Eye care is a great and tough task; however, if everybody could do the following six steps, it will become easy.
1. Do rest in time.
When you have looked things for about one hour, you need to take off your prescription glasses to have a five-minute break. If the conditions are limited, a break should be taken after at most two hours. The ways of taking a break include looking into the distance, closing the eyes, and walking around at will. The eyes should get suitable rest. Eye tiredness which lasts too long will lead to the damage of the eyes.
2. Do have fitting light.
When you are reading and writing, when you are at work or at home, you should not turn on too strong light that will stimulate the visual cells excessively and result in eye tiredness. Nevertheless, the environment should not be too dim, or you will feel hard to tell things apart and get tired easily. The strength of light should be moderate to see objects with difficulty. In addition to that, the light ought to be neither mixed nor disorderly. The temperature of light has to be close to the natural light (4000K to 8000K).
3. Do pay attention to the posture of using the eyes.
Generally speaking, a comfortable sitting posture should be taken to continue the eye activities. Do not be on all fours or on one side to read books. However, no matter what you are doing – reading a book, watching TV, and playing computer, the above-mentioned posture is unable to stabilize the visual position, which is easy to cause tiredness of eyes, neck, and shoulder.
4. Do take notice of the height of the chair and desk.
You’d better choose the right height of the desk and chair according your own height. The youth should pay attention to that in particular. If the height is not enough, the visual distance will become too short and the sitting posture will be incorrect, so as to lead to eye tiredness and other eye diseases, such as myopia.
5. Do care about nutrition.
In our daily life, you should pay attention to having a balanced diet, especially to supplying the vitamin A, B, and C.
When vitamin A is in short, the eyes’ ability of adjusting to the darkness will be decreased. In the most serious situation, it will cause nyctalopia. Vitamin A also prevents and cures the dry eyes. The best source of vitamin A is the animals’ liver, cod liver oil, milk and eggs.
In the retina, there is a lot of dissociative vitamin B2. Lack of Vitamin B will make eyes fear of light. The food rich in vitamin B is like grains, beans, and meats.
Vitamin C is one of components made up of crystal. If vitamin C is out of demand, cataract will easily developed.
6. Do turn on a light when watch the screen.
A light could moderate the stimulus from the screen, which could make eyes more comfortable. The light should be neither too bright nor too dim.

If you have rosacea and suffer from eye problems such as irritation, inflammation, decreased vision, or conjunctivitis, you could be suffering from ocular rosacea and should seek treatment from your doctor.
In order for an ophthalmologist to make a diagnosis, they will need to examine your symptoms, and your treatment will depend on the symptoms and the severity of the disease.
Why do you need an ophthalmologist as opposed to an optometrist to diagnose your ocular rosacea symptoms?
Ophthalmologists are different from optometrists in their training and in what they can diagnose and treat.
An Ophthalmologist is a medical doctor, and licensed to practice medicine and surgery, and treats all eye diseases, performs eye surgery and prescribes and fits eyeglasses and contact lenses.
Ophthalmologists are required to complete:
Four years of college and four years of medical school
One year of internship
At least three years of residency (hospital-based training) in the diagnosis and
medical and surgical treatment of eye disorders
An optometrist is licensed to practice optometry and determine the need for eyeglasses and contact lenses, prescribe optical correction and screen for abnormalities of the eye. In some states they can prescribe a limited number of drugs to help diagnose and treat certain eye conditions, but they do not generally perform surgery.
Optometrists attend two to four years of college and four years of optometric college.
