glasses in Italy

During the 14th century, Italy gained much prominence in the eyeglass industry. They became world renowned for the quality and artistic quality of eye glasses they produced. Five-year eyeglasses were even invented because of the belief that poor vision began at the age of 30 and prescriptions only needed to be updated every five years.

Lenses

By the time the 17th century rolled around, convex and concave lenses were invented. Using these lenses, glasses were created to treat people who required single lenses to see up close or far away. Benjamin Franklin, who suffered from both myopia and presbyopia, invented bifocals in 1784 so he wouldn’t have to switch back and forth between glasses. And in 1825, cylindrical lenses were created for people who suffered from astigmatism.

Today, eye glasses are used all over the world. They come in many different prescription strengths, colors, styles and price ranges.

What Is Glaucoma, and How Can It Be Treated?

Glaucoma is a condition that usually occurs when the eye is unable to maintain balance between intraocular fluid – or fluid inside the eye – and that which drains away. Intraocular fluid keeps your eye functioning properly and helps to maintain its spherical shape. But when too much fluid pressure builds up, glaucoma develops as the eye pushes on and eventually causes permanent damage to the optic nerve.

Glaucoma occurs in two forms. Narrow-angle glaucoma is a rare, acute condition that requires immediate treatment to save the patient’s vision. Open angle glaucoma, the more common form of the condition, is degenerative, meaning that it worsens over time.

A recent research breakthrough revealed that the impairment caused by the latter condition actually begins in the brain, as the optic nerve begins to lose connectivity, and travels back to the retina. In some people, glaucoma can occur even without high intraocular pressure; in these cases, unusually sensitive optic nerves break down even under normal amounts of pressure.

Open angle glaucoma treatment focuses on preventing further loss of vision, which is permanent once it occurs. Treatment options include:

  • Medications to slow the production of fluid
  • Drops that are absorbed directly into the eye to help with fluid regulation
  • Surgery to create an opening from which excess fluid can drain
  • Laser surgery to help the eye’s drainage system function more effectively

In the U.S., doctors typically treat patients with medications and eye drops before suggesting more invasive techniques such as traditional or laser surgery.

Do You Have an Eye Infection?

Don’t overlook eye irritation. Eye infections come in many different symptoms and consequences, so always check with an optometrist if you’re feeling any discomfort.

If you’re experiencing discomfort in your eyes, it can sometimes be difficult to know when you might be dealing with an infection. Eye irritation is common in cases of allergies, colds and flu or even just dust. Contact lenses that are torn or have even just shifted can cause discomfort as well, so be sure to remove your lenses anytime you feel uncomfortable. Knowing how to tell the difference between normal irritation and infection can help you get to an eye doctor sooner to get the treatment you need to start feeling better faster.

When you have itchy, red eyes, flush them out with water to see if the irritation is being caused by a speck of foreign material. You shouldn’t rub your eyes when they itch, but if you already have, you may have inadvertently caused some mild swelling. If you’re still experiencing pain, discomfort, or swelling after flushing out your eyes, there may be a more serious problem, and you should see your eye doctor.

Frequent headaches, or an unusual sensitivity to light, could also be a sign of infection, especially if it’s accompanied by other symptoms, such as blurry vision or a burning sensation. Also be on the lookout for visible signs. Yellow discharge or pus is a sure sign of infection, especially if it becomes crusty and hardens over the eye. White sores in the corner of the eye or on the surface of the iris is another obvious symptom. If you have a fever, and your only other symptom is discomfort in your eyes, you also may have an eye infection.

While these signs are easy to notice and feel, you also should be aware that some of the most damaging infections may not include pain or discomfort at all. If your vision blurs often or you feel as though your vision is deteriorating, you may have a disease that is damaging your retinas or optic nerves. If you suspect anything unusual happening in your eyes, don’t wait to have it checked out. Eye problems that fail to be diagnosed can lead to serious consequences.

Because there are so many different types of eye infections, it’s impossible for you to diagnose the cause on your own. Infections like pink eye are also extremely contagious, so you’ll want to catch it early on before you spread it to others. An eye doctor can take samples and evaluate your eyes up close to determine the cause of your discomfort and prescribe the appropriate treatment.
