Saturday, March 5th is one of the few Saturdays we are open if you want to come by to look at eyewear or pick up an order. The exam schedule is full, but we are taking appointments for our next Saturday, on April 2nd.

Bumps on the Eye

Pinguecula and pterygia are 2 types of bumps that grow on the white of the eye. They are benign and rarely affect vision. They can become irritated and red though.
A pinguecula is limited to the conjunctiva, the white of the eye. A pterygium will be on the cornea, the clear part of the eye and the conjunctiva. A pterygium is more vascular.
Exposure to the sun, dust and wind contribute to the formation and worsening of the bumps. Wearing good sunglasses will offer protection.

What about Blue Light?

Blue light has the shortest wavelengths and the highest energy. It is both beneficial and dangerous.
1. Blue Light is Everywhere
Sunlight is the main source of blue light. There are many man-made sources of blue light that include fluorescent and LED lighting and flat-screen televisions.
2. HEV Light Rays Make the Sky Look Blue
The short-wavelength, high-energy light rays on the blue end of the visible light spectrum scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere.
3. The Eye is not very Good at Blocking Blue Light
Virtually all visible blue light passes through the cornea and lens and reaches the retina.
4. Blue Light Exposure may Increase the Risk of Macular Degeneration
The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This damage resembles the changes of macular degeneration.
5. Blue Light Contributes to Digital Eyestrain
Shorter wavelength and higher energy light scatters more easily than visible light so it is not as easily focused. The eye strains to see clearly.
6. Not All Blue Light is Bad
Blue light is very important in regulating circadian rhythm – the body’s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. On the flipside, too much blue light, especially late at night can contribute to insomnia.
 If you wear glasses routinely while reading and using a computer there are special non-glare coatings that also block the blue light.

Fast Facts
Electronic  devices emit blue light that can cause eye strain and may lead to eye problems.
The most common eye color is brown – 55% of the population. Genetics and pigment concentration are responsible for the color of a person’s eyes. High concentrations of melanin result in darker eye colors.
PRESBYOPIA occurs when the proteins in the lens of the eye become less flexible. The loss of lens elasticity makes it difficult to focus up close. Most people notice the onset of presbyopia during their forties.
