Refractive Errors: Types, Symptoms & Treatments
Refractive errors occur when the eye cannot focus light properly, leading to blurred vision. They are among the most common causes of visual impairment in Ghana but are easily correctable with the right care.
What Causes Refractive Errors
Changes in the shape of your cornea, your lens or your whole eye can cause refractive errors. Which type of refractive error you have depends on how your eye is shaped. They can also develop as you get older. Aging eyes can develop a refractive error you didn’t have when you were younger. Some people develop a refractive error after surgery to remove cataracts from their eyes.
Types Of Cataract
- Myopia (Nearsightedness): Distant objects appear blurry.
- Hyperopia (Farsightedness): Close-up objects are hard to see
- Astigmatism: Vision is distorted due to irregular eye shape.
- Presbyopia: Age-related difficulty seeing things up close.
Symptoms
Symptoms of cataracts includes:
- Blurry vision.
- Eye strain or headaches
- Difficulty seeing at night.
- Squinting or rubbing eyes frequently
Diagnoses & Treatments
The good news? Refractive errors can be easily diagnosed with a basic eye test and treated with:
- Prescription eyeglasses
- Contact lenses
- Refractive surgery (for select cases)
Affordable vision screening services are increasingly available through clinics, outreach programs, and NGOs across Ghana.
Protect Your Sight
- Get your eyes tested annually
- Ensure children receive school vision screenings
- Avoid self-prescription of glasses from street vendors
Conclusion: Refractive errors are common but easily managed. Don’t ignore blurry vision—visit an eye clinic or optometrist near you for proper diagnosis and affordable treatment.
When To See A Doctor
Make an appointment for an eye exam if you notice any changes in your vision. If you develop sudden vision changes, such as double vision or flashes of light, sudden eye pain, or a sudden headache, see a member of your health care team right away. Request an appointment

Hospital is the real deal! I couldn't have asked for more than this. If you aren't sure, always go for hospital. Hospital was worth a fortune to my company.
