Myopia (or nearsightedness) is very common. One out of two people (50%) has it. With myopia, the eye is longer than normal from front to back, or the cornea (the clear window at the front of the eye) is too steeply curved. This makes things that are far away from you look blurry. Myopia is corrected with glasses, contact lenses or surgery in some cases. Having myopia can increase your chances of having some eye problems later, like cataract, glaucoma, and retinal detachment.
Studies show myopia is becoming more common among children. While there is no proven direct link, research suggests that children who spend more time indoors doing near-focused activities (such as computer work, video games, and reading) have higher rates of myopia than those who spend more time outdoors.
Doctors are looking at ways to slow the progression of myopia in children. While myopia cannot be reversed, the goal of treatment is to keep it from getting worse. This can protect a child’s eye health in the future, despite still needing to wear glasses or contact lenses.
There is no best method for correcting myopia. The most appropriate correction for you depends on your eyes and your lifestyle. Discuss your lifestyle with your ophthalmologist. Together, you can decide which correction may be most effective for you.
Eyeglasses or contact lenses are the most common methods of correcting myopia symptoms. They work by refocusing light rays on the retina, compensating for the shape of your eye. Eyeglasses can also help protect your eyes from harmful ultraviolet (UV) light rays. A special lens coating that screens out UV light is available.
MiSight (Coopervision) is a daily disposable contact lens that gives clear vision while slowing down myopia progression. They are worn like any regular daily disposable contact lens, and are disposed of at the end of the day. As with regular soft contact lenses, there is a very low chance of bacterial infection, which is mitigated with proper hygiene and lens wear schedule.
MyoVision (ZEISS) is a specialized type of lenses that is designed to slow down myopia progression. They work similar in concept to MiSight Contact Lenses.
In many cases, people may choose to correct myopia with LASIK or another form of refractive surgery. These surgical procedures improve your vision by reshaping the cornea. The reshaped cornea focuses light properly onto the retina.
Refractive surgeries for myopia include:
