You have to take good care of your eyes, and that could mean you have to wear glasses. The most common vision problems are nearsightedness (hypermetropia or hyperopia), farsightedness (myopia), astigmatism (astigmatism), and old eye (presbyopia). Many people suffer from vision problems, but they delay going to the optometrist or the ophthalmologist, or don't even go at all. If you feel your vision level is deteriorating, it's best to make an appointment with an ophthalmologist as soon as possible. As with decreased vision, there are other indicators that may require you to wear glasses.
Step
Method 1 of 4: Measuring Near and Far Vision
Step 1. Find out if your near vision is blurry
If near vision appears blurry, it is an indicator of farsightedness. If your eyes can't see objects that are close to focus (sharp), you may have farsightedness. There is no specific blur distance to determine if you are farsighted.
- The severity of nearsightedness will affect your ability to focus on close-up objects. So the farther the eye needs to focus on something, the more likely it is that you are farsighted.
- If you have to sit quite a distance from your computer screen or have to hold a book with your arms outstretched, these are common indicators that you are farsighted.
Step 2. Notice if you find it difficult to read
If you often work with close vision, such as drawing, sewing, writing, or working on a computer, then your vision is no longer in focus, it could be a symptom of presbyopia (old eyes). Presbyopia is a type of farsightedness caused by reduced elasticity of the eye muscles. As you get older, your chances of developing presbyopia increase.
- You can check it by holding the book in front of you and reading it as usual. If your vision can only focus at a distance of more than 25 or 30cm, you most likely have presbyopia.
- If you have to move books away to focus your vision, you may have presbyopia.
- Usually reading glasses can help solve this problem.
- Presbyopia generally affects people between the ages of 40 and 65.
Step 3. Notice if distant objects look blurry
If the farther away an object looks blurry, while the nearer object still looks sharp, you may have nearsightedness. Nearsightedness usually begins around puberty, but it can appear at any age. As with farsightedness, farsightedness does not have a specific blur distance standard to determine it. However, if your eye focus is normal when reading the newspaper, and you have difficulty reading the writing on the blackboard when sitting in the back seat, or you have to sit closer to the television in order to read the writing, you are most likely nearsighted.
- There is evidence that children who spend more time doing near vision-related tasks - such as reading - are more likely to develop nearsightedness.
- However, genetic factors have a more significant influence than environmental factors.
Step 4. Notice if you have trouble seeing objects at near or far distances
Instead of having trouble seeing objects that are near or far, you'll have a hard time focusing on both. If you experience this, chances are you have astigmatism.
Method 2 of 4: Pay attention to whether your eyes are blurry, squinting, sore, and sore
Step 1. Notice if your vision is blurry
If you experience moments when your vision becomes blurry, don't take it lightly. That could be an indicator of a broader health problem, and you should see a doctor immediately. If your vision is occasionally blurry or only one eye is blurry, see an optometrist or ophthalmologist.
- Blurred vision indicates a lack of sharpness and fine detail when you are looking at something.
- Notice whether this happens when you are looking at a near object, a far object, or both.
Step 2. Notice if your eyes have to squint to see clearly
If you frequently squint and squint to focus on something so you can see it clearly, it could be a sign that you have eye problems. Pay attention to how often you squint involuntarily and see an eye doctor immediately.
Step 3. Notice if the objects you see appear to be duplicates
Double vision can be caused by a variety of things, from the muscles to the nerves of the eye. However, it can also indicate eye problems that may be corrected simply by wearing glasses. Whatever the cause, double vision should not be taken lightly and consult a doctor immediately.
Step 4. Notice if you have a headache or eye strain
If your eyes hurt or you have frequent headaches, it could be an indicator of an eye problem. Eye strain or headaches after close-up work may indicate presbyopia or farsightedness.
- This condition can only be examined by an optometrist or ophthalmologist, so you should make an appointment.
- An ophthalmologist can prescribe the right glasses for your condition.
