Identifying the Right Non-Prescription Colored Contacts for You

Colored Contact Lenses Halloween

Nowadays, there is a wide array of lens stores online or in your local community retailing colored lenses without the need for a consumer’s medical prescription.  Most of these non-prescription colored contact lenses are used by Halloween partygoers and costume players. As the buyers of these lenses only make use of these for fashion purposes, a prescription is not a requirement.

If this is your first time to purchase non-prescriptive colored contacts and you are a bit skeptical with what fits you best, here are tips to help you.

See an Optometrist

Just because you are only buying non-prescription contacts, doesn’t imply that you need not visit an optometrist anymore. That’s a misconception by most users, mind you. A licensed optometrist will help you identify the right contact size and brand for you. He will examine your eyes to determine if it’s safe for you to use decorative lenses. Being aware of important details regarding devices that would suit your eyes will make your online purchase fast and convenient.

Determine What Contact Color Complements Your Skin

Sad to say not all lens colors may suit you. Your skin tone is one great consideration. If you are dark-skinned, your options are limited to pale colors—lavender and ice blue are great examples. For fair-skinned users, light green and blue contacts will complement well their skin tone well. Actually, people with lighter skin tones have the greatest advantage as most contact colors will complement their skin color. If you have pale and light skin, you’re good with dark colored contacts such as deep green and chocolate brown. As has been mentioned however, any color can complement fair skin; these are only recommendations. If you don’t want to limit yourself with what is suggested, you can experiment and choose one that you feel fully blends with your physique and personality.

Find Costume-Matching Colored Contacts


Aside from color, design is another thing to bear in mind. There are decorative contacts made to match particular costumes. Some of these can be worn without the need for heavy makeup or complicated costumes—two things to resort using if you want to stand out.

Choose a Reputable Lens Store

Mind you, not all stores selling contact lenses are trustworthy. Choosing the more reliable ones increases the chances of you getting what you’ve paid for. Most established suppliers have a website of their own. You get to see product pictures from their sites with sizes and descriptions. They also provide relevant information about their company and their shipment requirements. Aside from that, they also give contact lens cleaning and stowage instructions. If the site you’ve been eyeing doesn’t provide as much information needed, find another one.

Scuba Diving Tips – Why You Shouldn’t Follow Your Bubbles

There are plenty of misconceptions about scuba diving and the rules that govern it. Among the first things you need to do if you want to become a certified diver and keep yourself safe on every dive is to do away with these misconceptions. Perhaps among the most common misconceptions are that you should never go faster than your bubbles and that you could just follow your bubbles when you go back up to the surface.


The first reason why you should ditch these concepts has to do with physics. Bubbles normally expand as they climb to the surface, and as they expand, their buoyancy is increased. If you paid attention in physics class, you’ll know that the increased buoyancy will make the bubbles travel faster towards the surface. You are therefore putting yourself at risk of ascending much faster than the recommended ascent rate of 60 feet per minute if you follow your bubbles.


The second reason why you should refrain from following your bubbles to the surface is that it is almost impossible to do so, especially if there’s poor visibility, a strong current, and several divers ascending at the same time. The third reason is that it’s very likely for you to inadvertently pass the bubble you planned to follow to the surface. When this happens, you’d know that you’re already going too fast even if you have weights with your diving gear, but it will be extremely difficult to slow down.


Finally, you’d do well to note that even the previously recommended ascent rate of 60 feet per minute is now deemed too fast and is only used in emergency situations. The ascent rate that’s now recommended by most dive instructors and dive masters is 30 feet per minute. Even if bubbles travel to the surface at an even 60 feet per minute (which they don’t, as discussed earlier), therefore, they’d still be going faster than the recommended ascent rate. This definitely makes it a bad idea to follow your bubbles to the surface.


Now here’s something very important for you to remember: The danger zone, where the greatest change in pressure occurs, is between 15 feet and the surface. When you reach this point, therefore, it is critical for you to ascend very slowly; it would be wise to go as slow as 10 feet per minute. It is also advisable to stop for 2 to 3 minutes at the 15-feet point before completing the ascent. So, forget the bubbles and focus on following your dive master’s instructions instead.
