If your child is nearsighted, you are probably wondering if there is anything you can do to prevent or help slow nearsighted progression so your child will not need stronger glasses year after year. This is a common question that parents ask in our exam room.

At BVO, we strongly believe in implementing myopia control early on to prevent your child from developing higher levels of nearsightedness (myopia). Moderate to high levels of nearsightedness is associated with serious eye problems and disease later on in life such as early cataracts, glaucoma, and retinal detachment.

Currently, studies have shown four effective ways to control or slow down  nearsighted progression:

• Orthokeratology (“ortho-k”) over-night contact lenses
• Multifocal contact lenses
• Multifocal eyeglasses
• Atropine eye drops

Orthokeratology (“Ortho-K”)

Orthokeratology uses a specially designed hard (gas permeable) contact lenses that are worn during sleep at night to reshape and mold the cornea. By reshaping the cornea to a desired pattern, your child’s nearsighted will be temporarily corrected so he/she won’t need to wear glasses during the daytime. Several research studies around the world have proved that orthokeratology therapy help prevent or slow down nearsighted progression.

Multifocal Contact Lenses

Special multifocal contact lenses can be used to control or slow down nearsighted progression.  Multifocal contact lenses contain different prescriptions across the contact lenses compared to regular contact lenses that only have one prescription all across. The center zone of the multifocal contact lenses helps correct the full amount of nearsighted while the outer zones contain weaker prescriptions. The outer zone areas with the weaker prescriptions help relax your child’s eyes when they are doing near tasks such as reading, doing homework, playing on the iPad or the cell phone.

Multifocal Eyeglasses

Similarly to multifocal contact lenses, multifocal eyeglasses contain the different prescriptions from top to bottom. The top portion of the lens contains the full prescription and the prescription gets weaker gradually towards the bottom. When your child is doing near work and looking through the bottom of the lenses, he/she won’t have to focus (accommodate) as much. 

Atropine Eye Drops

Atropine eye drops dilate the pupil and temporarily paralyze the focusing muscle of the eyes. The eye’s focusing mechanism is completely relaxed with the use of atropine eye drops.  Atropine is not used as a first choice of method to control myopia due to the eye drop’s potential side effects: light sensitivity and blurred near vision.   

A lot of parents have asked our doctors to under-correct or prescribe less nearsightedness prescription so their children’s nearsightedness will not grow faster. It is worth noting that under-correction of nearsightedness is ineffective at slowing myopia down.  Under-correction of spectacle lenses also makes your child’s distance vision blurry, which puts your child at a disadvantage in the classroom and in life. More recently, studies have shown that more outdoor time may also reduce myopia progression. There are many ways to control myopia as discussed above, we highly recommend controlling your child’s nearsightedness as early as possible to prevent higher eye health risk in the future.

About BVO Eats! — Every quarter, eBVO Eats! will feature a restaurant in Chino Hills and highlight a spotlight dish. The purpose is not to provide a comprehensive review, but to introduce our readers to some of our favorite eateries in this wonderful city. We love exploring our local community — what better way of doing this than eating?

In our last post, we discussed the new technology of digital lenses for high-definition vision. Today, we will discuss the different glasses lens materials available. 

There are many different types of glasses lens materials and coatings that we can proudly fit for you. Depending on your prescription, vision needs and preference, we can help select the perfect lens for your eyes. Here are the different glasses lens materials:

CR-39: This regular plastic lens is the foundation of the lens family. It is about half the weight of glass, and because of its low cost, is often considered a desired lens.

Polycarbonate: Polycarbonate is both light weight and up to 10 times more impact-resistant than CR-39 lenses. They also provide 100% protection from the sun’s harmful UV rays. Polycarbonate lens is recommended for all ages, but required for children under the age of 18.

Trivex: Trivex is similar to polycarbonate — it is thin, impact-resistant, and light weight. For patients with a mid to high prescription, we highly recommend this type of lens so it will be much more aesthetically pleasing, as it helps thin the lens even more than polycarbonate lenses. Compared with polycarbonate, trivex provides sharper optics and less distortion. 

High-Index: For patients with even higher prescription, and who might be more self-conscious about how thick their lenses are, this lens is for you! We highly recommend this type of lens so it will be more aesthetically pleasing, while still providing the comfort of even thinner lenses. This lens is the thinnest of them all!

Here is a breakdown of some lens material and coating terms:
