Refractive error is a condition characterized by blurred vision due to the inability of light rays to focus directly on the retina. The main types of refractive error include myopia, hyperopia, and astigmatism. Myopia or nearsightedness occurs when light rays focus in front of the retina whereas hyperopia or farsightedness occurs when light focuses behind the retina. Astigmatism occurs as the result of an irregularly shaped corneal lens that forces light to focus in several different areas. Fortunately, individuals with refractive errors can benefit from wearing contacts or prescription glasses. Read on for tips on determining which vision correction option is right for you.
Certain factors may interfere with your ability to wear contact lenses. Individuals who suffer from eye allergies or work in environments with dust or chemicals may experience eye irritation while wearing contacts. Contact lenses are also not ideal for individuals with overactive thyroids, uncontrolled diabetes, or severe hand arthritis. Glasses are a great alternative and come in a wide variety of colors, styles, and materials to suit your specific needs and aesthetic preferences.
It is important to take your lifestyle factors into consideration when choosing between contact lenses and glasses. Individuals who lead active lifestyles and participate in sports may prefer contact lenses, as they provide good peripheral vision and reduce the risk of broken frames.
Wearing contacts will require a higher level of devotion to hygiene, as they will need to be cleaned before and after each use. However, many contact lens solutions now sterilize your lenses without the need to rub or massage the lenses themselves.
The best way to determine which option is right for you is to consult with your Canada optometrist. For more information on your eye wear options or to set up an eye care examination, contact FYidoctors.
