Eyeglasses and contact lenses are both used for vision correction. Both of the options have their advantages and disadvantages but a number of factors like lifestyle, comfort and age etc. are important while deciding which one to choose. Here is a list of the fundamental differences between using spectacles and using contact lenses:

1. Distance from the cornea
Lenses are worn directly on the eye and are in constant physical contact with the cornea while glasses are worn over the eyes. Contact lenses may cause infections in the eye because the user has to touch the eye in order to wear them and to take them off.

2. Difference in vision
Since the lenses of spectacles are a little distance away from the eye, vision can be slightly distorted but contact lenses can provide natural and accurate vision. Also, side vision is not improved by glasses as you have to turn your head to see what is beside you. The contacts move around with your eyeballs and the peripheral vision is in focus.

3. Ease of use
Some people find eyeglasses difficult to use because of the constant weight on the face and the obstruction caused by the frames of the glasses. There may also be a constant need to adjust the frames. Often eyeglasses slip down the nose when you sweat or engage in rigorous physical activity. Contact lenses are free from all these hassles - they are not distracting or obstructive and so they are extensively used by dancers and athletes. Spectacles is very uncomfortable to wear during the rains or in humid weather because they fog up.

4. Infections and complications
Contact lenses can get displaced inside the eye and they can be difficult to reposition. They also cause the eyes to itch and water if you wear them for a very long time at a stretch or if tiny dust particles enter your eyes. The use of eyeglasses is far more flexible in this respect - they can be removed in case your eye itches or burns, but regular use of glasses causes dark circles and bags under the eyes.

5. Aesthetic differences
People often prefer contact lenses as they do not change the physical appearance - they help you look natural and you can also use colored lenses to change the color of your eyes. Glasses may look slightly unnatural but some people also prefer them for the fashion quotient.

Lens Vs Specs

Hypertension is a killer disease whose symptoms develop late when the damage is in advanced stages. Hypertensive Retinopathy is one such disease.

It damages the retina of eyes. Since retina is responsible for vision formation, Hypertensive Retinopathy can result in loss of vision. It is of grave concern that in most cases, Hypertensive Retinopathy is diagnosed later.

This is due to the fact that there are often no symptoms in the early stages of the disease. In some cases, where symptoms do manifest, patients may experience pain in the eyes, reduced vision, or headache.

What Happens in Hypertensive Retinopathy

People suffering from long term hypertension are susceptible to Hypertensive Retinopathy. Long-term hypertension affects the small and narrow blood vessels that join arteries to capillary blood vessels taking blood to different parts of the eye. These blood vessels become narrow with time if hypertension in the eyes continues unabated. This narrowing is more common in young adults compared to older people. Such unabated systemic hypertension also leads to leakage of fluid. This is why in some cases of Hypertensive Retinopathy, patients may experience exudation. Ultimately, Hypertensive Retinopathy may lead to damage to retinal blood vessels.

Risk Factors

Long standing hypertension is the number one risk factor for Hypertensive Retinopathy. People who are suffering from longer hypertension become most susceptible for this ailment.

However, studies have shown that hypertension for more than 5 years can even make people susceptible to this ailment.

Diagnosis

Diagnosis is done by Funduscopic Examination. The doctor would look at the eyes of the patient through an Ophthalmoscope which has different lenses. The Ophthalmoscope illuminates the retina and the doctor looks at the retina with different lenses. He can get a view of the retina, including blood vessels and optic nerve disks.

Findings of Diagnosis

For a person suffering from Hypertensive Retinopathy, this examination is likely to show:

Constriction of the arterioles.

Changes in the walls of retinal blood vessels.

Flame-shaped hemorrhages in the retina.

Yellow and hard exudates.

Spots in the shape of cotton wool.

Swelling of the optic disc.

Treatment

The primary treatment for Hypertensive Retinopathy is controlling blood pressure of the eyes. Some lifestyle changes like reducing the intake of salt, avoiding tobacco, etc., may bring down or control systemic hypertension in the eyes. In many cases, doctors may just recommend lifestyle modifications. Nevertheless, it completely depends on the extent of the damage and whether or not there is any fluid accumulation.

If the doctor feels that lifestyle modification is not enough, he may go for medicines that help the patients to control blood pressure effectively.

If the problem is in advanced stages and there is fluid accumulation behind the retina, the doctor may go for Intravitreal injection or Laser Therapy to control the edema.

Conclusion

Eyes are one of the most significant part of the body, this is why it is important for people to take care of it. In case of disease like Hypertensive Retinopathy, one must consult a doctor before opting any treatment or medicines.

Hypertensive Retinopathy - Everything About It!

