Myopia 近视 Control in California

BT50 glasses (+0.50 blue-light filtered reading glasses) help counteract the impact of blue light on eye health. Prolonged exposure to blue light sources can increase the risk of developing eye disease and health problems, including digital eye strain, macular degeneration, and disrupted sleep cycles.

Children who are already being treated through myopia control methods, such as ortho-k or soft multifocal lenses, typically don’t require glasses to see clearly. However, BT50 glasses may be prescribed to improve the effectiveness of the treatment, particularly for children who frequently engage with near-vision activities and digital screens.

Near-vision work (reading, studying, crafting) and digital screens (computers, e-readers, phones) can, over time, impact myopia development. BT50 glasses can reduce eye strain or eye fatigue caused by close-distance activities and filter harmful blue light emitted by digital screens.

While success with ortho-k lenses is common in children, not all children can tolerate the requirements. Ortho-k involves wearing rigid gas permeable (RGP) contact lenses overnight. Medical researchers have looked for a soft contact lens alternative that exhibits the same therapeutic result.

A soft dual focus or multifocal contact lens can improve vision and slow eye growth. The lens design controls peripheral light in the eye, correctly focusing light on the retina. Compared with traditional or single-vision contact lenses, multifocal lenses can slow myopia progression by about 43%.

Today, several custom-made soft lenses can simulate similar results to ortho-k lenses. For example, MiSight soft contacts are available at Golden Vision Optometry. As soft contact lenses are generally easier to adapt to, it is expected that soft contact lenses for myopia control are likely to overtake ortho-k in popularity.

As with ortho-k lenses, practicing proper visual hygiene and contact lens care is still essential. At Golden Vision Optometry, we aim to combine effective methods with education to help our patients achieve the best possible results.

When most people think of hygiene, they likely think about washing their hands, brushing their teeth, and other crucial cleanliness habits. Visual hygiene, however, considers the various ways we care for our eyes. How we use our eyes can impact our eye health and vision.

Intense vision-based activities can exhaust our visual system. Near-vision work, in particular, is considered a risk factor for developing myopia. Because digital screens are typically held or placed closely, they’re commonly related to many near-vision tasks. Digital screens also make the eyes work harder, leading to digital eye strain.

People experiencing digital eye strain may have multiple symptoms, including blurry vision, headaches, and dry eyes. Practicing good visual hygiene can help protect your eye health and prevent vision problems.

When reading, avoid bringing the material too close to your face. It’s best to maintain a distance of 15–25 inches between reading material and your eyes, including printed books and your phone screen.

Take frequent screen breaks. Incorporating the 20/20/20 rule can be a helpful guideline to get you started. For every 20 minutes of screen time, take a 20-second break and relax your eyes. Look at an object 20 feet away to help reset your focus. When possible, avoid staring at a smartphone or digital screen for an extended period.
