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.
