Both cataracts and glaucoma can severely impair a person's ability to see. Although a medical expert can't tell for sure that these two eye disorders are identical or even similar, they do have the same ultimate outcome: blindness if not treated quickly enough.
This article, following a Healthline article, will compare certain information about each condition to determine which is more severe and more frequently results in blindness. Relax and take in this information as you acquire new knowledge.
What exactly is glaucoma?
According to healthline Increases in intraocular pressure, the leading cause of glaucoma, are a leading cause of blindness in the Western world. Poor drainage of fluid or replenishment of aqueous humour in the eyes can lead to ocular hypertension, which can in turn damage the optic nerve and result in vision loss. Eye pain, eye redness, unexplained fuzzy vision, etc. are common glaucoma symptoms that may appear before complete vision loss.
Contrarily, cataracts are characterized by clouding of the eye's lens. The lens in the eye plays a crucial role in focusing incoming light onto the retina at the back of the eye. Yet, when the lens of the eye becomes clouded by fatty deposits, vision becomes blurry and colors become muted. Cataracts are the primary reason why seniors go blind. Cataract symptoms include, but are not limited to, cloudy vision, faded colors, hazy vision that does not improve with glasses, high sensitivity to light, and so on.
Which One of These Is Worse?
Now we get to the crux of the matter: which is worse? None, is the correct answer. They pose an equal risk if ignored. Cataracts typically don't result in any pain, but glaucoma almost always does, along with redness and severe pain in the affected eye. Hence, they are the major causes of blindness in adults, and they have some characteristics, such as being more prevalent in older persons and resulting in blurry vision that progressively worsens.
