The Origin of Eyeglasses


Eyeglasses in Halifax, NS, allow people to see clearly. They have become a fixture in our modern world, and they are just as much fashion statements as they are tools. How did humanity develop the glasses we have come to depend on today? Let’s go over the origin of eyeglasses.

The first inventor of eyeglasses is unknown. However, we do have a general starting point in Ancient Rome. During this time, the Romans discovered the ability to use a glass to magnify small text. This would later lead to the invention of the earliest magnifying glasses.

In the 13th century, Italian artisans placed glass-blown lenses into wooden frames. In daily use, these early glasses were held in front of the face or balanced on the bridge of the nose. These primitive glasses were a popular tool used by monks as they studied and wrote manuscripts. It wouldn’t be until the 1700s where we would see the addition of temples to the frames, paving the way for the eyeglasses we recognize today.

Afterward, notable developments in eyeglass technology ensued. Benjamin Franklin would invent bifocals, allowing for near- and far-sighted vision. Then, the “scissor spectacles,” which allows glasses to be carried in coat pockets. The Industrial Revolution in the 1800s and 1900s would allow for the mass production of glasses and their frames, making corrective lens treatment more accessible.

As the 20th century moved on, glasses technology shifted toward making them more fashionable and practical in daily life. People experimented with different materials and colors, allowing wearers to coordinate their glasses with outfits. Sunglasses would also make their debut during this century, adding much-needed eye protection during the day.

Today, lens and frame manufacturers are discovering new ways to make eyeglasses more fashionable and easy to wear. Innovation is the name of the game. From titanium temples to flexible frames, the future looks clear for eyeglasses.

How Traumatic Brain Injuries Affect Your Eyesight


Your eyes are part of your nervous system, which is connected to the brain. Suffering from a concussion or other traumatic brain injury can adversely affect your vision, causing a snowball effect of complications. In this post, we’ll go over how a brain injury in Halifax can impair your vision.

One of the most common conditions that arise from concussions is Post-Traumatic Vision Syndrome. This condition may also be abbreviated to PTVS. It is a collection of signs and symptoms that affect your vision, sensory perception, and motor skills. Common signs that someone is suffering from PTVS include:

  • Light Sensitivity
  • Inability to Concentrate
  • Difficult Coordinating Eyes
  • Inability to Focus
  • Double Vision or Blurred Vision
  • Headaches

Your eyes interpret what you see for your brain to process. When the brain sustains multiple injuries over time, parts of it can become damaged. As a consequence, you may be unable to perceive images. These complications don’t just make it difficult to see--it also makes it harder for your brain (and its associated systems) to interpret the world around you.

Treatment for Post-Traumatic Vision Syndrome is available. However, the best treatment is always to take preventative measures. The most common causes of concussions and brain injuries arise from car accidents and contact sports. If avoiding these activities is impossible for you, it is recommended to observe all safety precautions and to exercise proper discretion.
