What Is Myopia?
Myopia, also known as nearsightedness, is a common vision problem that will affect half the world’s population by 2050. It occurs when the eye is unable to focus on distant objects without corrective lenses like glasses or contacts. Myopia is caused by a variety of factors, including genetic and environmental factors, and tends to worsen with age.
To understand how myopia develops, knowing how your eyes work together with the rest of the body to see is helpful. The eye has two main parts: the sclera, which is the outer layer, and the retina, which is the inner layer. The cornea, a clear dome that covers most of the front part of the eye, helps protect the eye from dust and germs. Light enters through the cornea and is converted into electric signals by the rods and cones in the retina. These signals are sent to the brain through optic nerve fibers, where they are interpreted as the images, we see every day.
Is Myopia Genetic?
If you're thinking about myopia, knowing if it's genetic is essential. If you happen to be myopic, then your kids might be at risk of developing the same condition.
Myopia has two types: genetic and non-genetic (or "acquired"). Genetic myopia is passed down through families and tends to run in certain clusters or patterns. Non-genetic means that individuals develop their vision issues without any family history or a genetic predisposition toward poor vision.
In general, suppose both parents have healthy eyesight but have children with poor vision (without any other eye problems). It's likely that those kids were born with a form of genetic myopia known as Axial Myopia (AM). About half of all cases fall into this category!
Why Does Myopia Get Worse with Age?
There are several reasons why your myopia may get worse as you age. The first and most apparent is that the lens inside your eye becomes thinner with time. This causes it to lose elasticity and become less able to focus correctly on objects at a distance. Another reason for this is that as we age, we start losing corneal tissue due to natural wear and tear. This makes our corneal curvature less steep, affecting our ability to see clearly at long distances.
Another factor contributing to the worsening of nearsightedness is increased pressure inside the eye (IOP) caused by glaucoma or macular degeneration. Increased IOP causes fluid leakage into surrounding tissues, leading to swelling and softening of collagen fibers in the front part of the eye's optical system, resulting in blurred vision or blindness if left untreated.
How to Stop Myopia from Getting Worse with Age
To prevent myopia from getting worse with age, it's important to get regular eye exams, wear glasses when necessary, and avoid activities that can cause eye strain. If you're concerned about your eyesight, it's always a good idea to schedule an appointment with a Treehouse Eyes optometrist.
