Vision and its quality play an integral role in how we perceive the world around us. Except while sleeping, our eyesight is involved in almost every activity we carry out. It wouldn’t be wrong to say that having a correct vision is indispensable in leading a life of quality.
It has been estimated that more than 250 million people suffer from some form of visual impairment. Undiagnosed and untreated refractive errors like short-sightedness, far-sightedness, and astigmatism are responsible for more than 50% of visual impairment.
Meaning Of 20/20 Or Normal Vision
On getting your vision tested, your optometrist or ophthalmologist will note down your eyesight on the prescription. If it’s 20/20, you should be glad that you have normal vision with adequate clarity and sharpness. This reading was taken when you were asked to read the Snellen’s chart at a distance of 20 feet. It also indicates that the visual acuity you have while standing 20 feet away from an object is what most people with normal vision has at the same distance.1
Significance Of 20/30 Vision In Adults
Simply put, having 20/30 vision means, you would need to be 20 feet away from an object to view it clearly which a person with normal vision could’ve viewed at 30 feet itself.2
Don’t get rattled by these fractions as you are not the only one with impaired eyesight in the world. Scientific studies claim that only 35 percent of all adults have perfectly normal 20/20 vision without any correction. 75 % of them can see better provided they use a corrective measure like glasses, contact lenses or surgery. However, 25 percent find it hard to see with good visual acuity despite correction.
If you have 20/30 vision but can still see everything clearly while doing day-to-day activities, you can give glasses a pass. But, if you develop eye strain and headaches frequently, you should meet an eye specialist and get contact lenses or glasses.
20/30 Vision In Children
Babies are born with absolutely imperfect vision. They are usually farsighted and don’t develop the ability to see distant objects clearly until they turn a year old. By the time your toddler is 3 years old, her vision should be at least 20/40. At around age 5, her vision will be at 20/30.
Most ophthalmologists may hold off glasses until your child is at least 7 or 8 if they feel that the vision can be self-corrected by the eyes. However, if your child’s vision doesn’t seem to improve even after 7 years of age, she would need glasses.3
Ways To Prevent Vision-Related Problems
Following certain mindful practices to nourish your eyes from within can prevent the development of any vision problems to a large extent.
- Have a diet rich in carotenoids. These can be found majorly in leafy greens, colored fruits, and vegetables. Children should be encouraged to eat these foods right from a young age.
- Exposure to television, mobile phones and computers should be not more than an hour for kids. Adults too should cut back on excessive screen time to avoid eye strain.
- Watch the telly at a distance of 9 feet within a well-lit room.
- Making time for outdoor play or any fitness activity should be strictly followed.
- People of all ages should wear protective gear should while swimming or indulging in active sports.
Vist the ophthalmologist at least once a year to keep a tab on your eyesight. Refractive errors can be rectified by using specific corrective measures if detected at the earliest. In the absence of enough visual acuity, you are missing out on enjoying life in all its loveliness!
