Eyesight is an essential part of life. It allows us to see, read, drive, watch TV, play sports, and much more. However, eyesight can deteriorate with age.
If you want to improve your eyesight, there are several ways to do it. In this article, I will tell you how to improve eyesight in 13 easy ways.
What Is Eye Health?
Eye health (Ocular Health) is the state of complete eye function, including vision, ocular surface integrity, tear production, and protection against infection.
The eyes don’t usually hurt when something is wrong. There are a number of eye diseases that have no visual symptoms in the early stages. Eventually, these diseases can cause permanent damage to our eyes.
An eye examination will then be performed to check the internal and external health of your eyes, check for possible diseases, and performs a refractive visual analysis to assess if actions as necessary.
Children need to have regular eye exams to determine if their eyes are developing right. Learning disorders and vision loss can be caused if there is a problem that goes unaddressed.
What Are The Basic Eye Exams
The first step towards improving your eyesight is having an eye exam. This test includes checking your eyes’ ability to focus on objects at different distances, measuring the size of your pupils, looking inside your eyeballs, and testing your eyes’ reaction time.
Here are some of the basic eye exams performed:
- Applanation Tonometry Tonometry measures intraocular pressure by using an applanation tonometer which applies force directly onto the cornea. The measurement is taken from the center of the cornea where the highest resistance is found. In order to measure the correct reading, the examiner needs to make sure that the patient’s head position remains stable during the procedure. If not, the results may vary significantly.
- Corneal Topography A topographer uses a device called a keratoscope or videokeratography machine to create a map of the shape of the front portion of the human cornea. A topographer takes measurements of the curvature of the cornea and creates 3D images showing its contour. These images show any irregularities such as scars, pterygiums, etc. This information helps doctors diagnose problems such as astigmatism, myopia, hypermetropia, presbyopia, dry eye syndrome, glaucoma, etc.
- Fluorescein Angiogram A fluorescein angiogram (FA) is an imaging test that uses a fluorescent dye to help doctors see blood vessels in the eye. FA is used to diagnose problems with the retina, optic nerve, and choroid.
- Dilated Pupillary Exam/ Dilated Eye Exam Dilated pupil exam is an eye examination that involves looking at the pupils of the eyes to check for signs of diseases like glaucoma.
- Refraction Test
A refraction test measures the amount of light entering each lens of your eyes. If one or both lenses become cloudy, they may not allow enough light into your eyes.
- Slit-Lamp Exam Slit-lamp exam is an ophthalmic examination that uses a microscope and special lenses to examine the front part of the eye. This includes the cornea, iris, lens, retina, vitreous humor, and optic nerve.
- Non-Contact Tonometry Non-contact tonometry (NCT) is an ophthalmic technique used for measuring intraocular pressure (IOP). NCT uses a non-invasive method that does not require contact between the eye and any instrumentation.
- Retinal Tomography Retinal tomography is the imaging of the retina using optical coherence tomography (OCT). OCT is an interferometric technique that uses low-coherence light to measure the backscattered intensity of reflected light from within the tissue being imaged.
- Eye Ultrasound An ultrasound device that uses sound waves is used to create an image of the inside of your eye.
- Visual Acuity Testing Visual acuity testing (VAT) is an eye examination that measures visual ability. It can be used to diagnose vision problems and determine how well someone sees.
- Visual Field Test Visual field testing is an eye test used to determine how well your eyes can see in different directions. This test helps doctors diagnose problems like glaucoma and macular degeneration.
What Eye Conditions Can Be Treated with Home Remedies?
We all want clear eyesight. However, there are certain eye conditions that can be treated at home without having to visit an ophthalmologist. These eye conditions include:
Conjunctivitis is inflammation of the mucous membrane lining the inside of the eyelids and the space between the eyeball and the eyelid. It is caused by bacteria, viruses, allergies, or other irritants.
The home remedy for conjunctivitis is to use eye drops. If you do not want to use eye drops, then you should visit your doctor.
Blepharitis is a condition where the eyelids become inflamed and swollen. The cause of blepharitis is usually due to bacteria living in the oil glands of the eyelid. The cause of blepharitis is usually unknown. It can be triggered by allergies, poor hygiene, or wearing of contact lenses.
There are several ways to treat blepharitis. One way is to use eye drops containing antibiotics. Another way is to clean the eyelids using cotton balls soaked in saline solution.
Dry eye syndrome
Dry eye syndrome is a condition where the tears become too thin and evaporate too quickly. Symptoms include burning, itching, irritation, redness, and blurred vision. Dry eye syndrome is often associated with menopause, pregnancy, or hormonal changes.
