Should You Choose Full Prescription or Reduce by 50 Degrees for Glasses? - Ophthalmology

When it comes to choosing the right prescription for glasses, the decision between using a full prescription or reducing the prescription by a certain degree, such as 50 degrees, is a nuanced one that depends on individual circumstances, including the specific visual needs and lifestyle of the wearer.


Understanding the Prescription
In your case, you have a prescription of R775-125 and L575-125. This indicates that your right eye has a significant degree of myopia (nearsightedness) and astigmatism, while your left eye has a lower degree of myopia and the same level of astigmatism. The question of whether to reduce the prescription by 50 degrees is particularly relevant for those who spend a lot of time doing close-up work, such as reading or using a computer.


Benefits of Reducing the Prescription
1. Reduced Eye Strain: Reducing the prescription can help alleviate eye strain, especially if you are primarily engaged in near-vision tasks. A lower prescription may allow your eyes to relax more, potentially reducing fatigue during prolonged periods of close work.

2. Comfort: Some individuals find that a slightly lower prescription is more comfortable for daily activities, especially if they are not accustomed to wearing glasses. This can be particularly true for those who have recently started wearing corrective lenses.

3. Avoiding Over-Correction: Over-correcting can lead to discomfort and may cause the eyes to work harder than necessary, which can exacerbate issues like astigmatism or lead to headaches.


Risks of Reducing the Prescription
1. Blurriness at Distance: While reducing the prescription may help with near tasks, it can lead to blurred vision at a distance. This is particularly important if you need to see clearly while driving or in other situations where distance vision is crucial.

2. Potential for Worsening Vision: There is a concern that consistently wearing a reduced prescription could lead to a reliance on that lower correction, potentially resulting in a gradual worsening of your vision over time. This is particularly true if you find yourself squinting or straining to see clearly.

3. Imbalance Between Eyes: If one eye is corrected fully while the other is reduced, it could lead to an imbalance in vision between the two eyes, which may cause discomfort or visual disturbances.


Recommendations
1. Consultation with an Eye Care Professional: It is essential to have a thorough discussion with your eye care provider about your specific visual needs, lifestyle, and any symptoms you may be experiencing. They can provide personalized recommendations based on a comprehensive eye examination.

2. Trial Period: If you and your eye care provider decide to try a reduced prescription, consider doing so on a trial basis. Monitor how your eyes feel during different activities and whether you experience any discomfort or changes in vision.

3. Regular Eye Exams: Regular check-ups are crucial to monitor your vision and make adjustments to your prescription as needed. This is especially important if you notice any changes in your vision or if you experience discomfort.

4. Consider Different Lenses: Depending on your activities, you might benefit from multifocal or progressive lenses that can provide clear vision at multiple distances without the need for multiple pairs of glasses.

In conclusion, whether to choose a full prescription or reduce it by 50 degrees is a decision that should be made with careful consideration and professional guidance. Balancing comfort, clarity, and the long-term health of your vision is key to making the right choice for your eyewear.
