Back to School – Why Eye Exams are Important for your child!

Summer is almost over and it’s back to school season!

As parents, many of us are busy ensuring our kids are ready and prepared for the new school year; worrying about school supplies, new clothes, and new haircuts. There is always a long list of things to do before school starts. But something that often gets overlooked is getting your child’s eyes examined annually.

Early eye examinations are crucial to make sure children have normal, healthy vision so they can perform better at schoolwork and play. Early identification of a child’s vision problem can be crucial because children often are more responsive to treatment when problems are diagnosed early. Early eye exams also are important because children need the following basic skills related to good eyesight for learning:

  • Near vision
  • Distance vision
  • Binocular (two eyes) coordination
  • Eye movement skills
  • Focusing skills
  • Peripheral awareness
  • Hand-eye coordination

Parents also need to be alert for the presence of vision problems such as ‘crossed’ eyes or ‘lazy’ eye. These conditions can develop at a young age. ‘Crossed’ eyes or strabismus involves one or both eyes turning inward (towards the nose) or outward. Amblyopia, known as ‘lazy’ eye, is a lack of clear vision in one eye, which can’t be fully corrected with eyeglasses. Lazy eye often develops as a result of ‘crossed’ eyes, but may occur without noticeable signs. ‘Lazy’ eye can be treated if caught early.

In addition, parents should watch their child for indication of any delays in development, which may signal the presence of a vision problem. Difficulty with recognition of colors, shapes, letters and numbers can occur if there is a vision problem. Children generally will not voice complaints about their eyes, therefore parents should watch for signs that may indicate a vision problem, including:

  • Sitting close to the TV or holding a book too close
  • Squinting
  • Tilting their head
  • Constant eye rubbing
  • Extreme light sensitivity
  • Poor focusing
  • Poor visual tracking (following an object)
  • Abnormal alignment or movement of the eyes (after 6 months of age)
  • Chronic redness of the eyes
  • Chronic tearing of the eyes
  • A white pupil instead of black

Scheduling Eye Exams for Your Child

If eye problems are suspected during routine physical examinations, a referral should be made to an eye doctor for further evaluation. Eye doctors have specific equipment and training to assist them with spotting potential vision problems in children.

When scheduling an eye exam for your child, choose a time when he or she usually is alert and happy.

 

Glasses and Contacts – Keep these tips in mind for kids who wear glasses:

  • Plastic frames are best for children younger than 2.
  • Let kids pick their own frames.
  • If older kids wear metal frames, make sure they have spring hinges, which are more durable.
  • An elastic strap attached to the glasses will help keep them in place for active youngsters.
  • Kids with severe eye problems may need special lenses called high-index lenses, which are thinner and lighter than plastic lenses.
  • Polycarbonate lenses are best for all kids, especially those who play sports. Polycarbonate is a tough, shatterproof, clear thermoplastic used to make thin, light lenses. However, although they’re very impact-resistant, these lenses scratch more easily than plastic lenses.
  • Your eye doctor can help you decide what type of vision correction is best for your child.

Specialists state that 80% of what your youngster learns in school is taught visually. Untreated vision troubles can put children at a substantial disadvantage. Be certain to arrange that your child has a complete eye exam before school starts.

Selecting Your Best Vision Correction Options

Today technology has evolved to a point where patients either with normal refractive errors such as nearsightedness, farsightedness, astigmatism and presbyopia or those with ocular diseases that require specialized vision correction options such as those with keratoconus all have spectacular alternatives to maximize their visual performance. With the multitude of choices available, how does an individual make the decision which to take advantage of? Well let’s begin by saying that the input from your eye care professional is critically important. You need to be properly educated not only about the various options that are applicable to your individual situation but about the advantages and disadvantages of these options.eye glass fitting vision correction options

Normal Refractive Error Options

Let’s begin by discussing vision correction options available to those with normal refractive errors. Basically stated, these individuals have the ability to utilize spectacles, contact lenses or if they are appropriate candidates, consider the refractive surgical alternatives.

Glasses
Today spectacle lens technology has evolved to the point where exceptional vision quality can be achieved with lens designs that allow for the selection of almost any frame size or shape. Thin lens technologies have enabled those with high prescription powers to not only see amazingly well, but to wear glasses that remain quite thin and attractive even with some of the most extreme prescription powers. Your eye care professional can discuss the various lens material options that best work for your situation. New high index materials are not only thin but are very light weight. A concern for some however can be the significantly higher costs associated with these lens materials. For those who need multifocals, new digital and free form progressive addition lenses (PALs) have dramatically increased the success rates associated with adaptation to PALs.

