Common Eye Issues: Symptoms and When to Seek Help

Regarding eye issues?

Next week, I will be going to the military.
Although the eye examination indicated that there were no issues with my eyes, I feel that there might be some problems, and I would like to inquire about them.
Here are the issues I am currently experiencing with my eyes:
1.
I am nearsighted, with approximately 500 degrees of myopia in each eye.
2.
I have floaters; there are several black lines in my field of vision that follow my gaze, and sometimes I also see many flashing black dots.
3.
Around the age of 10, I experienced double vision when looking at nearby objects, while distant objects appeared double as well; sometimes, when I daydream, objects also appear double.
Covering one eye eliminates the double vision.
Is this binocular diplopia? It was not detected during last year's examination.
If it is, can diplopia be temporarily corrected with glasses like myopia?
4.
When looking at streetlights or LED lights, there is a noticeable halo around the light source.
5.
When viewing white light, I see a blue hue in one direction near the white light.
I also notice this with other colors, such as yellow and green, but the blue hue with white light is the most prominent.
6.
When focusing on a chart or a box, the lines appear to slightly waver, but it is not very pronounced; it just moves a little.
Given these points, could there be a possibility of macular degeneration?
7.
Recently, I have noticed that upon waking up in the morning, my eyes feel a bit painful, and I see a dark area in my vision, resembling a net.
However, after blinking a few times, it returns to normal.
Could this be a sign of any condition?
8.
Other potential eye-related issues: I was hit on the head by a rock the size of a palm when I was 8 years old, I sometimes feel a foreign body sensation in my eyes, my eyes occasionally hurt, and I occasionally experience nausea and dizziness (although I believe this is due to irregular sleep patterns).

More Info

It sounds like you are experiencing a variety of eye-related issues that are causing you concern, especially with your upcoming military service. Let's break down your symptoms and discuss what they might indicate, as well as when you should seek further help.

1. Myopia (Nearsightedness): You mentioned having approximately 500 degrees of myopia in both eyes. This is a common refractive error where distant objects appear blurry while close objects can be seen clearly. Regular eye exams and appropriate corrective lenses (glasses or contact lenses) are essential to manage this condition. If you haven't had a recent eye exam, it would be wise to schedule one before your military service.

2. Floaters: The presence of floaters, which you describe as black lines or dots that follow your gaze, is also common. They are usually harmless and occur when tiny bits of gel or cells inside the vitreous (the gel-like substance filling the eye) clump together. However, if you notice a sudden increase in floaters or flashes of light, it could indicate a more serious condition like a retinal tear or detachment, and you should seek immediate medical attention.

3. Diplopia (Double Vision): Your description of seeing double when looking at near or far objects could indeed indicate diplopia. This can occur due to issues with the muscles that control eye movement, or it could be neurological. Since you mentioned that covering one eye resolves the issue, it may be related to how your eyes are working together. A thorough examination by an eye specialist is necessary to determine the cause and whether corrective lenses could help.

4. Halos and Color Distortion: Seeing halos around lights or experiencing color distortions, such as seeing blue light around white light, can be symptoms of several conditions, including cataracts or corneal issues. These symptoms warrant a detailed examination to rule out any underlying problems.

5. Visual Distortion: The slight distortion you notice when looking at lines or borders may be related to how your brain processes visual information. This could be benign, but if it worsens or is accompanied by other symptoms, it should be evaluated.

6. Morning Eye Pain and Temporary Vision Changes: Waking up with eye pain and temporary vision disturbances could be related to dry eyes, eye strain, or even a condition like ocular migraines. If this is a recurring issue, it would be beneficial to discuss it with an eye care professional.

7. History of Eye Trauma: Given your history of head trauma at a young age, it’s important to mention this to your eye doctor. Past injuries can sometimes lead to long-term effects on vision that may not be immediately apparent.

8. Other Symptoms: The occasional feelings of nausea and dizziness could be related to eye strain, especially if you spend long periods focusing on screens or reading. However, if these symptoms persist, they should not be ignored.

Recommendations:
- Schedule an Eye Exam: Given the variety of symptoms you are experiencing, it is crucial to have a comprehensive eye examination by an ophthalmologist. They can perform tests to assess your vision, eye health, and any potential underlying conditions.

- Document Your Symptoms: When you visit the doctor, be prepared to describe your symptoms in detail, including when they occur, their frequency, and any triggers you may have noticed. This information will help the doctor make a more accurate diagnosis.

- Follow-Up: If you receive a diagnosis or treatment plan, ensure you follow up as recommended. Eye health can change, and regular check-ups are important, especially with your military service approaching.

- Protect Your Eyes: In the meantime, practice good eye hygiene. Take breaks from screens, use artificial tears if you experience dryness, and wear sunglasses to protect against UV light.

In summary, while some of your symptoms may be benign, others could indicate more serious conditions that require attention. Seeking a thorough evaluation from an eye care professional is the best course of action to ensure your eye health and address any concerns before you begin your military service.

The symptoms of glaucoma you mentioned likely refer to acute glaucoma, which is almost impossible to occur in eyes with a refractive error of -775 diopters. If the doctor has examined and found no issues, there is no need to worry.
