Why does my left eye sometimes turn inward and blur vision?

Question

Hello doctor,

I have been experiencing a few issues with my eyes and wanted to get your opinion. Occasionally, my left eye seems to turn slightly inward; it is not constant, but I have noticed it happens from time to time. I also experience blurred vision, especially when I have been reading for a long period. Along with that, I sometimes get mild eye strain and headaches.

For context, I am 20 years old, male, around 150 cm tall, and weigh about 88.2 pounds. I am not currently taking any medications.

I would appreciate your guidance on what might be causing these symptoms and whether I should consider getting an eye exam or any specific tests.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

Thank you for sharing. I understand your concern.

Based on your description, it sounds like you may be experiencing intermittent strabismus (a slight inward turning of the eye), along with eye strain and blurred vision during prolonged near work, such as reading. These symptoms can sometimes be linked to uncorrected refractive errors (such as the need for glasses), an imbalance in the eye muscles, or issues with how the eyes work together, like convergence insufficiency or excess.

The headaches and discomfort you are noticing are quite common when the eyes are not coordinating efficiently during tasks that require sustained focus, such as reading or screen use.

Here are my suggestions:

Comprehensive eye examination: Including refraction (to assess whether glasses are needed) and a detailed squint evaluation.
Orthoptic assessment: To evaluate how well your eye muscles are working together and to assess your near focusing ability.

Depending on the results, the following treatments may be recommended:

Prescription glasses, if necessary.
Eye exercises to improve coordination and focusing.
In some cases, prisms or other interventions might be helpful.

Additionally, practicing good visual habits such as taking regular breaks from near tasks, ensuring proper lighting, and maintaining good posture can significantly reduce eye strain.

At this point, there is nothing that appears concerning, but I do recommend scheduling an eye exam soon to identify the underlying cause and determine the most appropriate course of treatment.

I hope this helps.

Kindly revert if there are any queries.

Thank you.