The best way to treat dry eyes is to use artificial tears. Artificial tears contain glycerin which lubricates the eyes and helps them stay moist. If you don’t have any artificial tears, then you should try using saline solution. Saline solution has the same effect as artificial tears, but it doesn’t cause irritation like artificial tears do.
Keratoconjunctivits sicca (KCS) is an inflammation of the mucous membranes lining the eyes, including the conjunctiva and cornea. This condition can be caused by dryness of the eyes due to a lack of tears, or by a deficiency in tear production.
The home remedy for keratoconjunctivis sicca is eye drops containing artificial tears. Artificial tears help lubricate the eyes and prevent dryness.
Pink eye is an infection of the conjunctiva (the clear lining that covers the white part of the eyeball). It is caused by bacteria in the eyes.
The best way to treat pink eye is to wash your hands frequently with soap and water. If you do not have access to clean running water, then use a hand sanitizer. Do not rub your eyes with your hands.
What Eye Diseases are Preventable With Lifestyle Changes?
What eye Problems Need Medical Attention
Eye problems are common among people of all ages. However, there are certain conditions that require medical attention. These conditions can cause serious damage to your eyesight if left untreated.
Here are some of the most common eye problems that should be taken seriously.
Glaucoma is a disease that damages the optic nerve, which is responsible for transmitting visual information from the eye to the brain. The damage caused by glaucoma leads to vision loss. There are two types of glaucoma: open-angle and closed-angle. Open-angle glaucoma is the most common form of glaucoma. This type of glaucoma occurs when fluid builds up behind the iris of the eye, causing pressure inside the eye to increase. Closed-angle glaucomas occur when the drainage system malfunctions, allowing fluid to build up in the front part of the eye.
Lower eye pressure is one of the ways Glaucoma is treated. Depending on your situation, you can either take prescription eyedrops or take oral medications.
Cataracts are clouded lenses that cause vision loss. The most common form of cataract is age-related, but other factors such as diabetes, high blood pressure, and smoking can also contribute to cataracts.
When your vision is not clear from your glasses, the only effective treatment is surgery.
Poorly controlled blood sugar may cause damage to the blood vessels in the retina. This is called Diabetic Retinopathy. Symptoms may include the following:
- blurry vision
- dark areas of vision
- difficulty perceiving colors.
Diabetes management is the best treatment for mild cases while advanced cases may require laser treatment or surgery. Treatments are offered if diabetic eye screening detects stage three (proliferative) retinopathy.
Macular Degeneration/Age-related macular degeneration (AMD)
Macular Degeneration is a condition where the macula (the part of the retina responsible for sharp central vision) deteriorates. It usually affects older adults over 50 years old. Although it does not affect everyone who has this problem, those at risk are more likely to develop symptoms. Some signs and symptoms of Macular Degeneration include blurred vision, blind spots, difficulty reading, trouble seeing faces, and poor night vision.
There is no cure for Macular Degeneration; however, treatments exist to slow down its progression.
What Eye Problems Require Immediate Attention?
Contact your health care provider if you have the following:
Continuing symptoms of pain
This could be from something that’s been in the eye. Foreign bodies can become lodged in the eye.
If the foreign body is metal, you should go to the emergency room immediately. Iron fragments will rust quickly and this can be difficult to treat. The foreign body and rust need to be removed. The longer it is in the eye, the more difficult it will be to remove all the rust.
Foreign bodies stuck under the eyelid can cause pain or make it feel like a bug in the eye.
There is also pain in angle-closure glaucoma. This is where the internal eye pressure is high and can cause blindness in a short period of time.
A rapid loss of vision in one or both eyes can be caused by a problem with the eye’s retinal structure. The back of the eye is where the visual image is formed. There are many common problems including Retinal hemorrhages, tears, or detachment. These are serious conditions and need us to see a doctor right away. It is important to treat Retinal detachments quickly.
There are warning signs of retinal detachments, which can include flashes of light, increased floaters, and/or a painless loss of peripheral vision.
There are several factors that may cause increased sensitivity to light:
- Corneal abrasions
- Corneal ulcers cause pain and light sensitivity. These are serious and most commonly occur in people who sleep in their contact lenses.
- Ulcer caused by Pseudomonas bacteria
You may have serious problems that need prompt treatment if you have these symptoms. It is possible for a person to lose vision from one of these conditions without treatment.