Contact Lenses
Contact lens alternatives for those with normal refractive errors have also dramatically developed technologically over the past years. Today virtually every patient with normal refractive error is a candidate to wear contact lenses. Developments such as astigmatic contacts, multifocal contacts, and hybrid (rigid center / soft periphery) contact lens designs along with the introduction and the tremendous growth in the use of single use daily disposable contacts has made one form or another of contact lenses something to consider for almost everyone. Today’s CLs are healthier, more comfortable and provide better vision than ever before. CLs have the advantage of superior peripheral vision, more natural vision “sensation” and obvious advantages for demanding physical activities. With contemporary contact lens materials and designs we have successfully addressed issues that limited many people in the past such as concerns of poor comfort due to dryness, contact lens vision instability and contact lens induced complications associated with over-wear and over-use of lenses. Your eye doctor should always present contact lens options to you regardless if you ask or not. So often patients think that they can’t wear contacts, so it does become the responsibility of your doctor to inform and educate you about CL alternatives.

Combination of Glasses and Contact Lenses
So how do you decide if you should be a contact lens wearer or a glasses wearer? Who said you have to? The two vision correction options are not mutually exclusive; in fact they are quite synergistic. All contact lens wearers should have an excellent pair of glasses to use. Contacts may be more cosmetically acceptable to many, they may be much better for various physical activities such as sports, however there are many times when glasses may be preferred such as at the end of a long day of contact lens wear, first thing in the morning before inserting your CLs, or on those days you just don’t want to bother with your CLs or simply prefer the look of your glasses for some situations. Today even the person who predominantly wears glasses can consider part time contact lens wear. Single use daily disposable (DD) CLs are the perfect option for such an individual. DD CLs are now even available in astigmatism and multifocal designs!

Refractive Surgery
Refractive surgery is also developing and is more effective and safer today than ever before. An experienced and skilled eye doctor is in the best position to consult with you in order to determine if you are an excellent candidate for the various refractive surgical options available. Again, having refractive surgery does not always eliminate your need for glasses or contact lenses. Although that would be the optimal outcome, many patients still use glasses and contact lenses after having refractive surgery. Typically the glasses and contact lenses are far less strong and are used significantly less often than prior to surgery. Some patients need them due to complications of surgery while others need them when outcomes did not perfectly correct vision and of course refractive surgery does not stop eyes from changing over the years, so many patients who had successful refractive surgery may experience vision changes years after surgery that require the use of glasses, contacts or both.

Irregular Refractive Error Options

Specialty Contact Lenses
Next let’s talk about choices in vision correction for those with irregular corneas and other conditions that are termed “medically necessary” vision correction cases. Individuals with irregular corneas such as those with keratoconus or post LASIK or other refractive surgery induced ectasias often require contact lenses that in essence “mask” the irregularity of the cornea. In the past this equated with the fitting of rigid corneal contact lenses, however today many other alternatives can be considered such as the fitting of scleral large diameter gas permeable contacts, hybrid CLs designed for irregular corneas and even combination systems of soft lenses with corneal gas permeable lenses (called “tandem” or “piggyback” CL systems). These CL alternatives provide advantages such as improved comfort, improved eye health response by limiting contact lens to cornea bearing, and improved contact lens positioning and stability which positively impacts visual performance.

Combination of Contact Lenses With Glasses
It should be clearly stated that spectacle lens alternatives still can have a significant role in the treatment of individuals with irregular corneas. Often glasses can be prescribed that provide adequate vision if even for part time and limited applications. While less severe cases may perform quite well with glasses as their primary modality of vision correction. Your doctor may need to modify the power of your glasses prescription in order for you to adapt to wearing glasses, however even a modified prescription power can frequently allow for some degree of visual function and allow for the ability to reduce the number of contact lens wearing hours during the day.

Surgical Procedures
Application of certain surgical and medical procedures such as intra-corneal ring segments (Intacs TM) or corneal collagen cross linking (CXL) for corneal irregularity can often help these patients in various ways and may allow for perhaps a less complex contact lens application or easier adaptation and improved function with glasses. Management of these diseases and conditions is quite complex and requires the expertise of doctors with extensive experience. Your doctor, if appropriately skilled and experienced can provide you with all of the required information and education so that you both can jointly decide on the best vision correction options for you.

In conclusion, patients today have numerous options for their vision correction. These options each have advantages and disadvantages but in most cases can be utilized synergistically. The role that your eye care professional plays in consultation and education of the vision correction alternatives applicable to you cannot be over stated. Vision is a precious gift and you should experience the highest quality of visual performance possible.
