Some individuals may feel self-conscious about their appearance while wearing glasses, which can affect their self-esteem or confidence.
Peripheral Vision Distortion
The frames of glasses can obstruct peripheral vision, leading to reduced awareness of objects or movement on the sides.
Glasses can fog up in cold or humid environments, making it difficult to see clearly.
Limited Sports and Activities
Glasses may be inconvenient or unsafe during certain physical activities or sports due to the risk of breakage or discomfort.
Dependence on Glasses
Regular use of glasses can create a dependency, making it challenging to function without them, especially in situations where glasses might not be available.
Glasses can cause discomfort or pressure on the nose and behind the ears, especially if not fitted properly.
Inconvenience with Rain or Sweat
Raindrops or sweat on glasses can obstruct vision and require frequent cleaning.
Limitation in Some Professions
Certain professions or job roles that require specialized eyewear (e.g., safety goggles) may be less compatible with wearing glasses.
Reflections and Glare
Glasses lenses can reflect light or glare from various sources, causing visual discomfort, especially in bright environments.
Some individuals may experience an adjustment period when they start wearing glasses, during which they might need time to get used to the altered vision and the feel of the glasses.
Misplacement and Breakage
Glasses can be easily misplaced, and there’s a risk of breakage, which can result in the inconvenience of obtaining replacements.
It's important to note that many of these disadvantages can be mitigated or minimized by choosing appropriate frame styles, lenses with anti-reflective coatings, and proper care and maintenance of glasses. However with the recent advances we have the option to have clear vision without needing to wear glasses. Various options are available which can address people of different age group.
Children and young adults(Up to the age of 18 years)
In this age group, the focus of treatment is prevention. With the growing prevalence of myopia (nearsightedness) among children, it’s essential to understand how we can take proactive steps to prevent its onset and manage its progression.
Here's what you need to know:
Myopia is a common refractive error where distant objects appear blurry while close-up objects can be seen clearly. It typically develops during childhood and tends to worsen as a child grows. Genetics play a role, but environmental factors also contribute significantly.
PreventiveICAL PROCED Measures:
- Outdoor Time: Encourage your child to spend more time outdoors. Studies suggest that natural light and outdoor activities play a crucial role in preventing myopia onset and progression.
- Screen Time and Reading Habits: Keep a balanced approach to screen time and reading. Encourage breaks every 20 minutes when using digital devices or reading. The 20-20-20 rule is helpful: every 20 minutes, look at something 20 feet away for at least 20 seconds.
- Proper Lighting: Ensure adequate lighting when your child is reading or using digital devices. Poor lighting can strain the eyes and contribute to myopia progression.
- Distance from Screens: Encourage your child to maintain a healthy distance from screens. The screen should be at least an arm’s length away from their eyes.
- Nutrition: A well-balanced diet rich in vitamins and nutrients, particularly vitamin A, C, and E, can support eye health. Include foods like carrots, spinach, oranges, and eggs in their diet.
- Hydration: Proper hydration is vital for overall health, including eye health. Make sure your child drinks an adequate amount of water throughout the day.
- Regular Eye Check-ups: Schedule regular eye check-ups with ophthalmologist. Early detection and intervention can prevent severe myopia and related complications.
- Proper Workspace Setup: If your child is studying or using a computer, ensure their workspace is ergonomically designed. The screen should be at eye level, and the chair and desk should support good posture.
- Appropriate Eyewear: If your child already wears glasses or contact lenses, make sure they wear them as prescribed. Incorrect prescriptions can contribute to myopia progression.
Setting a Healthy Example:
Children often mimic their parents’ habits. Show them the importance of following these practices by incorporating them into your daily routine as well.
In recent years, there have been exciting developments in the field of ophthalmology regarding the treatment and prevention of myopia progression in children. These newer modalities offer additional options alongside traditional methods. Here are some of the emerging treatments:
- Orthokeratology (Ortho-K): Ortho-K involves using specially designed rigid contact lenses that reshape the cornea while the child sleeps. Upon waking up, they remove the lenses, and the reshaped cornea allows for clear vision throughout the day. This method has shown promise in slowing down the progression of myopia.
- Low-Dose Atropine Eye Drops: Low-dose atropine eye drops have gained attention for their effectiveness in slowing down myopia progression. Atropine is a medication that dilates the pupil and temporarily relaxes the focusing mechanism of the eye. Low concentrations of atropine are used to minimize side effects while still providing benefits in reducing the rate of myopia progression.
- Customized Spectacle Lenses: Customized spectacle lenses use advanced optical designs to provide clear central vision while simultaneously altering the peripheral optical profile. This approach aims to provide clearer peripheral vision, which might influence the eye’s growth and slow down myopia progression.
It’s important to note that the suitability of these treatments varies from case to case. An eye care professional can evaluate your child’s specific condition and recommend the most appropriate treatment plan based on their individual needs. Regular follow-ups and professional guidance are essential to monitor progress and adjust treatments as necessary.
Adults (18 -37 years)
- Corneal Refractive Surgery: For individuals with stable vision and appropriate age, refractive surgery options like LASIK (Laser-Assisted in Situ Keratomileusis) or PRK (Photorefractive Keratectomy) can be considered. These surgeries reshape the cornea to correct refractive errors, often eliminating the need for glasses or contacts.
- Phakic IOLs – For individuals who have very high spectacle power ( greater than -10 D), a very thins is implanted within the eye just infront of natural crystalline lens. This can take care of spectacle power upto -20 D. Phakic IOL is also a treatment of choice for smaller spectacle powers in whom laser refractive surgery cannot be done as in case of thin or abnormal shaped cornes.
- Refractive Lens Exchange: This is a procedure reserved for very high plus number glasses where in natural crystalline lens is replaced by intraocular lens
Middle aged and Older Individuals (More than 40 years of age)
Individuals over the age of 40 years with glasses for both distance and near can opt for presbyopic lens exchange ( PRELEX) where in normal crystalline lens is replaced by presbyopia correcting IOLs. These IOLs can also be used during cataract surgery to reduce spectacle dependence.
Presbyopia-correcting intraocular lenses (IOLs) are designed to address the natural age-related loss of near vision that occurs around the age of 40. These lenses provide a range of vision, reducing or eliminating the need for reading glasses or bifocals after cataract surgery or lens replacement. There are several popular types of presbyopia-correcting IOLs, each with its own advantages and limitations. Here are some of the most well-known options:
- Multifocal IOLs:
- Provide clear vision at multiple distances, including near, intermediate, and distance.
- Reduce or eliminate the need for reading glasses or bifocals.
- Good overall vision for various activities without switching glasses.
- Some patients may experience halos, glare, or reduced contrast sensitivity, especially in low-light conditions.
- Adaptation period may be required to get used to the different focal points.
- Not all individuals are suitable candidates due to certain eye conditions.
- Extended Depth of Focus (EDOF) IOLs:
- Provide an extended range of clear vision, including intermediate and some near vision.
- Minimize visual disturbances like halos and glare compared to traditional multifocal IOLs.
- Smooth transition between different distances of vision.
- May not provide as distinct near vision as multifocal IOLs.
- Some patients might still require reading glasses for very close tasks.
It’s important to consider that each individual’s visual needs and preferences are unique. The choice of a presbyopia-correcting IOL should be made in consultation with an experienced ophthalmologist, who can evaluate your eye health, lifestyle, and expectations to determine the most suitable option. It’s also important to manage expectations, as while these IOLs can significantly reduce dependence on reading glasses, they might not provide the exact same vision as natural lenses for all activities.
