Eye Focus Issues: Near Vision Problems Explained - Ophthalmology

Understanding eye focus issues, particularly when it comes to near vision problems, can be quite complex. Your description indicates that you have difficulty focusing on objects at a medium distance, while your far and near vision seem to be functioning adequately. This situation can arise from several underlying causes, and it is essential to understand these to address your concerns effectively.

Firstly, the inability to focus on objects at a medium distance could be related to a condition known as accommodative dysfunction. The eye's ability to focus on objects at varying distances is primarily managed by the ciliary muscle, which adjusts the lens's shape. If this muscle is fatigued or not functioning optimally, it can lead to difficulties in focusing, particularly at intermediate distances. This is often exacerbated by prolonged near work, such as reading or using a computer, which can lead to eye strain and fatigue.

Additionally, your mention of experiencing "jumping" or oscillating vision when using both eyes could suggest a condition known as convergence insufficiency. This occurs when the eyes do not work together effectively while focusing on a near object, leading to symptoms such as double vision, blurred vision, or the sensation that the eyes are not aligned properly. This condition can be particularly common among individuals who have a significant difference in prescription between their two eyes, as in your case.

The phenomenon of seeing light circles or halos when your eyes are closed at night can be related to several factors, including dry eyes or even a form of visual disturbance known as entoptic phenomena. These light patterns can occur due to the way light interacts with the structures within your eye, particularly if there is any irregularity in the cornea or lens.

Given your current prescription of -6.25 in the left eye and -7.25 in the right eye, it is important to consider that high myopia (nearsightedness) can lead to various complications, including retinal issues or changes in the eye's structure that may affect vision. Regular eye examinations are crucial for monitoring these changes, especially since you are experiencing new symptoms.

In terms of management, it is advisable to schedule an appointment with an eye care professional for a comprehensive eye examination. They can assess your visual acuity, check for any underlying conditions, and determine whether your current prescription is still appropriate. They may also evaluate your eye coordination and focusing abilities to identify any specific issues that may be contributing to your symptoms.

In the meantime, consider implementing some strategies to alleviate eye strain. The 20-20-20 rule is a helpful guideline: every 20 minutes, take a 20-second break to look at something 20 feet away. This practice can help reduce fatigue on the ciliary muscle and improve your overall comfort while using your eyes.

In summary, your difficulties with focusing at medium distances, the sensation of jumping vision, and the light circles you observe warrant further investigation. These symptoms could be linked to accommodative dysfunction, convergence insufficiency, or other underlying conditions related to your myopia. Regular eye examinations and appropriate management strategies will be essential in addressing these issues and maintaining your eye health.
