Key Takeaways
- The shape of your eye and cornea can determine how clearly you see objects up close and far away.
- Myopia makes distant objects blurry while hyperopia makes close reading difficult.
- Routine eye exams help catch vision changes before they disrupt your daily life.
- Glasses and contact lenses can manage blurry vision and help you see clearly day to day.
You might find yourself squinting to read a distant highway sign on your morning commute. Or perhaps you stretch your arms out far just to read a text message on your phone. Our team at Total Vision Riverside knows these daily frustrations usually point to a simple issue with how your eyes process light.
Refractive errors are problems with where the light coming into your eye lands. Common examples include nearsightedness, farsightedness, astigmatism, and presbyopia, which can happen when the physical shape of your eye prevents light from focusing correctly on the back of your eye. Refractive errors can be detected during an eye exam and corrected with prescription glasses or contact lenses.
The Basics of Refractive Errors and Eye Health
How Eye Shape Changes Your Sight
Clear sight happens when light enters your eye and lands directly on the retina. Your retina is the light-sensitive tissue at the back of the eye, and for you to see a clear image, light rays need to land on the center of it.
In some cases, changes in your eye can impact where light lands. This is a refractive error, and routine visits to the eye doctor can help track these subtle changes in your eye shape over time.
Nearsightedness and Farsightedness Facts for Your Family
Myopia
Myopia, commonly called nearsightedness, stands out as a highly common vision issue across all age groups. It’s most often caused by the eye growing too long from front to back, which causes light to land in front of the retina instead of directly on it. This makes distance vision blurry.
Proactive eye exams can catch these subtle changes early so you can get back to seeing clearly without constantly squinting. At Total Vision Riverside, we also offer myopia control, which aims to slow down the progression of myopia in children and support their long-term sight.
You might spot the early signs of this issue in your own home. If you notice your child constantly squinting at the television or struggling to read the whiteboard at school, it might be time to bring them in for an eye exam.
Hyperopia
Hyperopia, or farsightedness, is the opposite of myopia. With hyperopia, the eye may be shorter than average, causing light to focus behind the retina. This can make it harder to see clearly, particularly up close.
Astigmatism and Presbyopia
Astigmatism
Astigmatism occurs when the cornea or lens has an uneven curvature. Instead of focusing light evenly onto the retina, different parts of the eye focus light differently. This can cause blurry or distorted vision at both near and far distances.
Presbyopia
Presbyopia is a common age-related vision change that happens to almost everyone over 40. Inside your eye is a flexible lens that brings distant and near objects into focus. As you age, this lens loses flexibility, becomes rigid, and struggles to shift focus between distant and near objects.
The result is that small print on a restaurant menu or a medicine bottle may become more difficult to read, and you may find yourself holding objects at arm’s length.
Signs and Symptoms
If you notice any of the following signs, you may have a refractive error. These signs can indicate a need for an eye exam:
- Your vision appears blurry.
- You see double images or harsh glare around bright street lights at night.
- You feel heavy eye strain, which can be a sign of digital eye strain.
Correction Methods from an Eye Doctor in Riverside
Glasses and Contact Lenses
Prescription glasses can effectively manage refractive errors, helping you see clearly again. A pair of prescription glasses designed for your eyes helps you read your computer screen or drive comfortably.
Contact lenses sit directly on your eye to provide clear vision without frames sitting on your face. They move naturally with your eyes for a comfortable viewing experience. The eye doctor can have a discussion with you about your hobbies and job demands to match your lenses to your life.
Many people find that they like both glasses and contact lenses, and use both for various occasions.
Modern Vision Correction Options
Laser eye surgery reshapes the cornea to help light focus on the retina correctly.
Progressive lenses offer another practical option for seamless daily distance transitions. They blend multiple prescriptions into one lens so you can drive and read without switching your glasses.
