Ocular diseases remain a significant health burden, with more than 280 million reported cases of ocular diseases worldwide, as per the world health organization (WHO). Ocular diseases are spread among a wide age group, though it is more prevalent in the elderly. Despite the increased prevalence of eye diseases, most patients remain undiagnosed as they are asymptomatic until the advanced stage of the condition. Travelers are no exception in getting eye diseases during trips.

What Are the Various Risk Factors Associated With Eye Diseases Among Travelers?

Several factors contribute to increasing the risk of contracting eye diseases by travelers. The risk factors causing eye lesions are:

  • Exposure to dry air in planes, desert climates, or air-conditioned rooms.

  • Direct sunlight exposure.

  • Exposure to salty or chlorinated water in the swimming pool, beaches, baths, etc.

  • Exposure to various etiological agents like viruses, dust, bacteria, allergens, etc.

  • Subjection to extreme weather conditions.

Which Eye Diseases Are More Prevalent in Travelers?

The most common eye disease in travelers is conjunctivitis (inflammation of the inner lining of the eyelid). Conjunctivitis may be cosmopolitan (allergic, bacterial, or viral) or tropical (arboviral infections).

The other ocular conditions which travelers frequently encounter are:

  • Dry eyes syndrome.

  • Excessive production of tears.

  • Inflamed eyes.

  • Trauma to the eye.

  • Keratitis.

What Are the Clinical Presentations of the Various Eye Diseases Encountered by Travelers?

Patients suffering from various eye lesions present with different clinical presentations.

  • Dry eyes are the most common eye condition encountered by travelers due to exposure to air-conditioning, exposure to harsh weather conditions, and chronic use of topical anti-inflammatory drugs. It manifests as drying of the eyes with the presence of constant irritation sensation in the eyes.

  • Watery eyes are accompanied by pain, redness, and swelling.

  • Inflammatory conditions affecting the eyes may be endogenous or acquired by several causative factors, including viruses, bacteria, and fungi. The most common inflammatory conditions of the eyes are conjunctivitis and keratitis.

  • A foreign body sensation in the eyes along with redness and swelling.

  • The presence of trauma to the eyes.

  • Damage to the retina in diabetic patients.

  • Retinal bleeding is common in mountain climbers.

What Are the Diseases of the Eye That Are Specific to Hot Climatic Conditions?

A hot and humid climate leads to the development of several eye lesions. The common eye lesions of the tropical and subtropical regions are:

  • Onchocerciasis. It is caused by the Onchocerca volvulus parasite and manifests as inflammation of the conjunctiva, anterior chamber, and keratitis.

  • Loiasis. Loa loa parasite causes loiasis, in which conjunctivitis and a foreign body are present.

  • Gnathostomiasis. It also shows the presence of conjunctivitis.

  • Trypanosomosis. It is mostly seen in Africa and manifests clinically as swelling of the eyelids.

How to Take Care of the Eyes in a Tropical Climate?

Any ocular condition with severe manifestations requires consultation with the ophthalmologist or primary care physician at the earliest. People with pre-existing ocular problems should take precautions while traveling. The following steps should be followed while traveling to a tropical region:

  • Carry an extra pair of glasses, sunglasses, and lenses while traveling.

  • Mild cases do not require immediate medical help. However, severe cases need to be immediately shown to an expert.

  • Infectious conditions mostly require a topical antibiotic application in the form of eye drops, ointments, or suspension.

  • Antiinflammatory drugs are administered intralesionally at the region of inflammation by the specialist.

Does Only Hot and Tropical Weather Cause Eye Problems?

Even though tropical and subtropical climates are most commonly linked to eye problems, colder climates also cause eye lesions.

What Are the Eye Problems Seen in Patients Traveling to Colder Climates?

People traveling to colder climatic conditions need to take care of their eyes against the following eye problems:

  • Dryness of the eyes.

  • Excessive tearing is seen due to exposure to the chilly winds or seasonal allergies.

  • The eyes become more sensitive to light. Patients also complain of more blinking and discomfort. This is attributed to more light reaching the eyes after reflecting from the snow surface.

  • Redness of the eyes.

  • Tenderness.

  • Inflammation of the eyes.

