If you’ve ever squinted to see a street sign or held your book at arm’s length to read the words clearly, you’re already familiar with the daily challenges of myopia (nearsightedness) and hyperopia (farsightedness). Both cause blurry vision, and both can make day-to-day activities challenging. As 2 of the most common vision conditions, they may sound similar, but they affect vision in opposite ways.
Simply put, myopia causes distant objects to appear blurry, while hyperopia makes close objects appear blurry. Your optometrist can correct both of them with glasses or contact lenses.
How the Human Eye Sees
The human eye is an incredible organ that works much like a camera to create clear images. Here’s a quick breakdown of how vision works:
- The clear, outermost layer of the eye, called the cornea, bends incoming light toward the lens.
- The iris controls the size of the pupil, allowing just the right amount of light to enter.
- The lens adjusts its shape to fine-tune focus, directing light to the back of the eye.
- The retina at the back of the eye contains cells that convert light into electrical signals for processing.
- The optic nerve transmits those signals to the brain, which interprets them as images.
For sharp, clear vision, light rays must focus precisely on the retina. But when the eyeball’s shape or the curvature of the cornea differs from normal, the result is refractive errors—myopia or hyperopia.
What Is Myopia?
Myopia, or nearsightedness, occurs when the eyeball is slightly too long or the cornea is too curved. This causes light to focus in front of the retina rather than directly on it, leading to blurry distance vision while nearby objects remain sharp. This can be caused by a range of factors, such as:
- A family history of myopia
- Extended screen time
- Not spending enough time outdoors as a child
If left uncorrected in children, myopia can progress, increasing the risk of serious eye conditions later in life, such as:
- Glaucoma
- Retinal detachment
- Cataracts
- Macular degeneration
What Is Hyperopia?
Hyperopia, or farsightedness, is essentially the opposite of myopia. It occurs when the eyeball is too short or the cornea is too flat, causing light to focus behind the retina. This results in blurred near vision, making activities like reading or crafting harder, while distance vision remains relatively clear.
Experts aren’t what causes entirely sure what causes hyperopia, and many people may have some degree of it without ever knowing. It seems to be that, much like myopia, hyperopia may be caused by genetic or environmental factors.
Hyperopia is similar to another vision condition, presbyopia. Presbyopia also causes blurry near vision, but it’s caused by the eye’s lens naturally hardening and typically affects people over 40.
Myopia & Hyperopia’s Affect on Daily Life
While myopia and hyperopia can appear to be opposites, both conditions can significantly affect daily activities. Here are some ways these conditions can make your day more difficult:
- Driving: If you’re nearsighted, reading distant road signs might be a struggle. If you’re farsighted, focusing on the dashboard might be tricky.
- Reading and screen time: Farsightedness can make things like reading or scrolling through your phone tiring and frustrating.
- Recreational activities: Whether it’s sports or hobbies that need sharp vision, uncorrected eyesight can take the fun out of them.
Dealing with blurry vision isn’t just uncomfortable—it can lead to eye strain and even make you less productive over time. Address these issues early so you can get the most out of your day.
Diagnosing Refractive Errors
Regular eye exams are important for uncovering issues like nearsightedness (myopia) or farsightedness (hyperopia) early on. Here’s what your optometrist will typically do during an exam:
- Check your vision with a visual acuity test to see how well you focus at different distances.
- Fine-tune your prescription with a refraction test.
- Take a closer look at your retina and optic nerve using an ophthalmoscopy.
For healthy, happy eyes, try to schedule exams every year for kids, every 2 years for adults, and yearly again once you’re 65.
Management & Corrective Options
Fortunately, both conditions are highly manageable. The most common fix is corrective lenses, which provide clear vision customized to your needs. They’re simple to use and come in a variety of styles to match your preferences and lifestyle.
For a more lasting solution, laser eye surgery procedures like LASIK or PRK can reshape the cornea and offer long-term correction. These options are ideal for adults with stable vision, while children may have to go a different route.
Myopia Management for Children
Myopia control focuses on slowing down myopia progression in children.
Since myopia tends to worsen during childhood, starting early can make a big difference in reducing the risk of serious eye issues later on. Common treatments include:
- MiSight Daily Contacts
- ACUVUE Abiliti Soft Contacts
- Low-dose atropine eye drops
- ZEISS MyoCare Lenses
These approaches typically work by changing how light focuses on the retina, which can slow the eye’s natural growth. Pairing these treatments with healthy habits, like spending more time outdoors and cutting back on screen time, can go a long way in protecting your child’s vision for the future.
