Changes in Pupil Size When Looking at Lights

When looking at a light source, one may notice that the halo appears to enlarge and then shrink, sometimes causing confusion. In fact, this phenomenon can be a normal physiological response or it may be caused by factors such as eye strain. Appropriate measures can be taken to effectively alleviate this situation based on different causes.

1. Normal Phenomenon

When the ambient light is dim, the pupil naturally dilates to allow more light to enter the eye. This is a normal physiological response and does not require special concern. To maintain eye health, it is recommended to develop good lifestyle habits in daily life, such as avoiding excessive eye use and staying up late.

2. Eye Strain

Prolonged close use of electronic devices or reading books can cause excessive tension in the eye muscles, leading to abnormal function of the ciliary muscle and resulting in changes in the halo. In this case, appropriate eye massages can be used to relax the eye muscles. Using some eyedrops as prescribed by a doctor, such as Sodium Hyaluronate Eyedrops or Diclofenac and Brucine Eyedrops, can also help relieve discomfort.

3. Refractive Errors

This may be related to genetics or poor lifestyle habits, often accompanied by symptoms such as decreased vision and dizziness. It is recommended to visit the ophthalmology department of a hospital for a detailed examination and receive targeted treatment after identifying the cause. If caused by myopia, it can be corrected by wearing glasses; for hyperopia, convex lenses are required.

Apart from the above reasons, changes in the halo may also be manifestations of ophthalmic diseases such as glaucoma and cataracts. If symptoms are noticeable or persistent, it is recommended to seek medical attention as soon as possible for timely diagnosis and treatment. By understanding these possible causes and corresponding treatments, we can better protect our eye health. When abnormalities in the eyes are noticed, it is important not to ignore them and to take timely measures. I hope everyone can have healthy and bright eyes!