Method 3 of 4: Diagnosing the Problem Through the Eye's Response to Light
Step 1. Notice if you have trouble seeing in the dark
If you have trouble seeing especially at night, this could indicate an eye problem. Poor night vision can be a symptom of cataracts. So if you notice a significant difference in your night vision, see an eye doctor immediately.
- Maybe you're having trouble driving at night or you can't see things in the dark that others can still see.
- Other indicators include difficulty seeing stars at night or moving around in a dark room, such as in a movie theater.
Step 2. See if you have trouble adapting your eyes from light to dark environments
The time it takes to adapt to changes in light and dark generally increases with age. However, if you find this adaptation increasingly difficult, it could be a sign that you have eye problems and need glasses or contact lenses. However, it can also be associated with other common medical conditions.
Step 3. Notice if you see a halo around the light
If you notice halos appear around light sources such as light bulbs, you may have a problem with your eyes. Halos are a common symptom of cataracts, but they can also indicate one of the four main eye problems. Make an appointment with an eye doctor to diagnose it.
Step 4. Notice if your eye's sensitivity to light is increasing
If you experience a significant increase in sensitivity to light, see an eye doctor immediately. This condition can indicate a number of eye problems. So you should see a specialist to get a complete diagnosis. If these changes are sudden and dramatic, don't hesitate to contact your doctor immediately.
If light hurts your eyes or you have to squint or squint in bright light, your eye sensitivity is increased
Method 4 of 4: Checking Vision at Home
Step 1. Use printable eye test material
If you experience the above symptoms, do not delay, contact an eye doctor immediately for examination. However, you can also do basic tests at home to measure vision. Print a classic test page from the internet containing an eye test in ever smaller letters.
- After printing it, hang it at eye level in a bright room.
- Stand 3 meters away and see how many letters you can read.
- Continue until the row of letters is at the bottom or bottom you can read. Write down what line of numbers you can read most of the letters in.
- Do it again, this time closing one eye each time you do the test.
- Results will vary depending on age. However, older children as well as adults should be able to read most of the letters in the bottom twentieth row.
Step 2. Try a test on the internet
In addition to the test sheets that can be printed, there are several types of tests that you can do directly on the computer. Again, this test is not perfect, but it can provide basic indications of eye conditions. You can find different types of tests for different eye problems, including color blindness and astigmatism.
- In this test, you will see different pictures and shapes on a computer screen. Follow the instructions to test your eye.
- Please note, these tests are only sketchy guidelines and should not be treated as substitutes for actual tests.
Step 3. See an eye doctor
Do not forget, if you experience the above symptoms, immediately contact an eye specialist and have a thorough examination. Your optometrist or ophthalmologist will give you a number of tests to find out the root cause of your eye disease. And if you need glasses, they will give you a prescription. At first this examination may feel intimidating or a little scary, but you certainly need to take good care of your eyes.
- The ophthalmologist will use a number of instruments, shine a kind of bright flashlight into your eye, and ask you to wear a number of lenses of different sizes.
- You must read the letters from the test board while wearing the different lenses.
- Optometrists and ophthalmologists alike can perform eye evaluations.
Step 4. Know the next steps you should take if you need glasses
After the examination, the doctor will tell you whether you need glasses or not. If so, you will be given a prescription. Take the prescription to an eyewear store and choose the frame you want. Optometrists are trained to match glasses to your needs.
After choosing the frame, you will have to wait a few days to a week for the glasses to be ready
Tips
- Don't lie if you can't see the letters on the test board because if you don't wear glasses when you need them, your eyes can get worse.
- If you must wear glasses, make sure you know how and when to wear them. Ask an optometrist for more detailed information.
- Print or draw an eye chart and ask someone to help you do a vision test and tell you the results.
Warning
- If you are buying new glasses, make sure the lenses don't reflect the sun's rays as they can damage your eyes.
- Remember, you don't have to wear glasses all day and night. You may only need reading glasses, but this will be explained in more detail by an optometrist.
- There is also another option, namely contact lenses, if you dare touch your eyes to put them on and take them off.
