A normal sign of aging that’s impossible to ignore and difficult to hide, presbyopia usually occurs beginning at around age 40 – you’ll know when it’s happening to you as you’ll need to hold objects or reading material further away from the eyes in order to focus. The eye’s lens stiffens with age, so it’s...
Project Category: Refractive Error
Myopia (Short-Sightedness)
The most common refractive error of the eye, short-sightedness or myopia occurs when light entering the eye focuses in front of the retina instead of directly on it. Corrected either by glasses, contact lenses or LASIK, near-sighted people typically have difficulty reading road signs and seeing distant objects clearly, but see well for close-up tasks...
Hyperopia (Farsightedness)
More commonly known as farsightedness, hyperopia occurs when light rays entering the unaccommodating eye fall behind the retina as opposed to on the retina. Depending on the degree of hyperopia, patients will have blurred distance or near vision and may complain of headaches and tired eyes.
Astigmatism
Astigmatism occurs when the cornea or lens is irregularly shaped – as a consequence, light rays entering the eye do not form a focused image on the retina. Depending on the degree of astigmatism patients may complain of blurry vision, fatigue and headaches, but astigmatism can be treated with glasses, contact lenses or refractive surgery.
Amblyopia
An early visual development problem occurring before the age of nine, amblyopia – more commonly known as “lazy eye” – is the most common cause of visual impairment among children, affecting about two to three out of every 100 children. It’s also the most common trigger of monocular (one eye) visual impairment among young and...
