Here is a list of the most Frequently Asked Questions that I receive.

1. When did you qualify as an optician ?

I qualified in 1979 and went to work immediately for what was the busiest practice in the country, Mc Givney's in Henry Street. The company celebrated 150 years in businrss a few years ago - it was founded in 1833. Sadly, it closed its doors for the last time in 2008.

2. I am able to see perfectly in the distance but I can't read anything up close. Can you do anything to help me ?

When we hear this question, it is usually from someone who is over 40 years old. When we do an eye examination we usually find that they do indeed have perfect or near perfect vision for the distance, driving, TV etc., but their near vision is impaired to a greater or lesser degree. This condition is called PRESBYOPIA and results from the hardening of the crystalline lens inside the eye over time. The onset is usually in the early to mid forties. The solution is to make READING GLASSES or BIFOCALS.

3. I can see very well up close but anything further than arm's length is a blur. Am I going blind ?

The concern and worry here is very understandable. The problem is, in essence, the opposite one from the last question. The condition is called MYOPIA (SHORTSIGHTEDNESS) and is because the axial length of the eyeball is longer than the focal length of the optical system of the eye. This results in a blurred image falling on the retina. This condition can be remedied by using minus lenses otherwise known as negative or concave lenses. They effectively lengthen the focal length of the eye and cause the image falling on the retina to be sharp.
