Do I Need Glasses? Vision Changes and Eye Health - Ophthalmology

More Info

---

Hello! It sounds like you're experiencing some significant changes in your vision, and it's understandable to be concerned about your eye health. Based on your description, it seems that you may indeed need glasses, especially since you're having difficulty seeing the television clearly and struggling to read the blackboard at school without squinting.

When we talk about vision changes, several factors can contribute to the need for corrective lenses. The fact that your vision was previously measured at 0.7 (which is approximately 20/30 vision) and now you're having trouble seeing clearly suggests that your eyesight may have deteriorated. Squinting is often a natural response to try to improve focus when the eyes are struggling to see clearly. This can indicate that your eyes are not able to focus light correctly on the retina, which is where glasses can help.

Here are some points to consider regarding your situation:
1. Regular Eye Exams: It's essential to have regular eye examinations, especially if you're noticing changes in your vision. An optometrist or ophthalmologist can perform a comprehensive eye exam to determine your current prescription and assess your overall eye health.

2. Signs You May Need Glasses: Difficulty seeing at a distance, such as watching television or reading the blackboard, is a common sign that you might need glasses. Other signs include frequent headaches, eye strain, and squinting to see better.

3. Types of Glasses: If you are diagnosed with a refractive error (like myopia, hyperopia, or astigmatism), your eye care professional will prescribe glasses that can help correct your vision. There are also options for single vision lenses, bifocals, or progressive lenses, depending on your specific needs.

4. Impact of Screen Time: If you spend a lot of time in front of screens (computers, tablets, smartphones), this can contribute to eye strain and discomfort. It's important to follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This can help reduce eye fatigue.

5. Eye Health Maintenance: In addition to wearing glasses if prescribed, maintaining good eye health is crucial. This includes protecting your eyes from UV light with sunglasses, eating a balanced diet rich in vitamins A, C, and E, and staying hydrated.

6. Consultation with an Eye Care Professional: Given your symptoms, I recommend scheduling an appointment with an eye care professional as soon as possible. They can provide a thorough examination and discuss the best options for your vision needs.

In summary, based on your current difficulties with vision, it is likely that you may need glasses. A professional eye exam will provide you with the necessary information to make informed decisions about your eye health. Don't hesitate to seek help; addressing vision changes early can significantly improve your quality of life and academic performance.
