Contact Lenses

6 Risks of Long-Term Contact Lenses Use

Contact lenses are medical devices worn directly on the corneas of the eyes for vision correction or aesthetics purposes. Although useful, they can put the eyes at risk of infections and inflammation, especially when used for an extended period of time. This is because the lenses cover the entire corneas, reducing the amount of oxygen that reaches the eyes from the environment.

Several risks of prolonged wearing of contact lenses include:

Dry Eye Syndrome

1. Dry Eye Syndrome

Dry eye syndrome (keratoconjunctivitis sicca) is caused by insufficient or poor quality tears. Its symptoms include burning or stinging sensation, sandy or gritty feeling, sore eyes, light sensitivity, blurry vision; and eye itchiness, tiredness, dryness, and redness. Inadequate supply of oxygen reduces the tears produced by the eyes so if you have borderline dry eye syndrome, you may feel especially uncomfortable with your contacts on. If you wear contacts for too long, the protein deposits also build-up, which can make your eyes feel even drier.

 

 

Pink Eye

2. Pink Eye

Bacterial infection from contact lenses can lead to pink eye (conjunctivitis), an inflammation or swelling of the conjunctiva. Symptoms of conjunctivitis include pink discoloration to the whites of eyes, swollen eyelids, itching or burning sensation, discharge or excessive tearing, and increased sensitivity to light.

 

 

 

Corneal Ulcer 3. Corneal Ulcer

Corneal ulcer (microbial keratitis) results from the rubbing of contact lenses against the eyes’ surface, creating open sores in the outer layer of the corneas that may enable bacteria to penetrate the eyes. Corneal ulcer causes pain and redness, mild to severe eye discharge, and blurry vision.

 

 

 

4. Corneal ScarringCorneal Scar

Corneal scars develop when contact lens cause abrasions or injury to the Bowman’s membrane (smooth and nonregenerating layer between the superficial epithelium and the stroma) and the stromal layers. Scar can also form when the corneal ulcer penetrates the Bowman’s and the stromal layer. Corneal scarring can lead to impaired vision.

 

 

 

 

 

Vision Loss

5. Vision Loss

Corneal ulcer scarring can lead to permanent vision loss, especially if the ulcer is centrally located in the cornea and is deep and invasive. Vision loss after corneal ulcer occurred more frequently with extended-wear soft contact lenses compared with extended-wear silicone hydrogel contact lenses.

 

 

 

Abnormal blood vessel growth

6. Abnormal blood vessel growth

Wearing contact lenses for too many hours or too many years can cause abnormal blood vessel growth in the cornea (corneal neovascularization). Blood vessels normally circle the cornea at the limbus or the border of the cornea and the sclera (white part of the eye). Any growth beyond this point hampers your vision.

 

 

 

Risks of prolonged contact lenses use differ for each person. If you decide to use them, always keep them clean and stored properly, follow your lens-wearing schedules, and set appointments with your eye doctor for follow-up care. Also, make sure to have an up-to-date pair of eyeglasses to give your eyes a break.

For permanent and long-term solution to vision problems, consider getting LASIK (laser-assisted in situ keratomileusis), which is the most advanced type of vision correction that uses laser energy to reshape the cornea and correct refractive errors, such as nearsightedness, farsightedness, and astigmatism.

10 Bad Habits that Cause Vision Problems

Poor eyesight can be caused by many factors including genetics, age, and environment. In today’s digital world, however, most vision problems are often the result of poor eye care and bad habits.

If you want to maintain your healthy vision for years to come, it’s time to break these unhealthy habits:

Screen Time

1. Too much screen time

Spending too much time in front of your laptop or smartphone greatly reduces the number of times you blink, which is essential for eye cleaning and lubrication. Blinking also stimulates the retina and gives your brain a rest. Prolonged exposure to screen-based devices also causes digital eye strain with symptoms including headache, burning eyes, blurred vision, and disrupted sleep. Severe eye strain can lead to permanent vision problems.

 

 

 

 

 

 

Working at Night

2. Not getting enough sleep

Lack of sleep can lead to eye strain and eye fatigue. Sufficient sleep of 6-8 hours daily helps your eyes recover from a long day of use and provides continuous eye lubrication, which clears out accumulated irritants.

 

 

 

 

 

 

 

Wearing Contact Lense

3. Prolonged wearing of contact lenses

The eyes’ oxygen supply is limited when wearing contact lenses. The longer you have them on, the riskier the game. Without oxygen, the cornea swells up and expose a small gap where bacteria can enter, increasing your risk for keratitis and other eye infections. Long-term use of contact lenses can also lead to alterations in the cornea and corneal scarring, which affect vision.

 

 

 

 

 

 

A Man Rubbing his Eyes

4. Rubbing your eyes often

The seemingly harmless habit of rubbing your eyes can have serious consequences. Aside from the risk of allergic conjunctivitis and eye infections, it can also lead to keratoconus, the thinning and reshaping of the cornea from round to cone, which causes a progressive loss of vision. It can also worsen pre-existing eye conditions such as myopia and glaucoma.

