Is myopia a disease that is passed down from one generation to the next? Learn from an expert
The problem of myopia has increased significantly these days. Myopia is a common eye problem that can have many causes. This raises the question of whether genetics is a major cause, meaning can this disease be passed down from one generation to the next? Let's find out.
Myopia is a condition in which a person can see nearby objects clearly, but distant objects appear blurry. This problem occurs when the eye is enlarged or the cornea is excessively curved.
This causes light to not focus properly on the retina, and distant objects appear blurry. Myopia is becoming increasingly common worldwide, especially among children and teenagers. In many countries, 40-50% of children are affected by some degree of myopia.
There are two main types of myopia : simple myopia and high myopia. Simple myopia progresses slowly and can be easily controlled with glasses, while high myopia progresses rapidly and carries a higher risk of retinal problems. Symptoms include blurred vision, eye strain, frequent blinking, headaches, and squinting while reading.
Is myopia a disease that is passed on from one generation to another?
Myopia is a rapidly increasing problem among children today. It's important to understand that it's not just a genetic condition; lifestyle factors are just as important.
Dr. Sapna Chanana (MBBS, MS) of Avience Eye Care, Delhi, explains that if one or both parents are myopic, a child's risk of developing myopia increases significantly.
However, in today's world, children's prolonged exposure to screens, limited outdoor time, poor reading postures, and extreme close-up viewing exacerbate this problem.
Children's eyes are still developing, so constant exposure to screens puts strain on the eye muscles and gradually weakens their distance vision. However, the progression of myopia can be largely controlled by good habits.
Spending 12 hours outdoors daily, playing in natural light, following the 20-20-20 rule while studying, and keeping books and screens 30-40 cm apart are all extremely beneficial for children's eyes. If there is a family history of myopia, regular eye check-ups are also essential.
Keep these things in mind
- Get outdoor activity done for at least 12 hours every day.
- Limit screen time and follow the 20-20-20 rule.
- Maintain proper distance while studying or watching screen.
- Keep adequate lighting in the room.
- Avoid reading while sitting in the wrong position.
- Get your eyes checked at regular intervals.
- Keep very young children away from mobile phones or tablets.
