From the first greeting to the follow up, we believe that each patient deserves the very best experience from the optometrist, optical, and staff. Vision is such a fundamental element of who we are and how we experience life. We take our responsibility very seriously.

We specialize in contact lenses for patients who experience discomfort and dry eyes from contact lenses. Depending on the reason for your discomfort our Optometrist Dr. Galan will recommend one of two options for dry eyes. The first option is daily disposables such as Dailies Total 1 which prevent irritating deposit build up, are ultra breathable, and integrate hydrating components into the design. The second option is Sceral Lenses, which retain moisture due to their unique design and reservoir.


Multifocal contact lenses are a great option for patients with Presbyopia. Presbyopia is an element of aging usually occurring in the late 40’s which makes seeing close difficult. We tend to associate Presbyopia with reading glasses, however multifocal contacts offer a built in solution which utilizes different powers in different parts of the lens to allow you to effortlessly switch back and forth from close, medium, and far tasks. Multifocal contacts are available in soft and rigid gas permeable options.


Our contact lens center offers patients a wide variety of contact lenses for your needs. Toric, RGP, GP, OrthoK, Hybrid, Piggy back and more options are available. After your contact lens eye exam Dr. Galan will talk with you about the options that are best suited for your particular needs. Depending on the situation there may be more than one option that is a good fit and Dr. Galan will explain the benefits and weaknesses of each option. Elements to consider are comfort, breath-ability, clarity of vision, ease of use, and ease of care.

Watch Our Video On Scleral Lenses



Keratoconus is a condition that can develop in the pre-teen years when the cornea starts to change its shape. Associated with these changes are extreme sensitivity to light or glare, blurry vision (like being unable to view the blackboard), and sudden decreases in vision. To get a better picture of Keratoconus, imagine that the top white surface of an eye having lots of ridges and bumps that would prevent a regular contact lens to rest on and adhere to the eye surface. These surface variations are unique to each individual, where some may be able to get by with contacts or glasses, while for others, hard lenses or scleral lenses are the preferred alternative.

Because of the irregular shape of the cornea, it is extremely important that a person with Keratoconus has accurate measurements including both a 3D map of the corneal and the thickness.

The Challenge Of Keratoconus

The real challenge for patients with Keratoconus isn’t from a lack of alternatives but the constant change in prescriptions nearly every year. In certain cases of Keratoconus, the changes become so extreme that people turn to Corneal transplants.

For those living with Keratoconus, finding a knowledgeable and reliable optometrist with the latest technology is essential, especially since there are solutions for visual comfort that may come up short. Dr. Shane Galan at Diamond Vision has been fitting scleral lenses for Keratoconus patients, providing the desired comfort and clarity that’s not found anywhere else. People often visit Dr. Galan for a second opinion about their Keratoconus or irregular corneas just to be sure that their current prescription is accurate.

Options For Patients With Keratoconus

While hybrid contact lenses supply better quality of vision for irregular shaped eyes, the hard components used may not provide comfort for some. Patients could turn to scleral lenses, which are large gas permeable contact lenses that cover the entire corneal surface of the eye, ensuring greater comfort.

Fortunately, at Diamond Vision, Dr. Galan provides a variety of specialty contact lens treatments that can be custom tailored for nearly any case of Keratoconus, irregular shaped corneas, or extreme astigmatisms. Through years of experience and a knowledgeable, caring staff, there’s no other optometry practice that has the commitment to expertise, patient care, and consistent, successful outcomes. To receive the best fit possible for your eyes, schedule a consultation with us today.

the latest in contact lens technology zen lens scleral lenses fitted by our eye doctor in Nassau County Long Island

Zen lens scleral lens contacts in long island NY

We are proud to offer Zenlens™ scleral lenses in our Rockville Centre Long Island practice. Scleral lenses in general have made massive inroads into the contact lens market as they offer some very important benefits over traditional contact lens technology. Scleral lenses vault over the eye and sit on the white part, or the sclera of the eye. This design is superior for three reasons.

  1. The vault design means that patients with irregular shaped corneas from Keratoconus, corneal scarring, or post surgery have an option that both corrects vision more effectively and increases comfort.
  2. The vault design is a drastic improvement for patients with dry eyes, as the vault creates a reservoir for tears to naturally maintain lubrication.
  3. Scleral lenses large design minimizes movement which means less irritation from movement in the eye and sharper vision.
