Myopia, also called near-sightedness, is a condition in which close objects appear clearly, but far ones don’t. Near-sightedness tends to run in families and it is the most common cause of impaired vision in people under age 40. In recent years, its prevalence is growing at an alarming rate. Reports suggest that by the year 2050, about half of the world’s population will have myopia.
People who are nearsighted, will have difficulty reading road signs and seeing distant objects clearly, but will be able to see well for close-up tasks such as reading and computer use.
What Causes Myopia?
Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on the retina. The eye condition can also occur when the cornea and/or lens are too curved for the length of the eyeball. In some cases, myopia occurs due to a combination of these factors.
Sometimes, nearsightedness is hereditary. That means you can be at risk of developing myopia if someone else in your family (mother, father, or sibling) is near sighted.
Signs and Symptoms
These signs and symptoms may suggest that something is going on inside your eyes. Your Optometrist will need to diagnose further by conducting several eye tests to determine whether myopia may be setting in or it’s another different eye condition.
Watch out for signs and symptoms of eye diseases such as :
- Eye Strain.
- Feeling fatigue when driving or playing sports.
- Large eyeballs.
- Large cornea
If you experience these signs or symptoms while wearing your glasses or contact lenses, schedule an eye exam with your Optometrist to see if you need a stronger prescription.
Helpful Management Tips
Myopia can be easily diagnosed using standard eye exams given by an eye doctor. It can be managed by wearing a concave or minus Spectacle Lenses, or Contact Lenses depending on which one you prefer. Additionally, a refractive surgery can also be done to correct nearsightedness.
Depending on the degree of your myopia, you may need to wear your glasses or contact lenses all the time or only when you need very clear distance vision, like when driving, seeing a chalkboard or watching a movie. Also, consider photochromic lenses to protect your eyes from UV rays and high-energy blue light and to reduce the need for a separate pair of prescription sunglasses outdoors.
Myopia typically begins in childhood, and you may have a higher risk if your parents are nearsighted. In most cases, nearsightedness stabilizes in early adulthood but sometimes it continues to progress with age. Because some types of myopia can increase with increase in age, while others remain the same throughout an individual’s lifetime, it is therefore very important that you visit your eye doctor regularly to know the type you have.
