Contact lenses are one of the most convenient ways to correct vision-related problems. It is easily disposable and requires least maintenance. It might have minor side effects in the form of irritations and allergies but it requires least time for adaptability. They help to correct nearsightedness and farsightedness along with astigmatism and age-related vision problems like presbyopia. Following are the benefits and harms of wearing contact lenses.
Positive effects of contact lenses
1. Better vision: Wearing contact lenses improves your vision to a great amount, especially peripheral vision. They are comfortable to wear and can correct both nearsightedness and farsightedness. They can cause discomfort initially but are more effective than glasses. Lenses are also available in bifocals and tints and can be worn for long periods of time.
2. Great for active lifestyle: Glasses can be a hindrance to sports activities and can limit your peripheral vision. Lenses on the other hand are great for an active lifestyle as they require short adaptation period. They are easy to put and take care of and do not require a lot of maintenance on your part as it needs least cleaning.
Risks of wearing contact lenses:
- Dry eyes: Dry eyes are the most common side effects of wearing contact lenses
- Infections: Contact lenses wearers are prone to infection of the cornea called keratitis. It can cause swelling, blurry vision and other problems due to lack of oxygen supply to the cornea.
- Allergic reactions: Allergic reaction to the contact lens solution can affect your vision as it causes inflammation of the eyeballs and redness. It can also cause eyelid inflammation and limit your scope of vision. If you wish to discuss any specific problem, you can consult an ophthalmologist.
Amblyopia is commonly known as 'Lazy Eye'. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to 'see' and develop binocularity, that is the ability to perceive depth (Stereoacuity). This occurs in the first 8 to 10 years of life.
Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions ( adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to 'see' and becomes 'lazy'. This condition is seen in 1-4% of population.
The common causes for dissimilar images or Amblyopia are:
1. Misalignment of the eyes or squint: It is the primary reason for Amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different , resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.
2. Refractive Amblyopia:
- Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5D of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
- High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.
3. Cloudiness in visual system or visual deprivation Amblyopia: Any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to Amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood( drooping of one eyelid, eyelid swelling, patching of one eye).
Treatment for Amblyopia: For treatment of Amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.
Patching or occlusion of the good eye: This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye 'learns to see'. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.
To be effective, treatment should be implement as early as possible , within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.
