Parents are often advised to encourage their children to engage in activities involving far vision.
However, many fail to grasp the significant positive impact far vision can have, especially concerning myopia. Let's delve deeper into why far vision is beneficial in alleviating visual fatigue and promoting overall eye health.
Extended periods of close-range eye use can lead to tension in the ciliary muscles within the eye. Far vision helps relax these muscles. After viewing distant objects, the ciliary muscles relax, facilitating better adjustment.
Should glasses be worn for far vision in individuals with myopia?
Yes, it's better to wear glasses for far vision.
When viewing distant objects with myopia, clear vision is essential. Without glasses, distant objects appear blurred, prompting the brain to strain the eyes to focus, exacerbating eye strain and potentially worsening myopia. Therefore, wearing glasses for far vision is necessary to prevent eye fatigue and further myopia progression.
How far should one gaze?
Ideally, focusing on an object approximately 5 meters away is optimal. At this distance, the eye muscles completely relax.
How often should far vision breaks be taken?
Taking a far vision break every 30-40 minutes of near-range eye use is recommended. This interval can be shortened to around 20-30 minutes for children. Taking breaks to gaze in the distance or engage in outdoor activities can alleviate visual fatigue.
Training methods:
1. Fingerprint-far vision method:
Alternate between looking at a fingerprint for 2 seconds and focusing on a distant object for 5 seconds, repeated for 15-20 minutes multiple times a day. This method also improves visual acuity. Alternatively, use window edges or screens for the same purpose.
2. Develop a habit of looking into the distance
while walking or riding public transportation.
3. Take a 3-5 minute break to gaze into the distance every 30 minutes of work or study. While this helps alleviate fatigue, it may not completely offset negative effects. Increasing the duration of far vision breaks based on individual schedules is advisable.
We can effectively alleviate eye fatigue, promote visual adjustment, and prevent myopia progression through far vision practices. Therefore, both children and adults should cultivate the habit of far vision in their daily lives. By adopting appropriate methods and frequencies, we can provide our eyes with adequate rest and exercise, thus safeguarding visual health and enhancing overall quality of life.
Encouraging a proactive approach to eye care can lead to long-term benefits for individuals of all ages. Developing an awareness of the importance of far vision in maintaining eye health can positively impact individuals' daily routines and contribute to a better quality of life.