 

 

 

 

 

Woman Staring at Her Food

5. Not eating enough food for the eyes

Dark leafy greens contain nutrients like lutein and zeaxanthin, which reduce the risk of macular degeneration and cataracts. Yellow and orange-colored fruits and vegetables are also high in beta carotene, vitamin C, and vitamin E, which are all essential for healthy eyesight. Other food for the eyes include egg, nuts, fatty fish, and other seafood.

6. Not drinking enough water

Dehydration hampers your eyes from producing enough tears, which are essential for nourishment and moisture. Dehydration also causes your eyes to become dry, red, and puffy.

 

 

 

 

 

 

 

A Guy Not Wearing Sunglasses

7. Not wearing sunglasses

Overexposure to the harmful rays of the sun can lead to photokeratitis (sunburn of the front surface of the eye), macular degeneration, cataract, unsightly growths on your eye’s conjunctiva, and cancer of the eyelid. Wear sunglasses with complete UVA/UVB protection even on cloudy days.

 

 

 

 

 

A Woman Reading in the Dark

8. Not using proper lighting

Working in dim light makes it difficult for your eyes to focus and leads to eye fatigue while excessively bright light can cause glare. Make sure your home lighting plan addresses every purpose of your rooms. If you have a home office, for instance, you may need a lamp on the worktable to reduce eyestrain.

 

 

 

 

 

 

 

A Man Smoking

9. Smoking

Smoking is linked to dry eyes and various sight-threatening eye diseases, including macular degeneration, cataract, uveitis, and diabetic retinopathy. Smokers are also four times more likely to go blind compared to non-smokers.

 

 

 

 

 

 

 

Eye Examination

10. Not getting regular eye exams

Regular eye exams can detect vision problems and other eye diseases. They can also determine whether you are at high risk for a particular eye disease. Some eyesight problems, like glaucoma, have no warning signs until there is an irreversible loss of vision. If you have not gotten your vision checked yet, start scheduling your regular eye exams today.

Life Changed By LASIK: Blogger Edition

Bloggers Yuki Tansengco (The Style Cat) and Sab Lee (Jay and Sab Around the World) both had vision problems since childhood. Yuki had an eye grade of -2.5 to -2.75 and relied on prescription glasses while Sab, although reluctant to wearing glasses despite being diagnosed with nearsightedness in grade school, had to wear contact lenses when her eye grade became -3.50. Tired of dealing with the inconveniences of wearing specs and contacts, the two eventually decided to have LASIK at Shinagawa Lasik Center, the world’s leading LASIK eye surgery provider.

 

Now, Yuki and Sab are enjoying the benefits of having perfect vision. Aside from seeing the world clearly without relying on any eyewear, they also have more time and freedom to do activities that need good vision, like reading, doing art, playing sports, and driving. Life-changing indeed!

5 Facts You Need to Know About Astigmatism

They say having Astigmatism is like driving through life with a “warped windshield”. Though there is no known cause for most cases of Astigmatism, it is usually attributed to an imperfection in the shape of the eye, particularly the cornea, which is responsible for most of the eyes ability to “bend light” or focusing most of the light which enters the eye.

Due to the irregular shape, the eye’s ability to focus is inhibited. So images may appear distorted or blurred. Astigmatism is a term commonly known but there are still little known facts about this condition.

  1. Most people have it but don’t know it. Because some mild types of this condition don’t affect vision, most people aren’t aware they have it. It is also more common in young people and women. Astigmatism often occurs in puberty. It may also be present in birth and can increase in intensity through the years.
  2. It can go away. Most people do not experience symptoms nor do they require treatment. But prescription eye glasses or contact lenses have been known to treat Astigmatism in its early stages.
  3. The Diabetic Connection. High blood sugar levels can affect the eye, particularly the shape of the lens, which is responsible for the focusing power of the eye. This is called Diabetic retinopathy and occurs when the tiny blood vessels in the eye are blocked.
  4. Rubbing can cause eye weakening. Commonly seen in people with allergies, chronic vigorous rubbing of the eyes can cause of the cornea and eventually cause increased pressure and and irregular change in the shape of the eye.
  5. Exercising can help. This may seem odd but if you really think about it, our eyes are muscles and so they need to be kept in shape. One helpful exercise is to read and avert your gaze periodically. Start by reading one paragraph then shifting your gaze to a nearby object and then go back to reading. Doing this repeatedly will strengthen your eye muscles and improve your ability to focus.

7 Sight Saving Tips for a Brighter Future

When we think about the future we often focus on securing our lives financially. But there is one aspect we often overlook: eye health. Even though we enjoy clear vision, caring for our eyes doesn’t end at achieving 20/20 vision.

1. Follow the 20-20-20 rule.  We spend most of our lives facing digital screens so it’s easy to suffer from eye strain without meaning to. In order to avoid this, we must make it a habit to follow the 20-20-20 rule: throughout the day, we must take 20 seconds every 20 minutes to look away from our computers at an object 20 feet away.
