They say that the eyes are the window to the soul, and it turns out that they—whoever “they” really are—spoke some truth in the saying. You may have noticed that your vision is deteriorating, likely due to the incessant use of your desktop and mobile devices. With a higher prescription often comes a thicker frame, and everyone is on the search for the cheapest 1.74 high index lenses to offset this issue. As a general rule of thumb, the higher the index, the less they weigh. 1.74 weighs the most with a specific gravity of 1.47. Since less lens material is needed to manufacture this lens, the overall weight of the lens is significantly less compared to other materials with the same refractive power (diopters). 1.74 high index lenses are the only lenses on the market that naturally includes an anti-reflection percentage. The percentage is 0.5% reflectance whereas other materials like high index plastics have a higher rate of reflectance. Plastics like CR-39 reflects 7.7% of all light. High index lenses, compared to CR-39, also 100% block UVA & UVB. 1.74 reflects 13.6% of all light. Because of this, higher index lenses should have Anti-Reflective (A/R) coatings. Thankfully Payne Glasses offers the cheapest 1.74 high index lenses, which means that they have the thinnest and lightest prescription lenses at a competitive price. You can choose between their fun array of frame sizes and colour detailing until you find the perfectly suitable frame for your face shape.
When it comes to eye health, there are a few tell-tale signs that you have to pay attention to. Your eyes can demonstrate a flood of different health issues, so pay(ne) attention!
Redness: We’ve all heard of red eye. This is when the eye vessels become blotches up and irritated, dictating that a bruise has formed beneath the eye. The medical term for it is subconjunctival hemorrhage. Normally you’ll have red eye in just one eye, and it is bound to clear up in a matter of a couple of weeks. If both your eyes are red and itchy, this could simply be the sign of allergies. Use over-the-counter medication to help moisturize your eyes and reduce the itchiness, and if you don’t see any progression in ten days then contact your doctor.
Dry Eye: This is often the root cause of spending too much time in front of those harmful blue computer rays. However, studying or reading for extended periods of time can also do the trick. Over time, such exposure heightens your prescription and requires you to seek the cheapest 1.74 high index lenses available out there to suit your lifestyle needs. With the speed of the internet, we know it may be hard to take an hour or two break without having FOMO (fear of missing out), but it may just be worth your overall health to take a brain break and relieve some stress with other activities.
