Using eye exam equipment, Dr McClunan is able to detect the most common vision problems, which include:

• Nearsightedness: Nearsightedness is a common problem that happens when an image is focussed just in front of the retina and doesn't create a clear picture. Objects directly in front of the eye are clear, while objects further away in the distance are blurry. The cornea and lens are vital structures that work together to produce clear images on the retina. Nearsightedness occurs when the strength of the cornea is too strong or the length of the eye is too long. Spectacles, contact lenses, LASIK laser or surgery can be used to treat nearsightedness.
• Farsightedness: When the cornea is flat or the eyeball is short, light is focussed at a point behind the retina. We refer to this shortfall as farsightedness, also known as hyperopia. Images of objects in front of the eye are hazy while those far away can be seen. Like nearsightedness, the effects of farsightedness can be resolved through the use of spectacles, contact lenses, LASIK laser or surgery.
• Astigmatism: When the cornea is shaped like a rugby ball rather than a soccer ball, light is not focussed properly in the eye. Two images form instead of one, which results in a single blurry image. Often, astigmatism accompanies nearsightedness and farsightedness. Spectacles, contact lenses, LASIK laser or surgery correct this issue. 
• Presbyopia: Presbyopia is the inability to see objects near the eye. Age is the primary reason for presbyopia which occurs in a person's forties and worsens during the late sixties. As we age, our eye lenses harden. Our lens becomes less flexible and, therefore, cannot alter its shape to focus on pictures that are close to the eye. Spectacles, contact lenses, LASIK laser or surgery, can correct presbyopia in certain patients.