  • Swollen eyelids.

  • Changes in vision are seen due to a decrease in moisture content in the eyes, along with an increase in the amount of light entering the eyes.

How to Manage Eyes in Colder Climate?

The following measures can manage the eye conditions occurring in winter:

The dryness of the eyes can be minimized by using artificial tears and keeping the surrounding humidified and warm.

  • Runny eyes, if it is caused by an allergen, can be managed with over-the-counter topical anti-allergens.

  • Sensitivity of the eyes can be prevented by using ultraviolet radiation protective goggles or sunglasses.

  • Redness and inflammation of the eyes are managed best by using topical anti-inflammatory agents, cold compress, and pain medications.

  • Disturbances in vision in the cold regions are controlled by using artificial tears, moving to warm conditions, and keeping the eyes' moisture intact.

What Should Be Done by Glass Wearers While Traveling?

People who wear glasses should be extra cautious while traveling. A few precautionary steps that help people with glasses are:

  • Always pack an extra glass of eyewear while traveling.

  • Always carry a copy of the prescription from the specialist.

  • Visit an ophthalmologist before travel.

  • Always consult a specialist in case of emergency while traveling.

When to Visit an Ophthalmologist Immediately?

  • Severe pain in the eye.

  • Redness and pain in the eyes.

  • Distortion in vision.

  • Ulceration in the eyes.

  • Uncontrolled tearing of the eyes.

  • Retinal detachment and bleeding.

How to Take Care of the Eyes While Flying?

Flying can change air pressure and can cause dryness of the eyes, formation of bubbles inside the eyes, increase intraocular pressure, and cause serious damage to the eyes, thus leading to defective vision.

People can follow a few simple measures to avoid dryness of the eyes while flying -

  • Avoid wearing contact lenses for long hours.

  • Keep an extra pair of glasses when traveling.

  • Turn off the air-conditioner.

  • Use lubricating agents.

How to Care for the Contact Lenses While Traveling?

A few general guidelines that can be followed by contact wearers while traveling include:

  • Avoid wearing contact lenses while traveling long distances.

  • Removal of lenses is beneficial while flying.

  • Regular moisturizing of the eyes.

  • Lens wearers going to a sunny destination should use adequate ultraviolet protection or sunglasses.

  • Removal of lenses while swimming helps prevent infection.

  • Always keep an extra lens solution and avoid cleaning the lens with water.

  • The lens should be properly stored. The use of disposable lenses is preferred while traveling to tropical and subtropical regions to avoid infection.

  • Always carry an extra pair of lenses in a clean, transparent plastic bag with a seal while flying in a plane.

Conclusion

Ocular diseases are the most frequently occurring condition in travelers. Although mild eye lesions can be managed with over-the-counter medications, serious conditions require immediate consultation with a specialist. It is crucial for people to follow a few eye care tips while traveling to avoid any complications.

Frequently Asked Questions

Utilizing a screen filter and adjusting the lighting to lessen glare can also be advantageous. Additionally, keeping the eyes at a comfortable distance from the screen and sitting up straight will prevent eye strain and discomfort during the trip.

3.

What Are the Five Ways for Eye Protection?

There are several crucial strategies to safeguard the eyes and keep them in good condition. Initially, wearing sunglasses that offer 100 percent UV protection will safeguard the eyes from damaging rays. The 20-20-20 rule, which recommends taking a 20-second break every 20 minutes to look at something 20 feet away to relieve eye strain, is also essential. A balanced diet of minerals like omega-3 fatty acids, vitamin C, and zinc is also important for maintaining excellent eye health. Smoking should be avoided, and screen time should be minimal.

4.

How Can Individuals Protect Their Eyes While Using a Phone?

A few easy precautions may be implemented to protect the eyes while using the phone. Start by ensuring optimum lighting through glare reduction and screen brightness adjustment. Practice the 20-20-20 rule: every 20 minutes, look away from the screen and concentrate for 20 seconds on an object 20 feet away. Reduce the amount of blue light your screen emits by adjusting the settings, and think about using blue light-blocking eyewear. Last but not least, keep a comfortable distance-ideally between 16 and 18 inches- between the eyes and the screen.

