It’s a common question that many people wonder about when getting new glasses or contact lenses Can eyes be over corrected This is a valid concern, as the goal of corrective eyewear is to provide clear and comfortable vision, not to create new problems. Let’s explore what happens when vision correction goes too far.
Understanding Over Correction
Over correction happens when the prescription for your eyeglasses or contact lenses is stronger than what your eyes actually need to see clearly. Instead of perfectly focusing light onto your retina, the lens bends the light too much, causing it to focus in front of the retina. This can lead to a variety of symptoms, often making your vision worse than before you got the correction.
Here are some key aspects of over correction:
- Myopia (Nearsightedness) Over Correction This is the most common type of over correction. If you are nearsighted and get lenses that are too strong, distant objects will appear blurry, and close-up objects might also be affected.
- Hyperopia (Farsightedness) Over Correction For those who are farsighted, over correction means their lenses are not strong enough. This can lead to eyestrain and difficulty focusing, especially when reading or doing close work.
- Astigmatism Over Correction Astigmatism involves an irregularly shaped cornea. Over correcting for astigmatism can distort vision at all distances, making straight lines appear curved or tilted.
The consequences of over correction can be quite bothersome. Your eyes constantly try to adjust to the incorrect lens power, which can result in:
- Eyestrain and fatigue
- Headaches
- Blurred vision, both near and far
- Dizziness or nausea
- Increased sensitivity to light
It’s important to understand that your eyes are designed to work optimally with the correct prescription. The importance of getting an accurate prescription from a qualified eye care professional cannot be overstated, as it directly impacts your visual comfort and overall eye health.
| Symptom | Likely Cause |
|---|---|
| Distant objects blurry | Myopia over correction |
| Headaches after reading | Hyperopia over correction or under correction |
| Double vision or distorted lines | Astigmatism over correction |
If you suspect your current glasses or contacts are causing any of these issues, it’s crucial to have your prescription re-evaluated. Your eye doctor will perform a comprehensive eye exam to determine the precise power needed for clear and comfortable vision.
