Introduction

Parents frequently ask this question whenever their child is advised to wear contact lenses for optical correction. Actually there is no specific age limit to start wearing contact lenses. Contact lenses can be worn at any age as long as the parameters of the cornea can be matched with the curvature and diameter of the lenses. Contact lenses can be prescribed as early as the age of infants, for valid reasons as long as the child’s eyes can tolerate well when wearing contact lenses.

Children who are capable of managing themselves and perform their daily responsibilities well, such as looking after their personal hygiene, are excellent candidates for contact lenses. On the other hand, for children who are not yet ready to look after themselves, it is their parents or guardians’ duty to put on and take off their children’s contact lenses, including the care involved. However, parental concerns about complications, infections and difficulties faced by the child wearing contact lenses cannot be denied.

Scientific research has proven that wearing contact lenses at a very young age gives optimum benefit to the children if everyone involved follows the guidelines for handling contact lenses, as instructed by ophthalmologists or optometrists. In a recent study that involved fitting contact lens in children at age 8-11 with one-day disposable contact lenses, 90 percent of the kids had no trouble applying or removing the contacts without assistance from their parents. Studies have also shown that the incidence of contact lenses complications was low among children aged 8-12 years and most high among users aged 18-25 years by 3.5 times. Plus, younger children sometimes follow instructions about contact lens wear better than teenagers and young adults, so they may have fewer problems with over-wearing their contacts or not using the correct contact lens solutions. Children also have tears of better quality compared to adults, whereby the quality of tears is very important for contact lens wearers.

Refractive error in children from birth till 8 years old should be given priority in correction in order to prevent from dense amblyopia that may have a big impact on them when they grow older. Amblyopia (lazy eye) is a common effect of refractive error which is not corrected at an early stage (refer to amblyopia/lazy eyes article). Contact lens is an alternative to correct refractive errors in both children and adults.

Conditions That Require Children To Wear Contact Lenses

Anisometropia is a different refractive power between the two eyes more than 2.00D. Individuals who suffer from this problem usually feel uncomfortable when using glasses due to binocular imbalance. The use of contact lenses can eliminate the effects of these imbalances and provide better stereo acuity to the patients.

Aphakia is the eye that does not have the crystalline lens. The main causes of blindness in children are presence of paediatric cataracts. Children who are born with cataracts will usually undergo surgical removal of the crystalline lens. If for some reason intraocular lens did not inserted into the baby’s eye, the contact lens become the best optical correction at that time especially for unilateral cataract. Clinical studies designed to compare the visual outcome of children who are pseudophakic with aphakic contact lens corrected, children are failed to exhibit statistically significant difference in visual acuity. Unfortunately in view of child’s physical appearances, if spectacle correction be the first choice after surgery, the child may seem less interesting, strange compared to other children and uncomfortable  because the lens is thick, heavy and have limitation in the field of view. In some circumstances, study has proved that wear a contact lenses often can improve how children feel about their appearance, elevating their self-confidence and also easy to get along with friends.

Contact Lens For Extreme Sport

It is not recommended for players who play contact sports to wear spectacles. The use of soft contact lenses along with other protective eyewear permitted during sport is more practical and safer.

Among the advantages of using contact lenses during sports are:

• There are no obstacles in the visual field of players by spectacle frames and give wider peripheral vision.
• The uses of glasses lens easily get misty due to climate change and the environment, such as rain. Sometimes can fog up during competition, affecting vision and performance.
• Low risk to get eye injury.
• Give better and stable vision with heavy movement such as running.
• Improving self-confidence and more competitive players during sports.
• There are also have customized contact lenses for players who need protection from ultraviolet radiation from sunlight like outdoor sport.

Uneven Cornea like keratoconus or children who underwent corneal transplants and so on may contribute to an irregular astigmatism and will lead to reduction in vision and glare. Semi- hard types of contact lenses are very suitable for this problem.

Controlling Myopia

Myopia is one of the refractive errors which the child will have blurring of vision at distance. The severity of myopia is depending on eye power.  The myopia have tendency to increase in children until reaching a certain age. Various approaches have recently been suggested including orthokeratology lenses specifically designed to control myopia. Studies conducted at the University of Ohio and the Polytechnic University of Hong Kong found that the decline in the power of the eye for people with myopia when using orthokeratology lens which is a lens that is used during sleep. Furthermore these approaches, and the size of the effect, need to be supported by large-scale, long-term studies.

Cosmetic

Children as well as adults have potential to get such as scarring of the cornea, aniridia (absence of the iris) and heterochromia (iris color differs both eyes) which cause physical inequality in both eyes. This can make the child embarrassment and loss of self-confidence. Therefore prosthetic contact lenses can be used for the purpose of closing the defect on the eyes so that their physical appearance are more attractive as well as enhancing their self-confidence to deal with the public