5.

Why Will the Individual’s Eyes Hurt While Traveling?

Individuals may feel pain and discomfort when they travel for various reasons. To begin with, spending a lot of time reading or staring at displays while traveling can tire and hurt the eyes. Second, air pressure and dry cabin air alterations may irritate and dry up the eyes. Additionally, traveling might make the eyes more sensitive to light and cause pain from exposure to extreme light. While traveling, these symptoms can be relieved, and the eyes can be protected by taking breaks, eye drops, and wearing shades.

6.

How Many Hours of Screen Time Is Suggested for Maintaining Healthy Eyes?

Limiting daily screen time, which includes time spent on the computer, TV, and smartphone, is recommended to up to two to three hours. It can lessen eye strain and improve eye health by taking regular breaks, using appropriate lighting, and keeping a reasonable distance from the computer. A professional in eye care should be consulted for more specific advice.

7.

Which Vitamin Is Good and What Are the Foods Good for Eyesight?

For sustaining healthy eye health, vitamin A is necessary. It is essential for maintaining normal vision and avoiding issues like night blindness. This vitamin promotes the retina's functionality and aids in the eyes' ability to adjust to variations in light. It also aids in creating pigments that shield the eyes from damaging ultraviolet (UV) radiation. Including vitamin A-rich foods in the diet, such as carrots, spinach, sweet potatoes, and eggs, can give them the nutrients they need to keep their eyes healthy and operating at their best. A diet high in berries, carrots, and other colorful fruits and vegetables, as well as leafy greens like spinach and kale, can support healthy eyes. The vital minerals in these foods, such as vitamin C, E, beta-carotene, and lutein, help to support eye health and protect against age-related macular degeneration and cataracts.

8.

Is Night Mode Better for Individuals’ Eyes?

Unlike conventional light mode, night mode, sometimes called dark mode, is frequently considered healthier for the eyes. Using dark colors lessens the amount of blue light that screens emit, which can cause eye strain and interfere with sleep cycles. Night mode can be very helpful in low-light conditions as it lessens glare and increases contrast. To preserve general eye health, utilizing the proper screen brightness and taking frequent pauses is crucial. However, individual preferences may differ.

9.

How to Strengthen the Individual’s Eyes?

There are numerous exercises one can do regularly to strengthen the eyes. First, ensure adequate illumination and keep reading items and displays at a comfortable distance from the face. Take regular rests to relax the eyes and sharpen the ability to see far-off objects. Exercises for the eyes, such as rolling eyes, blinking, or massaging the eyes, can be helpful. Maintain a healthy lifestyle by eating a balanced diet, exercising regularly, and getting enough sleep. To address any potential difficulties, think about scheduling routine eye exams.

10.

How Can the Individuals Clear a Blurry Vision?

Ensure the individuals get enough sleep and give the eyes a break from screens and demanding visual work first. To moisten the eyes and lessen strain, blink frequently. To lessen glare, adjust the illumination in the vicinity. If they wear glasses or contacts, ensure they are fitted correctly and clean. It is crucial to speak with an eye care specialist for a thorough examination and the best course of action if the blurriness worsens.

11.

How to Clear the Individual's Eyes?

There are a few easy measures one can take to relax the eyes. Keep any additional dirt or bacteria from getting into the eyes, and wash the hands properly first. Then, rinse the closed eyes with a sterile eyewash solution or a stream of clean, lukewarm water. Blink the eyes a few times gently to help remove any irritation. Avoid rubbing the eyes if there is chronic irritation or vision issues, and seek further advice from a medical professional. Keep in mind that sustaining good eye health requires adequate eye care.

12.

Can Airplane Pressure Damage the Individual’s Eyes?

Although discomfort and brief fluctuations in eye pressure are possible under airplane pressure, significant eye damage is uncommon. When the cabin pressure changes during takeoff and landing, the inner and outer pressures of the eye may momentarily become out of balance. 
This might cause minor eye irritation or impaired vision. To maintain passenger safety, the cabin pressure is carefully controlled, reducing the possibility of serious eye damage. It is advised to drink plenty of water, use lubricating eye drops if necessary, and speak with a doctor if they have any persistent eye problems.
