Our eyes and vision are amazingly complex and they have many components. We hope this will be an introduction into your world of vision and how our eyes work. We are here for your total eye care.

How does our Vision work

Have you ever heard the adage that we don’t see with our eyes, “we see with our brain”? Well, it’s true. The eyes are responsible for transmitting images to the brain, by focusing on an object and understanding what is the object. It is the shape and size of your eye that determines whether our eyes are able to focus on an object, or if corrective ophthalmic lenses are necessary. When your eye focuses on an object an image is formed. The brain then processes the object projecting a virtual image. Optical scientists rely on our knowledge of our eyes and the brain. This will determine how it processes images to design the best possible lenses to correct an individual’s blurry vision. The human vision system is complex consisting of two sets of lenses, the cornea and crystalline lens.

The cornea is in the front of the eye and is responsible for focusing on an image. The crystalline Lens is found in the anterior chamber of the eye. This focuses on an image, but adjusts your eyes to see objects far away, or within a short distance as well as close up. The cornea and crystalline lens of the eye both carry a curved shaped, making our eyes appear round. When the cornea and crystalline lens of the eye are of normal size and shape, we see images clearly. If your cornea is too curved or not curved enough, they have a refractive error. A refractive error means that there is an error in getting the eye to focus clearly on an image. All of these condition will be determined during your eye examination.

How Do We Correct Our Vision

Ophthalmic Lenses help us focus on an object and perceive it clearly. Refractive errors include Myopia, Hyperopia and Astigmatism. If you are Myopic, Hyperopic or Astigmatic, you will need an ophthalmic lens to assist your eyes to see clearly. If your eyes also need help focusing on images close up, you have a condition known as presbyopia. This means that your crystalline lens, due to the natural aging process, can no longer focus and adjust your focus as it used to. In this case, additional magnification is needed to focus up close. This magnification can be obtained through reading glasses, bifocals, or progressive addition lenses.

The eyes are considered by many as the most precious of senses. We have one set and it is vital that we care for and protect them. No matter what refractive error one may have, clear, concise vision is possible with a great eyeglass lens. Improvements in science and technology allow lens engineers to recreate vision through lens designs. We are here for all of your vision needs.
