Top 10 Commonly Confused Words in Optometry

Top 10 Commonly Confused Words in Optometry 1. Myopia vs. Hyperopia Myopia and hyperopia are two common refractive errors. Myopia, also known as nearsightedness, refers to the ability to see nearby objects clearly, while distant objects appear blurry. On the other hand, hyperopia, or farsightedness, causes distant objects to be clearer than those up close. Understanding these terms is essential for prescribing the correct lenses. 2. Conjunctivitis vs. Keratitis Conjunctivitis and keratitis are both eye inflammations, but they affect different parts. Conjunctivitis, often called pink eye, is the inflammation of the conjunctiva, the clear tissue covering the front of the eye. Keratitis, however, is the inflammation of the cornea, the transparent front part. While both conditions require attention, their treatments may vary. 3. Cataract vs. Glaucoma Cataract and glaucoma are two common eye conditions, but they involve different parts of the eye. A cataract refers to the clouding of the eye's natural lens, leading to blurry vision. Glaucoma, on the other hand, is a group of diseases that damage the optic nerve, often associated with increased eye pressure. While cataract surgery is a common treatment, glaucoma may require a different approach.
