The importance of eye evaluations

It is possible that doing a visual examination does not seem to be the most exciting activity you can do. Contact lens wearers are required to perform this eye evaluation even if they have no problem. The importance of these assessments is often called into question, but even if it is not the first priority on your list, you should not delay these reviews, as they can save your vision.

When should you go to an appointment?

We all needed to do eye evaluations regularly. Adults, without risk factors or a family history of eye problems, should have a revision every two years and, after 60, once a year. Children should take an exam at 6 months, at 3 years of age, before starting primary school, and then annually. The view is strongly related to the learning process, hence the importance of these assessments in children.

Early detection of some problems can save your vision

Many ocular pathologies, such as glaucoma and diabetic retinopathy, do not show symptoms in their initial stages. Early detection and treatment can reduce the risk of visual impairment or permanent loss of vision.

Save more than just your vision

A recent study (article in English) reveals that eye health professionals are often the first to detect signs of chronic systemic pathologies. These professionals are able to visualize blood cells without obstacles that may indicate early signs of high cholesterol, diabetes and hypertension.

7 tips for maintaining eye health

Eye Health Day today (10). According to the International Blindness Prevention Agency, an organ associated with the World Health Organization (WHO), in Brazil a person over 80 years of age increases the risk of being blind by up to 30%. In addition, more than 100 thousand Brazilian children have some type of visual impairment.

The ophthalmologist, Dr. João Luiz explains that, some lifestyle habits can improve eye health, ensuring more quality and comfort for vision.

For this, the expert recommends seven tips:

1. Sleep at least eight hours a day

Sleep and sleeping hours influence body and eye fatigue. Sleeping less than eight hours can cause redness, tired eyes and swelling.

2. Avoid drinking alcoholic beverages

Although alcoholic beverages are metabolized by the liver, they produce toxic waste, which favors premature aging of the eye cells. In addition, alcohol causes dehydration, also affecting the eyes.

3. Have a balanced diet

Healthy eating habits influence the entire body, including the eyes. Intake of dark green vegetables is indicated, as they provide beneficial vitamins to the retina.

4. Don't forget your sunglasses

Glasses with ultraviolet (UV) protection should always be used, as UV light is harmful to the cells of the retina, causing their premature aging. In addition, the incidence of UV rays in the eyes can cause early cataracts and the development of degenerative diseases of the retina.

5. Do not neglect during dry weather
The low humidity of the air causes irritation, burning and redness of the eye, as it worsens the evaporation of the tear. Fans and air conditioning should be avoided as they dry out your eyes even more. In this case, the use of lubricating eye drops, known as "artificial tears", is essential.

6. If you need prescription glasses, be sure to wear them

Eyeglasses must be used correctly to avoid eye problems and discomfort, such as headaches and eye strain.

7. Perform eye consultations

The doctor will assess the quality of vision and eye conditions, and update the glasses if necessary. Tests to analyze intraocular pressure and the retina should be done periodically.

Types of Eye Drops


Eye drops are used to treat all types of eye problems such as eye discomfort, dryness, allergy or more serious problems such as conjunctivitis and inflammation, for example. Eye drops are liquid dosage forms, which must be applied to the eye, in drops, and the number of drops to be used must be indicated by the doctor.

The type of eye drops to be used depends on the problem to be treated and should only be used under the doctor's recommendation because although it is a topical liquid, it is a medication and even if it relieves the symptoms, it may not be treating the disease, and may just mask symptoms.

Lubricating eye drops are used to treat dry eye syndrome, burning and irritation caused by dust, smoke, pollutants, chemicals, ultraviolet rays, dry or excessive heat, air conditioning, wind, computer or cosmetics. They can also be used by people who wear contact lenses and feel a lot of dry eyes.

Some examples of eye drops indicated to lubricate the eyes are Can-C Eye Drops, Lacril, Trisorb, Dunason or Lacrifilm, which can be purchased at pharmacies without the need for a prescription. Antibiotic eye drops are used to treat eye infections caused by bacteria, called bacterial conjunctivitis.

The Use Of Eye Drops In The Treatment Of Glaucoma


Because it is a silent disease, glaucoma can lead to irreversible damage to the eyes. Once we have or feel any eye disease, we immediately think about using eye drops and the like, during treatment. With regard to glaucoma, the disease needs follow-up, as well as prolonged treatment to prevent possible blindness. However, due to a simple lack of information, many patients do not adhere to the treatment necessary to solve this condition. One of the most important causes considered in cases like this is the incorrect use of eye drops. Most patients do not properly administer the use of these eye drops. Most treatments for glaucoma aim to decrease and control intraocular pressure, which can damage the eye's optic nerve, which transmits visual information to the brain. Eye drops are often the first choice for the treatment of glaucoma and can be very effective in controlling this pressure. Consult your ophthalmologist to find out which eye drops you should use for glaucoma, as each case is a case.

Eye drops are classified by the chemical ingredient that helps the drug to work. Let's go to the types:

Prostaglandins: This glaucoma eye drops usually have the best compliance for the patient because they are needed only once a day. Prostaglandins generally work by relaxing the muscles in the structure inside the eye to allow better fluid outflow, thereby reducing the accumulation of eye pressure. There are possible side effects, which include burning and burning, changing the colour of the eyes and stretching and curling the lashes. Beta-blockers: used in a variety of glaucoma eye drops, beta-blockers were at the same time the drugs of choice in the treatment of glaucoma.


These eye drops have the role of reducing heart rate and can cause adverse side effects in individuals with certain heart problems, lung problems (such as emphysema), diabetes, depression or other conditions. For these reasons, be sure to discuss your medical history in detail with your ophthalmologist before using beta-blockers. Alpha-adrenergic agonists: these drugs work by decreasing the rate of aqueous fluid production and can be used alone or in combination with other anti-glaucoma eye drops. Many patients with glaucoma require more than one type of medication to control eye pressure. For that reason, some ophthalmic pharmaceutical companies have produced combined eye drops that may include two different glaucoma drugs in the same bottle. It is important that your ophthalmologist can prescribe combined medications to reduce this eye pressure. There is a wide variety of options available to treat glaucoma, and these include eye drops, laser procedures and surgery. All are designed to decrease eye pressure and thus protect the optic nerve. Today, eye drops are often the first choice for treatment and for most people, a combination of drugs and laser treatment can safely control eye pressure for years. Medicines for the treatment of glaucoma are classified by their active principle, as mentioned in this article earlier.




Naturally, the treatment of this condition seems simple, because it only uses eye drops, but it is not that simple, as patients undergoing glaucoma treatment may not take their medications. One reason is that they simply forget, so discipline is everything! Remembering to take a daily medication is one of the challenges in treating any chronic condition, and glaucoma is no exception. Some ways to help remember include linking regular daily activity (such as brushing your teeth) to taking medication or setting timed reminders, such as an alarm clock or cell phone. A second factor in not taking medication as prescribed is an investment. These glaucoma eye drops can be quite expensive. Your ophthalmologist will work with you to recommend the best choice for you. Another factor that influences the use of eye drops is side effects. In addition to the specific adverse reactions of the active ingredient, irritation of the ocular surface (conjunctival and corneal) can occur with any type of eye drops. This irritation can be new in a patient who has never had symptoms before or it can manifest as worsening of the disease of the pre-existing ocular surface, such as a dry eye for example.
