RxSight® UV-Protective Glasses: Best Practices and FAQs

You will receive three pairs of RxSight UV-protective glasses immediately after your Light Adjustable Lens™ (LAL®/LAL+®) procedure to wear for protection in different settings. The glasses provide a layer of defense from ultraviolet (UV) light to ensure the stability of your vision adjustments. A special coating on the Light Adjustable Lens, called ActivShield provides additional protection from UV rays.

Many patients have questions about the glasses, such as “If the lens already has UV protection, why do I need glasses?” and “Can I maintain my normal daily activities while wearing them?” Below, you may find the answers to these and other questions as well as gain insights into more best practices with RxSight UV-protective glasses.

How do the RxSight UV-protective glasses work?

All frames of the RxSight UV-protective glasses are made from a transparent thermoplastic polyamide material with good heat and UV resistance. They are fitted with polycarbonate lenses, a strong, lightweight plastic material that is resistant to high impacts. Each pair of glasses offers the same level of UV protection. The glasses should be worn during waking hours until your final lock-in treatment.

  • Tinted glasses: Designed for outdoor wear during daylight hours.
  • Clear glasses: For indoor use with general activities.
  • Clear glasses with a 1.50 D reading add: For indoor use with near work and reading, if needed.

Should I avoid any specific activities while wearing the RxSight UV-protective glasses?

While the RxSight UV-protective glasses provide essential UV protection, they are not safety goggles and should not be used for high-impact activities such as skiing, snowboarding, swimming, snorkeling, or paintball. Be mindful about what activities you perform, as you may need to give your eyes more time to heal before participating. Consult your surgical eye care team before resuming them.

Although you must wear the RxSight UV-protective glasses during waking hours, you can remove them for sleeping and showering unless there is direct sunlight exposure.

Do RxSight UV-protective glasses come in different sizes?

Different sizes are available to ensure a proper fit. Additionally, the RxSight UV-protective glasses may be adjusted for comfort. The side arms can be modified to ensure the glasses fit securely across your forehead and upper cheeks. Each pair of glasses comes with a lanyard for added security. If you find they need to be a different size or adjusted, contact your surgical eye care team to explore available solutions.

Can I use any UV-blocking glasses?

No. The RxSight UV-protective glasses undergo rigorous testing to ensure they provide the necessary protection for the Light Adjustable Lens. RxSight cannot guarantee other UV-blocking glasses offer the same level of protection. To ensure optimal outcomes, only use the glasses your surgical eye care team provides, and use them as instructed.

RxSight UV-protective glasses play a crucial role in your journey to achieving customized vision. By wearing them as directed, you are safeguarding your vision adjustments and maximizing the benefits of the Light Adjustable Lens.

Important Safety Information

Approved use: The Light Adjustable Lens™ (LAL®), Light Adjustable Lens+™ (LAL+®), and Light Delivery Device™ (LDD™) system is approved for patients who have a cataract and need surgery for it, have corneal astigmatism (at least 0.75 diopters) before surgery, and do not have preexisting macular disease. Who should not receive this treatment? The LAL/LAL+ and LDD system should not be used if you are taking medications that may increase your sensitivity to ultraviolet (UV) light; if you are taking a medication that is considered harmful to your retina; if you have a history of herpes eye infection or uncontrollable eye movements (nystagmus); or if you are unable to comply with your doctor’s schedule of LDD light treatments and instructions for wearing special UV-protective glasses for several weeks following cataract surgery. What warnings should I be aware of? Preexisting macular disease and certain eye conditions may increase the risk of complications. Your doctor will determine if you are a good candidate for the LAL/LAL+. If you have any complications during your cataract surgery before the LAL/LAL+ is implanted, you may need to have another intraocular lens (IOL) implanted instead of the LAL/LAL+. What precautions should I be aware of? The safety and effectiveness of the LAL and LDD have not been established in patients with certain preexisting eye conditions or in patients who experience certain complications during cataract surgery. The safety and effectiveness of the LAL+ has not been substantiated in clinical trials. The effect of the LAL+ optical design on quality of vision, contrast sensitivity, and subjective visual disturbances have not been evaluated clinically. You should discuss these issues with your doctor. Following surgery, you must wear the special UV-protective glasses during all waking hours for about 4 to 5 weeks and comply with your doctor’s schedule of LDD light treatments. Failure to wear the UV-protective glasses can result in an unpredicted vision change or loss of vision quality after exposure to UV light, such as from sunlight. This may require a second surgery to remove the LAL/LAL+ from your eye and replace it with another IOL. What are the potential risks? As with any surgical procedure, there are risks associated with cataract surgery and IOL implantation. Please discuss these risks with your doctor. Potential risks associated with LDD light treatments include mild alterations to color perceptions; temporary scratchiness, irritation, or dryness to the front part of your eye; and activation of a previously undiagnosed herpes eye infection. Longer lasting and serious adverse events related to the UV light exposure are possible, but rare. There is a small chance that your vision could be made worse or that you may require additional surgery as a result of a complication.

LAL patients saw nearly as well without glasses (UCDVA) as control patients did with glasses (BCDVA).

The Light Adjustable Lens provides optimized vision for patient satisfaction.2

Light Adjustable Lens patients saw nearly as well without glasses (UCDVA) as control patients did with glasses (BCDVA).

Since the Light Adjustable Lens is a monofocal lens, there is low risk of dysphotopsias caused by splitting light, leading to potentially enhanced vision and patient satisfaction.

LAL patients are approximately two times more likely to achieve 20/20 vision or better without glasses at 6 months.

The Light Adjustable Lens offers LASIK-like accuracy in cataract surgery.2,3

92% of eyes (N = 391) achieved results within 0.50 D of target manifest refraction spherical equivalent (MRSE).

Patients are approximately two times more likely to achieve 20/20 vision or better without glasses at 6 months.

The study was a prospective, controlled, multicenter, 12-month study of 600 patients (ITT population) randomized to receive implantation with the RxSight LAL (N = 403) or a commercially available monofocal IOL (N = 197). Effectiveness analyses included 391 LAL patients and 193 control patients. Primary safety variables included best spectacle-corrected visual acuity (BSCVA) at 6 months and incidence of sight-threatening complications and adverse events. Primary effectiveness variables included percent reduction in manifest cylinder at 6 months, percent mean absolute reduction in MRSE at 6 months, and rotation of meridian of LAL at 6 months. Percent of eyes with an uncorrected visual acuity (UCVA) of 20/20 or better at six months post-operatively compared between the LAL treatment group and the monofocal control group was a secondary endpoint.

The Light Adjustable Lens corrects as low as 0.50 D of astigmatism, which is the lowest level approved to be treated.

The ability to treat 0.50 D of postoperative cylinder makes the Light Adjustable Lens the only IOL in the United States approved to correct this level of vision-altering astigmatism. Astigmatism of as little as 0.50 D can reduce visual acuity by one line, and the impact on dynamic, functional visual acuity and low-contrast acuity is even greater.1