Ocular Rosacea eye problems – ocular rosace symptoms
- Red, dry, itching, or burning eyes
- Sensitivity to light
- The feeling of grittiness in the eyes
- Blurred vision or other vision problems
- Eyelids that become inflamed and swollen
Some people with ocular rosacea have reported that certain triggers can cause their condition to be worse. The triggers include:
- Heat (including hot baths)
- Heavy exercise
- Sunlight
- Wind exposure
- Very cold temperatures
- Hot or spicy foods and drinks
- Drinking alcohol
- Menopause
- Emotional stress
- Humidity
Ocular Rosacea Treatment
Ocular rosacea symptoms are usually treated with oral antibiotics, such as tetracycline or doxycycline. Your doctor may also prescribe eye drops to increase tear production. They may also recommend that you use a humidifier or prescribe silicone plugs to close the tear drainage ducts – especially if you live in a dry climate.
Although there is no cure for ocular rosacea, the good news is that it can be treated in order to alleviate and lessen the symptoms.
Other ocular rosacea treatments may include:
Keep eyelids and eye lashes clean
ocular rosacea treatment
Wash the eyelids daily with diluted baby shampoo on a warm wet washcloth to
help keep the tear glands clear and unblocked. Place a hot compress on your eyes
for five minutes before the diluted baby shampoo is used to gently clean the
corners of the eyes.
Use hot compress
Apply a warm moist washcloth to the eyes several times a day. This will
be helpful for the infection.
Remove eye make up
Remove all eye make up before going to bed, and scrub the lashes very gently
using diluted baby shampoo.
Replace eye makeup
Doctors recommend replacing eye makeup every three to four months as there is a good chance of bacterial growth from the applicator after using it on your eyelids.
By replacing your eye makeup you can easily solve the problem of flaring or worsening of ocular rosacea symptoms.
New concepts for ocular rosacea treatment
Some doctors believe natural treatments are your best options because they work better, and they don’t have the serious side effects of conventional rosacea medicines. For many people, using the right natural treatments will provide long term relief from ocular and rosacea.

Eyes are one of the most important parts of our body. We all want to have bright and healthy eyes. However, you know what! Something in our everyday life is hurting our eyes. What is it? Let’s just have a look.
Alcohol
Alcohol hurts our eyes most. You may have found that our eyes will turn red and our body temperature goes high when we drink too much. That is because Alcohol can promote blood circulation and make capillary inflation. If we drink a lot, the blood vessels around our eyes which are very small will be easily broken and it hurts our eyes very much.
Tobacco
When we smoke, burning tobacco smoke inside the tar reduces vitamin B12 which is the necessary nutrient maintaining the normal function of the optic nerve. According to a survey conducted by WHO, 20% of the patients who get cataract are due to long-term smoking. Besides, scientific research has made it clear that tobacco can also cause wrinkles around the eyes. In addition, the second-hand smoke also does harm to our health and appearance. So let’s be away from tobacco.
Excessive Isolation
Too much ultraviolet radiation causes eye wrinkles, Cataracts and other eye diseases. Therefore, when we are out on a burning day, we should and must wear a pair of sunglasses to protect our eyes.
Improper Dieting
Improper dieting also hurts eyes. A research indicates that fresh vegetables and fruits rich in vitamin E, vitamin C, beta-carotene and zinc can prevent certain eye diseases and wrinkles, etc. When we are on a diet, we must increase the intake of fruits and vegetables.
Lack of Sleep
Some of us always have a lot of work to do. Sometimes, we even have to keep working till midnight and continue to work at eight the next morning. That’s to say our eyes can only rest for less than 7 eyes. As a result it is easy for our eyes to get tired. What’s worse, they will also suffer from the pouch and wrinkles. Therefore, take every chance to have just a short rest.
Eyes are compared to the window of our heart. If your eyes get hurt, how can you enjoy the beauty of the world? So what I want to say is please keep away from all above aspects and keep your eyes healthy.

Vision changes
With aging, the quality of vision worsens due to reasons independent of aging eye diseases. The area of the pupil governs the amount of light that can reach the retina. The extent to which the pupil dilates also decreases with age. Because of the smaller pupil size, older eyes receive much less light at the retina. In comparison to younger people, it is as though older persons were wearing medium-density sunglasses in bright light and extremely dark glasses in dim light.
