Around the World, humans deal with a lot of problems. Whether they are health issues or other issues that life brings us, they can make our lives more difficult to manage.

A study shows that many people deal with eye problems, about 75% of adults use a form of eye correction, and 64% wear glasses.

The answer is simple. Some of us are born with vision problems, but vision problems also occur with advancing age. Usually, the first sign would be blurred vision, and only glasses with certain diopter lenses can improve our eyesight.

Nearsightedness (myopia)

The struggle to see far away is named myopia. People that have myopia see well the objects near them, but objects get blurrier as they move away.

Nearsightedness occurs when the eyeball grows longer than normal for its width, making the focal point of distant objects in front of the retina. It is the most common vision disorder, affecting up to two-thirds of Americans at some time during their lives.

This is how you realize that you should go to the doctor for further investigations. Myopia is corrected with special divergent lenses, that make the eye see well but they sadly don’t make the eyes better. Over the years, diopters get bigger and there is nothing to do about it. Usually, myopia is a hereditary disease and you need to wear glasses all the time.

The American Association for Pediatric Ophthalmology and Strabismus recommends that parents take their children to an eye doctor if they have difficulty seeing the board when sitting in the back of their classroom and/or have issues with schoolwork involving reading text on a blackboard.

Nearsightedness (myopia) usually starts around age 8 and gets worse as a person gets older.

Farsightedness (hyperopia)

The opposite of myopia is hyperopia. The problems hyperopia makes are felt when reading something that is close to us. The image is focused behind the retina, so converging lenses are the solution.

As the years go by, adults that reach 40-45 years are starting to have close-reading issues. If your vision is good and you struggle to see only when you read something tiny or when you knit, then you need to wear glasses that enlarge the image only when you do these things.

Specialists warn us to be careful and not to wear this type of glasses all the time.

Astigmatism

Astigmatism is a condition where the front surface of the eye, called the cornea (the clear front part of the eye), is shaped irregularly.

This causes light to focus in two places on the retina instead of one, resulting in blurred vision. In some cases, astigmatism cannot be corrected and must be managed with glasses and contact lenses. Astigmatism can be corrected with glasses, contact lenses, or surgery (usually LASIK in most cases).

It may cause eyestrain, headaches, and difficulty doing close-up tasks such as reading.

If it’s not treated right, the following symptoms may be felt: eye fatigue, tiredness, and overall feeling weak.

The eye specialist can also prescribe vitamins that help the eye’s tiredness and dryness.

Presbyopia

Presbyopia is a condition that occurs when the natural focusing ability of your eyes declines with age. This results in blurred vision and poor distance vision, especially reading vision.

It is the name given to a vision condition affecting the lens of the eye. The lens, which focuses light on the retina to allow clear vision, becomes less elastic or flexible with age, this makes it harder for light to pass through and focus on the retina, causing difficulty in focusing close up and/or even.

What Kind of Glasses Will I Need?

Depending on the vision problem you have, an eye specialist will determine which lens is best for you.

Myopia: A concave lens (curves inward).

Farsightedness: A convex lens (curves outwards).

Astigmatism: A cylinder-shaped lens.

Presbyopia: Bifocal or multifocal lens.

Choosing the right form of glasses is also an important part. Always try more types of frames that suit well your face shape.

Oval Face Shape: Proportionally balanced faces look good with any type of glasses frame. See models on Amazon.

Square Face Shape: Round and oval glasses add balance to square faces.

Diamond Face Shape: Round, oval, and cat-eye styles fits well.

Round Face Shape: Rectangle and geometric frames.

Symptoms That Indicate the Need to Wear Glasses

  • Distance vision difficulties
  • Double Vision
  • Squinting to See Clearly
  • Frequent Headaches
  • Reading difficulties
  • Dizziness
  • Reddening of the eyes and a stinging sensation
  • Watery eyes

Take Care Of Your Health

You only have one life, so take care of your body’s health to extend your lifespan and a state of wellbeing. If you have chosen to take care of your health, here are some tips that will help you.

Eat Healthy Foods

Salmon, soybeans, carrots, sweet potatoes, eggs, or walnuts can improve your vision. Studies show that vitamin A intake can reduce the risk of AMD ( age-related macular degeneration). Be aware that the recommended daily allowance for vitamin A is 700 mcg a day for men and 600 mcg a day for women.

It is proven by some studies that Omega 3 consumption has benefits for people who have dry eyes. You can get your omega-3s by eating flax seeds, fatty fish, algae, or walnuts. Another way to get your omega-3s is to take supplements but not exceed the daily dose of 250-500 mg recommended by specialists.

Get Active

Staying physically active lowers your risk of health conditions that cause vision problems such as high blood pressure, diabetes, or high cholesterol.

Specialists recommend a minimum of 30 minutes of moderate activity per day. Try also to reduce sitting time, if you work at a desk, give yourself 2 minutes for a short walk or light exercise to relax.

Quit Smoking

If you smoke, you are twice as likely to develop AMD (age-related macular degeneration) and 2 to 3 times more likely to develop cataracts than a non-smoker. These are just the eye-related consequences, smoking is very harmful.

Tips for Eye Health

Give your eyes a rest. With the 20-20-20 rule, you can get rid of eye strain, a real problem that affects a lot of people nowadays. If you work in front of a screen for a long period of time within a day, every 20 minutes, look at something 20 feet (6 meters) away for 20 seconds.

What Vision Problems Can Eyeglasses Correct?

You may need glasses for problems such as:

  • Nearsightedness (myopia): You see close objects clearly, but objects farther away look blurry.
  • Farsightedness (hyperopia): Objects in the distance look clear, while things close by look blurry.
  • Astigmatism: A problem with the shape of your cornea (or lens) that causes blurry or distorted vision.
  • Presbyopia: Your eyes lose the ability to focus on nearby objects (an age-related condition).

Advantages of Eyeglasses

The best thing about eyeglasses is that they improve vision, making it easier for you to see your target item.

Additionally, wearing eyeglasses can help you feel less self-conscious about your appearance and image, as many people will tend to regard you more positively when they see that you are wearing glasses.
