An ophthalmologist in Taipei urged people to adopt good eye health habits as people are developing presbyopia at a younger age.
Tri-Service General Hospital ophthalmologist Lu Da-wen (呂大文) cited the case of a 36-year-old software engineer who consulted him because of blurry vision.
Lu said the patient spent more than eight hours on the computer at work every day and continued to use or play games on the phone after work.

An eye examination found that while the patient’s myopia, or nearsightedness, had improved from about minus-5.00 diopters to minus-4.00 diopters, the patient also had a case of early onset of presbyopia, or longsightedness, the doctor said.
The eyes are like camera lenses in that they automatically adjust the crystalline lenses to focus, he said.
When a person looks at a distant object, the ciliary muscle relaxes to make the crystalline lenses thinner, and when a person looks at an object close by, the muscle contracts, he said.
If a person spends extended periods looking at objects nearby, such as a computer or a phone, then their ciliary muscle will constantly be in a state of contraction, leading to muscle fatigue, the doctor said.
The loss of elasticity of the ciliary muscle is the main cause of presbyopia.
Typically, the ciliary muscle gradually loses its elasticity and ability to focus as a person ages, causing near objects to become blurry and more difficult to see, Lu said.
Presbyopia normally occurs after the age of 40, but because of poor eyecare habits, the condition is affecting people at an earlier age, he said.
Lu said he has seen an increasing number of young people with presbyopia, with the average age dropping to 30-plus.
To prevent eye fatigue, people should keep a distance of more than 40cm while reading and about 70cm when using the computer, he said.
The screens of electronic devices should not be brighter than their surroundings, and users should try to reduce screen glare, he said.
The most important thing is to rest the eyes for 10 minutes for every 30 minutes spent looking at close objects, the ophthalmologist said.
Lu said he understands that this might be difficult for many people because of the nature of their jobs.
If their time does not permit them to do so, they could also use eye drops that relax the ciliary muscle, he said.

Scooter riders should regularly clean their helmets, especially in summer, to prevent dirt and sweat from accumulating and causing scalp problems, such as hair loss and permanent baldness, a dermatologist has warned. Poor hygiene practices by helmet wearers often lead to scalp problems, such as bacterial folliculitis, tinea capitis and seborrheic dermatitis, Lu Pei-hsuan (呂佩璇) at Chang Gung Memorial Hospital said on Aug 31. The first step to maintain good scalp care is proper hair washing, as shampoo residues can easily cause dandruff and itchy scalps, while improper scratching will cause inflammation, Lu said. The best way to wash your hair is to
CONFIRMED IN PHILIPPINES: The CECC would conduct contact tracing for the migrant workers to determine if they had come into contact with elderly people or children Six Filipinos tested positive for COVID-19 upon returning home from Taiwan, the Central Epidemic Command Center (CECC) said yesterday as it reported a case of imported COVID-19 infection, bringing the number of confirmed cases in Taiwan to 500. Philippine authorities reported four of the cases through the National IHR Focal Point, while the other two were reported by the company that they had worked for in Taiwan. The six — five women and one man — are aged from their 20s to 40s, and worked as in-home care workers, domestic workers, factory workers and sailors in Taiwan, said Minister of Health and
INTIMIDATION: Chinese military maneuvers have mostly led to heightened support for Taiwan’s defense forces, while China appears poised to continue its campaign China’s incessant military activities in and near the Taiwan Strait over the past several months are “greater in meaning than in substance,” and are aimed at polarizing Taiwanese society, a researcher said in a report published on Friday. China has attempted to intimidate Taiwan through military threats, while at the same time calling on Taiwanese and US officials to practice restraint, which is aimed at causing a rift between those who prefer resistance against China and those who prefer peace, said Lee Kuan-cheng (李冠成), a researcher at the Institute for National Defense and Security Research. “China’s goal is to obscure public awareness
