When you put on your scleral lenses in the morning, it's like putting on a new set of eyes. The solution with which you fill your scleral lenses conditions your eye all day long, alleviating the sensation of dryness. Your vision is dialed in to near-perfection. The blur, distortion, or glare from your high prescription, astigmatism, keratoconus, or LASIK/RK is diminished. 


If you are thinking that your current level of vision and comfort is lacking with your glasses or contacts, don't settle. Our scleral lenses represent the most advanced form of visual correction and we'd love for you to experience effortless day to day vision. 


Who is a candidate for scleral lenses?
  • Patients with corneal degenerative diseases such as keratoconus or pellucid marginal degeneration

  • Patients with higher prescriptions whose visual needs aren’t met by glasses or soft contacts

  • Patients who suffer from dry eyes with or without soft contacts

  • Patients who suffer from glare/distortion after LASIK, PRK, or corneal transplants

  • Patients who have exacting visual demands (sports, videography, photography)

What exactly are scleral lenses?

Scleral lenses are large diameter lenses that create a moisture chamber over the cornea (the clear window of the eye) and gently rest on the sclera (the white, outer layer of the eye). Vision is extremely crisp due to the rigid nature of the lens. Sclerals should not be confused with traditional RGP lenses. Traditional RGP lenses are small, rigid lenses that sit on the extremely-sensitive cornea. Most patients find traditional RGP lenses to be very uncomfortable. Alternatively, scleral lenses are created for comfort because they settle on the less-sensitive sclera instead of the highly-sensitized cornea.

Will I see a difference between scleral lenses and soft contact lenses?

Scleral lenses are built from highly-customizable lens materials that offer the clearest and most stable vision correction relative to soft lenses. For example, consider how vision is better through a window versus clear, flexible plastic sheeting. Scleral lens prescriptions are inherently more stable due to how the rest on the eye. Lastly, scleral lenses are more customizable for full distance clarity or for improved reading vision (with the option for tuned multifocals or monovision).

Do all eye doctors fit scleral lenses?

Not all eye doctors fit scleral lenses. At Lumen Optometric, we specialize in advanced scleral fitting, what we coined as “Scleral 2.0” lenses. Our Scleral 2.0 lenses are created from a custom scan of the entire frontal aspect of your eye. This scan is captured with the sMap3D, which is an instrument that is dedicated only to scleral lens mapping. With this technology, we capture a full 3D representation of your frontal eye so that we can build a lens that is most accurate. We are the only provider in the San Gabriel Valley to offer this state-of-the-art technology. We liken it to building a 100% bespoke suit from scratch after taking every single possible measurement of your body.





















Traditional sclerals, what we call “Scleral 1.0” lenses, have been used for roughly a decade. Fitting Scleral 1.0 lenses is similar to modifying an off-the-rack suit. Traditionally, you select a suit size that approximates your body shape and make a limited number of adjustments to help the suit to drape your body’s contours. Our mission at Lumen Optometric is to aim for a flawless fit with your scleral lenses, not a best-guess approximation.

















If I have keratoconus, pellucid marginal degeneration, or any other condition where the cornea is no longer regular or consistent in its shape (post-LASIK/RK/corneal transplant), how will sclerals help me?

In short, it will give you clearer, distortion-free vision. The long answer: Think of an irregular cornea as a windshield of a car that is warped. With a warped windshield, vision through that windshield is distorted. Lights are stretched/distorted, vision is blurry, etc. When you fill a custom scleral lens with conditioning solution and apply it to your eye, the solution "mates" the scleral with your cornea, giving you a new smooth, regular surface to work with. This perfectly contoured surface cancels out your distortion and blur, leaving you with clear, comfortable vision.

If I’m already wearing glasses/contacts and I see fine, will scleral lenses make a difference?

The answer depends on a few factors:

  1. Define “fine.” Most people are fairly adaptable to the options that they are given. Until you are shown a difference, you may not be aware that potential for improvement exists. For example, if you have been wearing the same set/brand of contacts for nearly a decade (like most patients out there), there is a good chance that there is clearer, healthier, and more comfortable technology that you may not be aware of. Our doctors are not interested in making your year to year visits routine, we intend to keep you up to date with the best and healthiest options for your only set of eyes.

  2. Your prescription. If you have an extremely minimal prescription, scleral lenses will help more with dry eyes or performance-based vision (sports, videography, photography). If you have a moderate or high prescription with astigmatism, the benefits of sclerals will be much more apparent. Vision will be clearer and most importantly, more stable. Visual stability is something that many of us take for granted until we are shown what true stability looks like for the first time. For example, consider the fluidity of the newer 120hz televisions relative to their older 60hz counterparts. 60hz televisions looked normal to us until 120hz was released. When patients have high levels of astigmatism, the result will be similar to that of the television example.

  3. Your corneal health. For patients with any corneal issues (see question #1), scleral lenses will significantly impact your vision and improve your quality
    of life.


If my eyes are dry, how can sclerals help me?

When you apply a scleral lens to your eye, the “bowl” of the lens is filled with sterile conditioning solution. This conditioning solution is held against your eye for as long as you wear the lens, creating a “moisture chamber.” This moisture chamber is what will help alleviate your dry eye. Keep in mind that scleral lenses represent only one treatment modality within a greater dry eye treatment system. Some severely chronic dry eye patients may need additional treatments to overcome their dryness symptoms.

What’s it like to be fit with “Scleral 2.0” lenses?

An advanced scleral lens fitting starts with scleral topography, which requires an instrument dedicated to scanning the elevation changes of the white surface of your eye. This painless procedure does not require dilation drops, but it will require the use of a temporary dye that will enhance our scans. We then place a calibrated “test” scleral lens on your eye to fine-tune your prescription. Once your prescription data is obtained, it is combined with the shape data from the dedicated instrument to create your fully-customized scleral lens.


Traditional “Scleral 1.0” lenses are fit only with test lenses that are calibrated by “eyeballing it.” The 2.0 method saves the patient much more time by reducing the number of alterations that have to be made.


During a scleral lens consultation, you will have the opportunity to wear and see through a "test" scleral lens. Please keep in mind that we take all of our measurements of your eye at the initial fitting, so we set aside 90 minutes of doctor time to ensure that the measurements are correct.
