Myopia and Astigmatism: Key Questions Answered - Ophthalmology

More Info

---

Understanding myopia (nearsightedness) and astigmatism is crucial for managing your vision effectively, especially given your current prescription of -6.50 diopters in your left eye with 1.00 diopter of astigmatism, and -7.50 diopters in your right eye. Let’s address your questions one by one.

1. Wearing Glasses: It is generally recommended that individuals with myopia and astigmatism wear their corrective lenses consistently, especially when engaging in activities that require clear distance vision, such as driving or watching television. However, when it comes to reading or using your phone, you may choose to remove your glasses if you find it comfortable. Some people prefer to wear their glasses for all activities to avoid straining their eyes, while others may find that they can see well enough up close without them. Ultimately, it depends on your comfort and the severity of your refractive error.

2. Progression of Myopia: It is not uncommon for myopia to continue progressing into your twenties, especially if you have a higher degree of myopia. The increase of 100 diopters in your right eye over three years, along with the increase in astigmatism in your left eye, may seem concerning, but it can be within the range of normal progression for some individuals. Factors such as genetics, environmental influences (like prolonged near work), and overall eye health can contribute to this progression. While it is difficult to predict whether your myopia will reach -10.00 diopters or beyond, it is essential to have regular eye exams to monitor changes in your vision and discuss potential interventions with your eye care professional.

3. Effect of Cycloplegic Drops on Prescription: When you use cycloplegic drops (often referred to as "dilating drops"), they temporarily paralyze the ciliary muscle, which can affect your ability to focus on near objects. This can lead to a more accurate measurement of your refractive error, particularly for myopia. However, if you have your eyes dilated and then go for a refraction test the next day, it is important to note that the effects of the drops may still be present, potentially leading to a different prescription than what you would have without the drops. It is advisable to follow your eye care provider's instructions regarding the timing of your eye exam after using these drops to ensure the most accurate results.

In addition to these points, it is essential to consider lifestyle factors that can influence your eye health. Regular breaks during prolonged near work (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds) can help reduce eye strain. Furthermore, maintaining a balanced diet rich in vitamins A, C, and E, along with omega-3 fatty acids, can support overall eye health.

If you are concerned about the progression of your myopia or the management of your astigmatism, it may be beneficial to discuss options such as orthokeratology (corneal reshaping lenses) or myopia control strategies with your eye care professional. Regular follow-ups will help you stay informed about your eye health and any necessary adjustments to your prescription.
