Selecting a new pair of eyeglasses can be a daunting task, but the importance of choosing the right pair goes far beyond the frame selection.  The most important part of your glasses are of course the lenses, but different lens materials can make the difference between seeing well and struggling with your new prescription.  The most popular lens material is CR39 plastic.  This lens material is relatively safe (for impact resistance), has great optic characteristics, and fits most budgets.  Polycarbonate lenses are also widely used and boast impact resistance as their top quality.  The optics can be a little less sharp than CR39, but in most cases the wearer has no issues.  Polycarbonate lenses can be ground a little thinner, which helps to reduce overall lens thickness and the weight of the glasses. 

 

For those eyeglass wearers with a strong prescription, Hi-index lenses may be the best option.  They allow for the thinnest finished lenses and great optics, but they are softer than the other materials and can scratch easily.  Hi-index lenses should always be paired with a good scratch coat or an anti-reflective coating that acts dually as a scratch guard.  Trivex is another material that is sometimes used for eyeglass lenses.  It’s an impact resistant lens material with slightly better optical clarity than polycarbonate lenses, but the availability is limited and may not be an option for your particular prescription.  

 

Older eyeglass wearers will often inquire about glass lenses.  However, they are harder to scratch and up until recently they were the most used lenses for eyeglasses.  They are no longer a viable option.  They are not safe, because they can shatter, and the availability is extremely limited.  Even if available, expect pricing to be double or triple that of more advanced lens materials.

 

When selecting your new glasses, make sure to ask about what lens material works best for your prescription.  While frame styles are important, what you put inside of them will make all the difference.  Your local optician or our professionals at Darrell M. Sipe Opticians and Hearing Aids can assist you today!

How to Proactively Monitor Your Eyes for Glaucoma

When we age, taking care of our health becomes increasingly important. One area that deserves special attention is our vision, particularly the risk of developing glaucoma. Glaucoma is an eye condition that can lead to irreversible vision loss if not detected and managed early. For seniors with diabetes, monitoring eye health becomes even more necessary, as diabetes can increase the risk of developing conditions like glaucoma. Being proactive about eye health can make a significant difference in maintaining good vision for years to come.The Link Between Diabetes and GlaucomaDiabetes can cause various health problems, including those affecting the eyes. High blood sugar levels can damage the small blood vessels in the eyes, leading to conditions like diabetic retinopathy and glaucoma. Seniors with diabetes are at a higher risk for these eye problems, making it essential to keep a close eye on eye health.How Glaucoma Affects VisionGlaucoma is a progressive disease that affects the optic nerve in the eye. Over time, it can lead to a gradual loss of vision, often starting with peripheral (side) vision. As the condition progresses, it may lead to tunnel vision or even complete blindness if left untreated. Early on, glaucoma may not present any noticeable symptoms, which is why regular eye exams are vital. Signs to watch for include blurred vision, halos around lights, or loss of peripheral vision.Early Warning Signs of Deteriorating Eye HealthRecognizing the early warning signs of glaucoma and other eye conditions is necessary for seniors, especially those managing diabetes. Here are some signs to be on the lookout for:Sudden or gradual loss of peripheral visionSeeing halos or rainbows around lightsEye pain or rednessBlurred visionHeadaches or eye discomfortEarly detection allows for better management of the condition, potentially preserving vision.Why You Need Regular Eye ExamsRegular eye exams play a key role in detecting glaucoma early. Eye doctors can perform tests to measure intraocular pressure and examine the optic nerve, helping to identify signs of glaucoma. Seniors should aim to have a comprehensive eye exam at least once a year or more often if recommended by their doctor. Staying vigilant with eye exams ensures that any changes in vision can be addressed promptly.Tips for Proactively Monitoring Eye Health at HomeIn addition to regular eye exams, there are practical steps seniors can take at home to monitor their eye health. Using good lighting when reading or performing activities can help reduce eye strain. Wearing sunglasses outdoors protects against harmful UV rays that can damage the eyes over time. You need to pay attention to any changes in vision and note them down for discussion with an eye care professional. Some seniors find it helpful to use tools like an Amsler grid to regularly check for vision distortion. Protect Your EyesProactively monitoring your eyes for glaucoma is a necessary part of maintaining overall health, particularly for seniors with diabetes. Understanding the relationship between diabetes and eye health and recognizing early warning signs of conditions like glaucoma can make a big difference. By scheduling regular eye exams and taking steps to monitor vision at home, seniors can protect their eyesight and enjoy their golden years with clarity.

Supporting Seniors Coping with Vision Loss

It's common for our vision to change with age. For many seniors, these changes can lead to significant vision loss, making everyday tasks challenging. Family members and caregivers can provide vital support that helps seniors cope with these challenges.Encouraging Open CommunicationTalking about vision loss can be uncomfortable, but it must be addressed openly. Start by gently asking the senior about any changes they've noticed in their eyesight. Let them share their experiences and fears.  Listen actively. Pay attention to what they are saying without interrupting. In addition, validate their feelings. Let them know that it's okay to feel sad, angry, or frustrated about their vision loss.Providing Emotional SupportVision loss can be emotionally overwhelming. It's normal for someone to feel stressed or depressed about losing their sight. Recognizing these feelings and offering empathy is essential. Show understanding. Explain that their emotions are a normal reaction to vision loss and let them know that you're listening. If needed, encourage professional help. Suggesting counseling can sometimes help seniors manage their feelings better.By being there emotionally, you can help alleviate some of the mental stress associated with vision loss.Helping Seniors Engage in Meaningful ActivitiesStaying engaged in hobbies and activities can greatly enhance a senior's quality of life. However, activities must be adapted to accommodate vision loss. Look for ways to adapt to current hobbies. For instance, if they enjoy reading, consider audiobooks or large-print books.As your loved one's vision changes, try to introduce new, vision-friendly activities. Gardening, music, or board games designed for low-vision individuals can be fulfilling. Use technology and assistive devices as needed. Devices like talking clocks, magnifiers, and screen readers can help them continue to enjoy activities they love.Resources for Support Groups and Counseling ServicesFinding support outside of family can also make a big difference. Local and national resources are available for seniors coping with vision loss. Organizations such as the American Foundation for the Blind and VisionAware provide online support and resources.Local support groups can also be incredibly valuable. These groups can offer a sense of community and shared experiences, making it easier for seniors to cope.The Importance of Self-Care for CaregiversCaring for a senior with vision loss can be demanding. Recognizing caregiver burnout and taking steps to care for oneself is vital. Watch for burnout signs. Emotional exhaustion, frustration, and feeling overwhelmed are common signs. Regular exercise, hobbies, and time with friends can help maintain your emotional and physical health.Don't hesitate to ask for help or hire professional respite care when needed! Taking care of your own health ensures you can continue to provide the best support for your loved one.Professional Care for Seniors with Vision LossSupporting seniors with vision loss involves open communication, emotional support, and helping them stay engaged in meaningful activities.
