Eye health is vital for an individual’s quality of life and daily functionality. The sense of vision plays a fundamental role in perceiving the environment, finding direction, avoiding danger, and establishing social connections. Refractive errors in the eye can reduce visual clarity, significantly affecting both life comfort and work performance. In this context, with the advancement of technology, contact lens treatments have created a revolution both aesthetically and functionally. A contact lens is not only a tool for vision correction but also an important treatment method used in many medical and cosmetic areas. Op. Dr. Diclehan emphasizes the place of contact lens use in modern ophthalmology and notes that this treatment option is highly effective when applied to the right patient profile with conscious usage.
A contact lens is a transparent optical corrective material, usually produced for medical purposes, placed on the corneal surface of the eye. Developed as an alternative to glasses, these lenses are used not only to correct refractive errors but also for protective, therapeutic, and cosmetic purposes. Today, billions of people use contact lenses, and this number continues to grow. Contact lens use is preferred not only for aesthetic reasons but also due to lifestyle requirements. For athletes, artists, individuals with active lifestyles, and employees with intense work schedules, contact lenses provide a more practical and functional solution than glasses.
The idea of contact lenses was first introduced by Leonardo da Vinci in 1508. Da Vinci suggested placing a glass sphere filled with water in front of the eye to change its refractive power. Inspired by this idea, scientists in the 19th century produced the first glass contact lenses. However, these lenses were large, rigid, and uncomfortable, preventing their widespread use. In the mid-20th century, with the development of plastic materials, lighter, more flexible, and user-friendly contact lenses were produced. Today, there are lenses with high oxygen permeability that perfectly adapt to the eye and offer various optical and medical features.
Contact lenses are classified based on usage duration, material structure, type of refractive error, and treatment purpose. The most common types include soft lenses, rigid gas permeable (RGP) lenses, hybrid lenses, scleral lenses, and therapeutic lenses. Each type of contact lens is selected according to the patient’s eye structure and treatment needs. Op. Dr. Diclehan emphasizes that a detailed examination of the eye and an assessment of the patient’s lifestyle habits are essential when selecting the most suitable lens.
Soft contact lenses adapt easily to the eye due to their high water content and provide comfortable use. They are available in daily, weekly, monthly, and yearly models. They are widely used to correct refractive errors and have toric options for conditions such as astigmatism.
Rigid contact lenses sit on the cornea and provide clearer vision. They are particularly preferred for individuals with irregular corneal shapes. Compared to soft lenses, they are longer-lasting and provide sharper vision but have a longer adaptation period.
These lenses have a rigid center and a soft periphery, making them ideal for patients seeking both clear vision and comfort. They are highly successful in special conditions such as keratoconus.
These large-diameter contact lenses rest on the white part of the eye (sclera) instead of the cornea. They are used in conditions such as keratoconus, post-corneal transplant, or severe dry eye. They form a protective layer that completely covers the cornea.
These lenses are used for medical purposes to aid healing of the corneal surface after injuries, ulcers, or surgery. Op. Dr. Diclehan highlights that therapeutic lenses are highly effective in accelerating tissue healing on the eye surface.
Contact lenses have a wide range of applications. They are not limited to correcting refractive errors but are also used in cosmetic, protective, and therapeutic fields. They are preferred for conditions such as myopia, hyperopia, astigmatism, and presbyopia, as well as for corneal irregularities, ocular surface diseases, and aesthetic purposes.
Op. Dr. Diclehan notes that contact lens treatments provide significant comfort advantages, particularly for individuals with active lifestyles.
Eye infections may occur if hygiene rules are not followed. Proper cleaning and storage of lenses are crucial.
Some individuals may develop allergies to the lens material.
This can result from severe infections and may cause permanent vision damage. Sleeping with lenses on significantly increases this risk.
Long-term contact lens use can disrupt the tear film. Artificial tear drops may be needed for support.
Op. Dr. Diclehan emphasizes that all these risks can be minimized with proper usage, regular check-ups, and informed lens selection.
Op. Dr. Diclehan emphasizes that strict adherence to hygiene rules is essential for treatment success and eye health.
These mistakes can lead to serious complications. Corneal infections, in particular, can result in vision loss.
However, conditions such as dry eye, eye infections, severe allergies, and certain systemic diseases may prevent the use of contact lenses. Therefore, evaluation by a specialist is essential.
Op. Dr. Diclehan warns that buying contact lenses without a prescription can seriously harm eye health and that lenses must be tailored to each individual’s eye structure.
The most common problems with contact lens use include dry eyes, redness, infections, and corneal ulcers. These issues usually arise from poor hygiene or improper lens use. Sleeping with lenses on, in particular, reduces corneal oxygenation and can cause significant damage. To prevent harm, proper usage habits must be developed, and lenses should always be used under the supervision of an eye doctor.
Op. Dr. Diclehan stresses that each individual’s eye structure is different and that a detailed evaluation is required before prescribing contact lenses.
With advancing technology, contact lenses are no longer just tools for vision correction but are becoming devices capable of measuring medical data and offering virtual reality experiences through smart lens technology. Prototypes have been developed for lenses that can measure glucose, monitor eye pressure, and deliver medications. These advancements are expected to bring revolutionary changes to ophthalmology in the coming years.
Contact lenses are one of the most comfortable and functional vision correction methods offered by modern medicine. With proper patient selection, informed usage, and regular follow-up by an eye specialist, they deliver highly successful results. However, neglect can lead to serious eye problems. Therefore, contact lens users must be informed, follow hygiene rules strictly, and not skip regular check-ups. Op. Dr. Diclehan emphasizes that contact lens treatment must be personalized, as each patient’s eye structure is unique, and this uniqueness determines the success of the treatment. Protecting eye health not only ensures clear vision but also enhances overall quality of life. For this reason, giving importance to eye health is the key to maintaining a high-quality life for years to come.