Eye allergies are characterized by red and itchy eyes which may result from various allergens coming in contact with the eye. Eye allergies can cause swelling of the eyelids, redness in the eyes and may also lead to conjunctivitis. Conventional treatments prescribe eye drops containing chemicals that may aggravate the condition.

Homeopathy-the best natural treatment for eye allergies-

The allopathic system relies mainly on steroids and anti-allergic medicines for the treatment of allergic conjunctivitis. Even  then, it is unable to cure the allergy. It only ends up controlling it or keeping the symptoms under check. In homeopathy, the intention is to completely cure the allergy. Homeopathy recognises that the immune system of the body sometimes overreacts to some seemingly harmless things. This overreaction of the body is the root cause of problem. 

Therefore, it tries to correct the immune system. In this the medicines that are used by homeopathy are perfectly natural medicines. None of the medicines are chemical in nature. They are made from natural sources like plants or fruits or vegetables or minerals. The basic material is further diluted by a special mechanism which reduces the content of the original matter while increasing its latent healing powers. That is why these natural homeopathic medicines do not have any side effects.

The homeopathic remedies for eye allergies are:

1. Euphrasia

This remedy is used to treat allergies which cause watery discharge from the eyes and which tends to have burning sensation on the skin. The condition tends to aggravate during the evening and in closed spaces.

2. Argentum nitricum

Argentum nitricum is used to treat eye allergies which show symptoms such as aversion to bright light and conjunctiva swelling. The symptoms may be accompanied by gas in the abdomen.

3. Ruta

This is an effective remedy for allergic conjunctivitis where you may experience a constant feeling of something being stuck in the eye. There may also be swelling in the eyelids, redness and continuous watery discharge.

4. Pulsatilla

Pulsatilla is recommended if symptoms such as itchy eyes, yellowish discharge from the eyes and swelling of the eyelids are present. Hot and humid climatic conditions tend to aggravate this.

5. Apis Mel

Apis Mel is another homeopathic remedy that is used to treat eye allergies. Symptoms such as swelling of the eyes, burning sensation and intense pain in the eyes are very common. The symptoms are aggravated by hot weather conditions and direct exposure to the sun.

3) Get eyes examined - Have regular eye exams to check for diabetes and high blood pressure, if these health problems already exist in the family.
4) Do not smoke - People who smoke are more risk of having age-related eye problems.
5) Exercise your eyeballs - Roll the eyeballs up and down, and lift and right without moving your position. Repeat this exercise about 5 to 10 times. This helps relax the muscles in your eyes.
6) Distance eyes from screens - If you work on the computer, make sure there is enough distance between the screen and your eyes. Sit at least 22-28 inches away from the screen.

7 Ways To Care For Your Eyes Without Making Any Effort

Eye Strain is an umbrella term that denotes a number of symptoms that relate to the extended use of eyes as well as discomfort that may come from excessive smartphone and computer use. This condition may or may not lead to significant eye damage and is usually characterised by blurry vision, headaches and a feeling of dryness in the eye as you blink less which creates less tears. This may happen due to the extended use of the eye when you are following objects on a screen or staring at a screen for too long. So, is eye strain the cause of your headaches? 

Find out more in this article.

Causes: Eye Strain or Asthenopia is caused by concentrating on visually intense tasks like reading from texts that have a fine print, the use of computers and other screens for prolonged periods, and trying to focus on objects in the dark. This can lead to distress of the muscles in this area which can also cause eye strain leading to a variety of symptoms including double imagery and even headaches and mild migraine like conditions.

Eye Muscle Imbalance: When there is eye strain which leads to headaches, it can also give rise to eye muscle imbalance which makes it difficult to concentrate with both eyes at the same time. In such cases, one may need bifocal glasses so as to fix the issue and prevent such debilitating headaches to remain on a persistent basis.

Diagnosis: Digital eye fatigue and ocular eye strain leading to headaches can be diagnosed by a doctor with the help of regular eye examinations. In any case, one should have the eyes checked at least once a year. This is especially important if your job involves sitting in front of the computer screen for prolonged hours.

Symptoms: There are a variety of symptoms of these headaches that are caused by eye strain. Apart from blurry vision which does not allow the patient to see properly and clearly without glasses, it can also cause headaches with symptoms like nausea and sensitivity to light. Retinal or eye migraines do not necessarily have to come with headaches, but the pressure can be painful enough.

Treatment: To begin with, the best form of treatment for headaches born from eye strain includes prevention which can be done by getting plenty of rest and sleep even as we limit the hours spent in front of the screen. One can also lower the resolution of the screen and make it more ambient. Also, the screen should be placed at a considerable distance from the eyes. The doctor can also prescribe glasses and eye drops for better eye lubrication.
