Good eyesight is vital to maintaining quality of life, which is why it's important to see a qualified optometrist if your vision is failing. Your eyesight can be corrected through the use of visual aids like contact lenses or prescription lenses/eyeglasses. It's important to remember that eyesight continues to deteriorate based on factors like age, illness and environmental exposure. This is why timely intervention is necessary to slow down the rate of this deterioration. If you need prescription eyeglasses, the following are the most important things to consider before buying them:
1. Get a current prescription
Don't visit the eyeglass shop with a prescription from three years ago. Generally, eyeglass prescriptions are valid for two years, while contact lens prescriptions are valid for just one year. Children should also get annual prescriptions. One eye could have deteriorated in the time since your last prescription, with the other eye compensating so that you vision isn't affected. Prescription lenses are an investment, and a current prescription will ensure that your vision deficiencies are properly addressed so you get maximum value from your purchase. Also, you cannot use a contact lens prescription for eyeglasses or vice versa.
2. Size is important
When getting prescription glasses, functionality must always trump style. For instance, if you have presbyopia, an age-induced stiffening of the eye lens which makes focusing on close-vision tasks difficult, you may need multifocal lenses (e.g. progressive, bifocal or trifocal lenses). This is almost impossible to do with smaller lenses. Talk to the optometrist about the shortest height the lens can be while still maintaining efficacy. Only then can you start choosing frame styles and other aesthetic features.
3. Choose the right material
While eyeglasses are still so called, the lens material used today is actually very high-quality plastic, which makes them thinner, lighter and less breakable when dropped. Depending on your budget, you have several choices regarding material. They are as follows:

Hello, my name is Liam and I live in Alice Springs, Australia. I work pretty hard every day out on my farm, so it isn't unusual for me to have aches and pains. I hate going to the doctor so I normally pop a couple of painkillers or open a cold beer to deal with the discomfort. However, my wife kept on nagging me to see a doctor, which I eventually did. The doctor at Fidelity Health Choice discovered that I had a rare infection which was causing the pain. After a course of drugs, I fully recovered. I now attend regular appointments. I hope you enjoy my health and wellbeing blog.