When to Call Your Doctor
It can be difficult for patients to know if they have a serious condition. If you are unsure, you should call your doctor. If not treated in time, many of these eye problems can rapidly get worse and lead to permanent loss of vision.
How to Improve Eyesight: Here are 16 great tips!
1. Don’t Smoke! Smoking is a major cause of poor vision due to its negative effects on blood circulation. It also damages the retina which can lead to blindness if left untreated.
2. Drink Plenty Of Water! Drinking enough water helps flush toxins from the system and keeps organs functioning properly. The human body needs about 2 liters of fluid per day for proper function.
3. Exercise Daily! Physical activity boosts energy levels and improves overall well-being. Try walking briskly for 30 minutes every morning before breakfast. You can also research and perform eye exercises that will target the muscles around your eyes!
4. Reduce Stress Levels! Too much stress leads to high cortisol levels which may contribute to blurry vision. Relax by taking deep breaths and meditating daily.
5. Wear Sunscreen When Outdoors! Spending time outside without sunscreen exposes us to harmful ultraviolet rays. Use sunblock or UV protection containing zinc oxide or titanium dioxide to reduce the amount of damaging rays reaching the surface of the skin.
6. Maintain Good Nutrition Habits! Eating foods rich in vitamins and minerals like carrots, spinach, broccoli, oranges, tomatoes, beans, whole grains, sweet potatoes, fish, and lean meats can improve vision. Foods high in omega 3 fatty acids have been shown to lower inflammation associated with many chronic conditions including diabetes, heart disease, arthritis, asthma, depression, and Alzheimer’s Disease.
7. Keep An Eye On Medications & Supplements! Many medications and supplements can affect how well your eyes work together. Be sure that what you are using won’t harm your sight. Talk to your doctor if you aren’t sure whether something will be safe for you.
8. Healthy Diet! Eat Healthy Fruits And Veggies rich in vitamin A, vitamin C and vitamin E. Fresh fruits and vegetables contain antioxidants that protect against free radical damage. Antioxidants help keep cells healthy so they don’t become damaged when exposed to UV radiation. They also prevent cell death caused by oxidation. Oxidation occurs naturally as part of normal metabolism but it becomes problematic when we eat too few antioxidant-rich foods.
9. Avoid Alcohol Consumption! Excessive alcohol consumption has been linked to increased rates of cataracts, dry eyes, and other problems affecting the cornea.
10. Protect Yourself From Glare! Exposure to strong sunlight causes glare. This type of light reflects off objects causing them to appear brighter than they really are. To avoid this problem, wear protective eyewear whenever outdoors. Sunglasses should block 99% of all UVA/UVB rays.
11. Watch What You Look At! Looking directly into bright screens such as computer monitors, TVs, tablets, smartphones, etc., for long periods of time can cause eye strain (or digital eye strain). Instead look straight ahead while working at a desk or table.
12. Take Care With Contact Lenses! Wearing contact lenses increases the chances of developing an eye condition called keratoconus. Keratoconus affects one out of 1,000 people over age 40. It is characterized by thinning of the central layer of the front portion of the eyeball. As the cornea thins, it bulges outward forming irregular shapes. If left untreated, severe cases lead to loss of visual acuity.
13. Check For Refractive Errors! Most adults need glasses or contacts because their eyes no longer focus images clearly. However, some people develop refractive errors later in life due to aging. These include nearsightedness, farsightedness, astigmatism, presbyopia, and others. Some of these issues require surgery to correct. Others do not. Discuss any concerns with your optometrist.
14. See A Doctor Regularly! Visit your primary care physician regularly to check your eyes for signs of health problems. Have your vision checked annually starting at age 20.
15. Schedule Appointments Ahead Of Time! Make appointments with your ophthalmologist and optician early in order to get new prescription eyewear and lens fittings scheduled. Don’t forget about annual exams as well.
16. Follow the 20-20-20 rule! Your eyes work hard all day long and need a break now and then. If you work at a computer for long periods of time, the strain can be very high. To ease the strain, follow the 20-20-20 rule. It is recommended that you stop staring at your computer and look away for 20 seconds. The point is to take regular breaks from screen time.
Your eyes are one of the most important organs in your body. They help you see, process information, and interpret what you see. If they aren’t healthy, you may not be able to function normally.
Living a healthy lifestyle, maintaining a balanced diet, wearing protective and corrective eyewear, and protecting your eyes from the sun and foreign objects can’t protect against every eye condition. But they can all lower your odds of developing a problem that could hurt your vision. Protecting your eyes means decreasing the risk of eye disease and maintain your natural eyesight!