To maximize the light entering the eye, make sure that your eye glasses have anti-reflective coating. Anti-reflective lens coatings significantly reduce surface reflectance and allow greater light transmission through the lens. When AR coating is applied to both the front and back surfaces of a lens, the percentage of transmitted light increases to approximately 99% (compared to 90-92% with non-ARC lenses).
Aging causes a dramatic slowing in dark adaptation. Color vision changes cause some reduction of ability to discriminate blues and blue-greens. The yellowing of the lens is believed to be responsible for this effect. The aging lens and cornea causes glare by light scattering, especially for shorter wavelengths. Aberrations of cornea also increase with age, leading to poor vision especially when the pupil dilates as in the dark.
The most aggravating aspect of vision in an older person seems to be the feeling that it does not work as effortlessly or as quickly as it did in younger days. They must concentrate harder and require higher levels of illumination than they formerly did in order to have the same perceptual results.
Lighting the way
Everyone’s vision deteriorates with age, but there are ways to lessen its impact. Good lighting can make the difference between seeing and not seeing for older adults, especially in your homes, stairways, kitchen, living rooms etc. Naked bulbs: These are worst for older eyes, producing a glare that can be disorienting and painful. Task lighting: Light should be focused on the work, not toward the eyes. A good choice is a CFL with electronic ballast that starts up without flickering. Bathroom lighting: Lots of light should be provided overhead and even in the shower, where accidents are particularly common.
Anatomic changes
Aging causes laxity and downward shift of eyelid tissues and atrophy of the orbital fat. These changes contribute to the etiology of several eyelid disorders such as ectropion, entropion, dermatochalasis, and ptosis. The higher eyelid skin crease and ptosis may be due to age related disinsertion of the levator muscle aponeurosis, and to involutional atrophy of the orbital fat. The horizontal eyelid fissure shortens by about 10% with aging. With aging a prominent white ring develops in the periphery of the cornea- called arcus senilis. The corneal endothelial cells gradually decrease in number. The vitreous gel undergoes liquefaction and its opacities – visible as floaters gradually increase in number.
Aging Eye Diseases
Cataract: Cataract (‘safed motia’) is a clouding or opacity of the normally transparent lens inside the eye. It prevents the light rays passing onto the retina. The picture that the retina receives becomes dull and fuzzy. The normal process of aging causes the lens to harden and become cloudy (opaque). This is called age-related cataract and it is the most common type. It can occur anytime after the age of 45 years.
Glaucoma: Glaucoma (kala-motia, kala-paani) is a serious condition that involves an elevation in pressure inside the eye caused by a build-up of excess fluid. Left untreated, this pressure can impair vision by causing irreversible damage to the optic nerve and, eventually, blindness.
Macular Degeneration (ARMD): The macula is the part of the retina, which provides us with central vision and allows us to see fine detail, such as recognizing a face, reading, or watching television. Macular Degeneration is a condition in which the macula gets damaged. It is often related to aging, and is commonly referred to as Age-related Macular Degeneration (AMD).
Presbyopia: If you have presbyopia, you have the loss of the ability to focus up close that occurs as you age. Most people are between 40 and 50 years when they realize for the first time that they can’t read objects close to them.
Macular Hole: A macular hole is a small break in the macula, located in the center of the eye’s light-sensitive tissue called the retina. A macular hole can cause blurred and distorted central vision. Macular holes are related to aging and usually occur in people over age 60. It is 4 times more common in females.
Diabetic Eye Disease: Retinopathy is usually due to damage to vessels in retina. Retinopathy is usually caused by Diabetes (DM), but is sometimes caused by other diseases such as high BP.
Dry Eye: The most common cause of dry eye is a failure of the glands in your eyelids to produce tears, which often occurs as part of the ageing process.
The real problem of blindness is not the loss of eyesight. The real problem is the misunderstanding and lack of information that exist. If a blind person has proper training and opportunity, blindness can be reduced to a physical nuisance.
